Naveed Ahmad	3/13/2002	9:08:37 PM	Hi Mohammad
Mohammed Shabib	3/13/2002	9:09:32 PM	Hello
Naveed Ahmad	3/13/2002	9:10:17 PM	So how is it going?
Mohammed Shabib	3/13/2002	9:10:37 PM	Good
Mohammed Shabib	3/13/2002	9:11:05 PM	I finally got a chance to look at the code you sent.
Naveed Ahmad	3/13/2002	9:11:35 PM	Goog
Naveed Ahmad	3/13/2002	9:11:43 PM	Which one are you looking at
Naveed Ahmad	3/13/2002	9:11:56 PM	The first one or the second time I sent it.
Mohammed Shabib	3/13/2002	9:12:04 PM	The second time.
Naveed Ahmad	3/13/2002	9:12:23 PM	The Employee java bean?
Mohammed Shabib	3/13/2002	9:12:35 PM	Yes
Naveed Ahmad	3/13/2002	9:13:33 PM	So have you tried Rahuls envionment?
Mohammed Shabib	3/13/2002	9:13:57 PM	I also tryed running the Test.java file you sent, but I couldn't figure out how to add the jar files from jdbc apis to the class files
Naveed Ahmad	3/13/2002	9:14:12 PM	Basically everyone can pick a table and create similar code for it.
Naveed Ahmad	3/13/2002	9:14:28 PM	Were you able to get the jar file ?
Mohammed Shabib	3/13/2002	9:14:31 PM	Yes
Naveed Ahmad	3/13/2002	9:14:40 PM	if youron dos
Mohammed Shabib	3/13/2002	9:14:58 PM	i am
Naveed Ahmad	3/13/2002	9:15:12 PM	set CLASSPATH=mysql....jar:mysql_uncomp.jar
Mohammed Shabib	3/13/2002	9:15:28 PM	oh.. thats it? I will give it a try after the meeting
Naveed Ahmad	3/13/2002	9:15:35 PM	you need to put the full path as well
Mohammed Shabib	3/13/2002	9:15:40 PM	yes
Naveed Ahmad	3/13/2002	9:16:05 PM	set CLASSPATH=c:\jars\mysql_comp.jar:c:\jars\mysql_uncomp.jar
Naveed Ahmad	3/13/2002	9:16:35 PM	Infac t you should put a dot in the CLASSPATH to ]
Naveed Ahmad	3/13/2002	9:16:37 PM	like
Naveed Ahmad	3/13/2002	9:17:07 PM	set CLASSPATH=.:c:\jars\mysql_comp.jar:c:\....
Naveed Ahmad	3/13/2002	9:17:34 PM	The dot tells it to look for classes in the current directory as well.
Mohammed Shabib	3/13/2002	9:17:48 PM	oh
Naveed Ahmad	3/13/2002	9:17:59 PM	But you also need mysql to be running .
Naveed Ahmad	3/13/2002	9:18:28 PM	And select the user id and password on your env.
Mohammed Shabib	3/13/2002	9:18:30 PM	on my pc?
Naveed Ahmad	3/13/2002	9:18:57 PM	It will be best if you use Rahuls env and ask him the user id and password and database name.
Mohammed Shabib	3/13/2002	9:19:04 PM	ok.
Brian Burgner	3/13/2002	9:19:14 PM	Hello
Brian Burgner	3/13/2002	9:19:17 PM	Sorry I'm late
Mohammed Shabib	3/13/2002	9:19:24 PM	Hi
Naveed Ahmad	3/13/2002	9:19:24 PM	Hi Brian.
Naveed Ahmad	3/13/2002	9:19:28 PM	Its ok.
Mohammed Shabib	3/13/2002	9:20:46 PM	Did you get my email Brian?
Brian Burgner	3/13/2002	9:21:06 PM	about JMetric? yes
Naveed Ahmad	3/13/2002	9:21:09 PM	So which part are you doing for the hw?
Brian Burgner	3/13/2002	9:21:17 PM	Part B
Brian Burgner	3/13/2002	9:21:53 PM	So, is Rahul online via ICQ or something like that? If so, maybe we should use that for this chat.
Naveed Ahmad	3/13/2002	9:22:28 PM	No he is not online on icq
Brian Burgner	3/13/2002	9:22:38 PM	ok
Brian Burgner	3/13/2002	9:22:55 PM	do we want to talk about the homework first or the project?
Naveed Ahmad	3/13/2002	9:23:14 PM	Let talk about the homework first.
Naveed Ahmad	3/13/2002	9:23:52 PM	So you both are working together?
Mohammed Shabib	3/13/2002	9:23:56 PM	yes
Naveed Ahmad	3/13/2002	9:24:01 PM	Which part are you doing?
Mohammed Shabib	3/13/2002	9:24:09 PM	B
Naveed Ahmad	3/13/2002	9:24:28 PM	i.e. the softwares to gather the matrices.
Brian Burgner	3/13/2002	9:24:42 PM	yes
Naveed Ahmad	3/13/2002	9:25:04 PM	ok
Naveed Ahmad	3/13/2002	9:26:06 PM	So I guess I am Rahul will make a group together for part A.
Brian Burgner	3/13/2002	9:27:09 PM	yes. don't we have others though? cesar and sadaf?
Brian Burgner	3/13/2002	9:27:18 PM	are they still in the course and on the team?
Naveed Ahmad	3/13/2002	9:27:36 PM	I dont know about ceasar.
Naveed Ahmad	3/13/2002	9:27:54 PM	But I know that Sadaf is gone for vacations
Naveed Ahmad	3/13/2002	9:27:59 PM	would be back soon,
Naveed Ahmad	3/13/2002	9:29:10 PM	Hi Ceasar.
Brian Burgner	3/13/2002	9:29:21 PM	that answers that question!
Cesar R. (Rob) Nunez	3/13/2002	9:29:35 PM	Greetings!
Brian Burgner	3/13/2002	9:29:43 PM	Hi Cesar. We were just talking about whether or not we still have 6 team members :)
Naveed Ahmad	3/13/2002	9:29:48 PM	Does anyone know which lecture is the most relavant to matrices i.e. was it tought before the mid terms?
Brian Burgner	3/13/2002	9:30:26 PM	10 - 12 were on metrics
Naveed Ahmad	3/13/2002	9:32:01 PM	i see.
Naveed Ahmad	3/13/2002	9:32:42 PM	So want to discuss how to proceed with project?
Brian Burgner	3/13/2002	9:32:52 PM	hey cesar...for the homework, naveed and rahul are doing part a and mohammed and i are doing part b. you and sadaf each need to choose a group to be a part of. sadaf is out of town so it looks like you get to pick what part you want to do. thoughts?
Naveed Ahmad	3/13/2002	9:32:54 PM	We have most of the people here.
Naveed Ahmad	3/13/2002	9:34:27 PM	Helooo.
Cesar R. (Rob) Nunez	3/13/2002	9:34:44 PM	I'll join group A.
Brian Burgner	3/13/2002	9:35:05 PM	ok. just wanted to get that taken care of before discussing the project :)
Naveed Ahmad	3/13/2002	9:35:25 PM	Ok lets discuss how to proceed.
Brian Burgner	3/13/2002	9:35:25 PM	naveed, i feel silly saying this, but i just realized yesterday that your emails had attachments! i kept looking on sourceforge for code
Mohammed Shabib	3/13/2002	9:35:37 PM	me too
Naveed Ahmad	3/13/2002	9:35:49 PM	Oh.
Brian Burgner	3/13/2002	9:35:50 PM	i've set up java and tomcat and looked at the jsps so i'm ready to actually do development for our project
Naveed Ahmad	3/13/2002	9:36:10 PM	Have you looked at the last attachment.
Naveed Ahmad	3/13/2002	9:36:25 PM	In whoch I sent EmplyeeQuery.java and EmployeeInfo.java
Naveed Ahmad	3/13/2002	9:36:33 PM	Here is the plan.
Naveed Ahmad	3/13/2002	9:36:48 PM	All of us can quickly finish the java beans forst.
Naveed Ahmad	3/13/2002	9:37:11 PM	For each table you can make a Query and Info class.
Naveed Ahmad	3/13/2002	9:37:42 PM	The EmplyeeInfo is basically a datastructure which maps corresponding th a table (employee) table.
Naveed Ahmad	3/13/2002	9:38:18 PM	The EmployeeQuery.java file has methods to retrieve, update delete and insert data into that table.
Naveed Ahmad	3/13/2002	9:39:16 PM	Check you the main method which is the test method to test the mehtod if they actually insert or select data (and populate the EmployeeInfo structure).
Naveed Ahmad	3/13/2002	9:39:32 PM	You need to have mysql running.
Naveed Ahmad	3/13/2002	9:39:53 PM	With the mysq_comp.jar and mysql_uncomp.jar in your classpath.
Naveed Ahmad	3/13/2002	9:40:24 PM	Basically I want us to pick the tables each of us wants to work on.
Naveed Ahmad	3/13/2002	9:40:48 PM	The second phase would be to make the servlets and jsp.
Naveed Ahmad	3/13/2002	9:41:26 PM	If we have all the beans for all the tables we can easily use them in our servlets.
Naveed Ahmad	3/13/2002	9:41:47 PM	The first email attachment the tar file.
Naveed Ahmad	3/13/2002	9:42:05 PM	Is an example of a jsp , serlvet and a java bean working in cordination.
Naveed Ahmad	3/13/2002	9:42:25 PM	That is the complete architecture of the application.
Naveed Ahmad	3/13/2002	9:43:08 PM	But the first step is to make and unit test our business java beans (the ones which directly talk to the data base).
Brian Burgner	3/13/2002	9:43:15 PM	The Software Architecture Document contains all of the classes, right?
Naveed Ahmad	3/13/2002	9:43:33 PM	Well, I need to modify the diagrams a bit.
Naveed Ahmad	3/13/2002	9:44:06 PM	Let me show you the table diagram.
Brian Burgner	3/13/2002	9:44:32 PM	ok
Naveed Ahmad	3/13/2002	9:45:17 PM	Can everyone look at the diagram.
Cesar R. (Rob) Nunez	3/13/2002	9:45:35 PM	Yes!
Mohammed Shabib	3/13/2002	9:45:37 PM	yes
Naveed Ahmad	3/13/2002	9:45:43 PM	ok
Naveed Ahmad	3/13/2002	9:46:06 PM	So here are all the tables we need to write our java beans for.
Naveed Ahmad	3/13/2002	9:46:15 PM	I wrote for the Employee table.
Naveed Ahmad	3/13/2002	9:46:26 PM	This table diagram is in the architecture diagram.
Naveed Ahmad	3/13/2002	9:46:47 PM	Ive added 2 new fiels loging and passowrd to each of the employee and candidate table.
Brian Burgner	3/13/2002	9:47:26 PM	one of the things that confused me about the design was that here we have an employee table and elsewhere we have an employer table. which do we actually have in our system? i thought it was only emplyers
Naveed Ahmad	3/13/2002	9:48:12 PM	This shoudl be employer.
Naveed Ahmad	3/13/2002	9:48:38 PM	Its a mistake here.
Naveed Ahmad	3/13/2002	9:49:01 PM	I'll change the names of the java files to Employer*
Brian Burgner	3/13/2002	9:49:18 PM	that helps clear things up. since i wasn't here last semester, i thought maybe i had missed something and each employer had lots of employees or something like that! this makes it a little simpler
Naveed Ahmad	3/13/2002	9:49:30 PM	Do you want me to go over the code?
Cesar R. (Rob) Nunez	3/13/2002	9:49:38 PM	By all means, please do!
Naveed Ahmad	3/13/2002	9:49:39 PM	For the employer table?
Naveed Ahmad	3/13/2002	9:49:41 PM	ok
Naveed Ahmad	3/13/2002	9:50:24 PM	First step.
Naveed Ahmad	3/13/2002	9:50:36 PM	I created a emploer table in mysq.
Naveed Ahmad	3/13/2002	9:50:53 PM	It has all the firlds as in the digram.
Naveed Ahmad	3/13/2002	9:51:01 PM	Also added a sample value.
Naveed Ahmad	3/13/2002	9:52:13 PM	This is the way to run scripts on mysql
Naveed Ahmad	3/13/2002	9:52:22 PM	Mysql has no user id or password set.
Naveed Ahmad	3/13/2002	9:52:35 PM	It makes my life easier.
Naveed Ahmad	3/13/2002	9:53:04 PM	I am keeping all the java beans in the model folder.
Naveed Ahmad	3/13/2002	9:53:20 PM	Lets look at EmployeeInfo.java
Naveed Ahmad	3/13/2002	9:53:25 PM	Employee= Emplyer
Brian Burgner	3/13/2002	9:53:32 PM	heh
Naveed Ahmad	3/13/2002	9:53:47 PM	:)
Naveed Ahmad	3/13/2002	9:54:03 PM	It has member variables defined corresponding to the table.
Naveed Ahmad	3/13/2002	9:54:12 PM	2 contructors.
Naveed Ahmad	3/13/2002	9:54:40 PM	The second constrcutor is to initialise a new object with values.
Naveed Ahmad	3/13/2002	9:54:51 PM	The first one just puts empty strings.
Naveed Ahmad	3/13/2002	9:55:21 PM	Though we should have set and get methods for each of the members.
Naveed Ahmad	3/13/2002	9:55:56 PM	But that would have been a lot of typing so I will make them puclic, to access them directly.
Naveed Ahmad	3/13/2002	9:56:07 PM	Is it simple enough yet?
Cesar R. (Rob) Nunez	3/13/2002	9:56:38 PM	Having no java experience or background, I can see that it is somewhat simple!
Naveed Ahmad	3/13/2002	9:56:49 PM	Good.
Naveed Ahmad	3/13/2002	9:57:03 PM	I would recommand using Rahuls env.
Brian Burgner	3/13/2002	9:57:05 PM	it does look pretty straightforward, and after we've all done a class or two, we should get it pretty well
Mohammed Shabib	3/13/2002	9:57:13 PM	yes
Naveed Ahmad	3/13/2002	9:57:19 PM	And ask him to take care of setting up database ids etc.
Naveed Ahmad	3/13/2002	9:57:31 PM	It will save your time.
Naveed Ahmad	3/13/2002	9:57:45 PM	Ok lets look at the Query file.
Naveed Ahmad	3/13/2002	9:58:08 PM	The EmplueeQuery class is to be used by some client code.
Naveed Ahmad	3/13/2002	9:58:21 PM	e.g. it will be instantiated by a servlet .
Naveed Ahmad	3/13/2002	9:58:43 PM	or any other application which wants to deal with the employee table.
Naveed Ahmad	3/13/2002	9:59:05 PM	In our test case it will be instantiated by our main method.
Naveed Ahmad	3/13/2002	9:59:39 PM	You can define a main method in each of your classes.
Naveed Ahmad	3/13/2002	10:00:19 PM	The person instanitating the class will be resposible to give the class the Connection.
Naveed Ahmad	3/13/2002	10:00:42 PM	The connection id your gateway to the database.
Brian Burgner	3/13/2002	10:01:03 PM	quick cygwin question - my root directory in cygwin is d:\cygwin. how do i get to other portions of my hard drive in cygwin? thanks!
Naveed Ahmad	3/13/2002	10:02:11 PM	/cydrive/d/
Brian Burgner	3/13/2002	10:02:28 PM	is cygdrive a link that you set up? i'm not seeing it on my cygwin
Naveed Ahmad	3/13/2002	10:02:43 PM	yah I make a sybolic link
Brian Burgner	3/13/2002	10:02:52 PM	also, is someone here 13115612 in icq?
Naveed Ahmad	3/13/2002	10:02:58 PM	try to cd /cygdrive/d
Brian Burgner	3/13/2002	10:02:59 PM	or is that rahul's?
Brian Burgner	3/13/2002	10:03:13 PM	hey, that worked. thanks!
Naveed Ahmad	3/13/2002	10:03:25 PM	I dont see him here.
Naveed Ahmad	3/13/2002	10:03:30 PM	Your welcome.
Naveed Ahmad	3/13/2002	10:03:53 PM	So I vreated an instance of EmployeeQuery
Naveed Ahmad	3/13/2002	10:04:03 PM	Initilised it with a connection object.
Naveed Ahmad	3/13/2002	10:04:23 PM	We will first look at the selectEmployee method.
Naveed Ahmad	3/13/2002	10:05:08 PM	The way to communicate to the EmployeeQuery is through
Naveed Ahmad	3/13/2002	10:05:19 PM	setEmployeeInfo and getEmployeeInfo.
Naveed Ahmad	3/13/2002	10:05:55 PM	Lets say we know the empId for a particular employee.
Naveed Ahmad	3/13/2002	10:06:10 PM	We create an object of EmployeeInfo.
Naveed Ahmad	3/13/2002	10:06:22 PM	ei.
Naveed Ahmad	3/13/2002	10:06:32 PM	set ei.EmpId=2
Naveed Ahmad	3/13/2002	10:06:46 PM	This is the only information we know about the employee.
Naveed Ahmad	3/13/2002	10:07:11 PM	Use the setEmplyee mehtod of the EmplyeeQuery object to set the object.
Naveed Ahmad	3/13/2002	10:07:59 PM	After setting the partailly populated employeeInfo object.
Naveed Ahmad	3/13/2002	10:08:13 PM	I call the selectEmployee method of the EmployQuery
Naveed Ahmad	3/13/2002	10:08:49 PM	The selectEmplyee method creates a query.
Naveed Ahmad	3/13/2002	10:09:25 PM	The result set picks all the values from the table and populates the ei member variables.
Naveed Ahmad	3/13/2002	10:09:55 PM	After this I call the eq.getEmplyeeInfo method.
Naveed Ahmad	3/13/2002	10:10:12 PM	This returns the fully populated employeeInfo object.
Naveed Ahmad	3/13/2002	10:10:41 PM	I can print the empName or any other field I want to.
Naveed Ahmad	3/13/2002	10:12:10 PM	So I compiled and ran the test.
Naveed Ahmad	3/13/2002	10:12:15 PM	It works.
Naveed Ahmad	3/13/2002	10:12:35 PM	The other methods work similarly.
Naveed Ahmad	3/13/2002	10:13:03 PM	I will tar the directory again and send it out to you .
Naveed Ahmad	3/13/2002	10:13:41 PM	If you are working on linux you may have to change the compile.sh and run.sh slightly .
Naveed Ahmad	3/13/2002	10:14:03 PM	Do you think you enough to get started?
Brian Burgner	3/13/2002	10:14:07 PM	on rahul's machine, do you expects us to all have a tomcat directory in our home directories? where will we do our individual work and where will we integrate it?
Naveed Ahmad	3/13/2002	10:14:33 PM	to write the java beans you dont need the tomcat directory.
Naveed Ahmad	3/13/2002	10:14:51 PM	You can write java beans flat in your home and compile and test them.
Naveed Ahmad	3/13/2002	10:15:05 PM	You need tomcat to write servlets and jsp's
Brian Burgner	3/13/2002	10:15:26 PM	so we'll tackle that configuration issue after everyone has created their beans?
Naveed Ahmad	3/13/2002	10:15:39 PM	Yes.
Naveed Ahmad	3/13/2002	10:15:55 PM	I wish Rahul was here so we could figure out that part today.
Brian Burgner	3/13/2002	10:16:07 PM	i'm chatting with him on icq, but he can't get into netmeeting
Naveed Ahmad	3/13/2002	10:16:23 PM	But if we guys can get over the java beans part quickly we can get to the tocat part quickly.
Naveed Ahmad	3/13/2002	10:17:10 PM	Ok let me show how this bean is used in the servlet.
Naveed Ahmad	3/13/2002	10:17:28 PM	The control folder will have the servets.
Cesar R. (Rob) Nunez	3/13/2002	10:18:01 PM	When you say, we can write, compile, and test the java beans without Tomcat, what tool should we be using to do this?
Naveed Ahmad	3/13/2002	10:18:12 PM	I create a BaseControl.java which ingerits from HttpServlet
Naveed Ahmad	3/13/2002	10:18:22 PM	All Servlets need to inherit from it.
Brian Burgner	3/13/2002	10:18:24 PM	i think we can use any editor we want and then compile with javac and run with java
Naveed Ahmad	3/13/2002	10:18:36 PM	This java file has helpful methods.
Cesar R. (Rob) Nunez	3/13/2002	10:18:41 PM	Ok.
Naveed Ahmad	3/13/2002	10:18:42 PM	For creating a connection
Naveed Ahmad	3/13/2002	10:18:46 PM	Closing a connection
Naveed Ahmad	3/13/2002	10:18:51 PM	StrintoInt
Naveed Ahmad	3/13/2002	10:18:57 PM	NoNull
Naveed Ahmad	3/13/2002	10:19:28 PM	Forwading the control to the jsp. The jsp is the one to do the html part.
Naveed Ahmad	3/13/2002	10:20:07 PM	You write your code either in the doPost method or doGet.
Naveed Ahmad	3/13/2002	10:20:24 PM	the doPost method recieves 2 parameters .
Naveed Ahmad	3/13/2002	10:20:29 PM	request and response.
Naveed Ahmad	3/13/2002	10:20:45 PM	The request has all the attributeds posted by a form
Naveed Ahmad	3/13/2002	10:21:19 PM	This serlvet expects a empId
Naveed Ahmad	3/13/2002	10:21:46 PM	http://localhost/distrimon/servlet/ShowEmployee?empId=1
Naveed Ahmad	3/13/2002	10:22:29 PM	Most of the code is like the code in the main method to test the bean.
Naveed Ahmad	3/13/2002	10:23:18 PM	Once I get the populated ei object with all the values from the tbale.
Naveed Ahmad	3/13/2002	10:23:42 PM	I put the whocl object into the request scope.
Naveed Ahmad	3/13/2002	10:24:05 PM	And next step is to forward to a jsp
Naveed Ahmad	3/13/2002	10:24:28 PM	the forward method is in the BaseControl.java
Naveed Ahmad	3/13/2002	10:25:36 PM	I retieve the ei object from the request scopel
Naveed Ahmad	3/13/2002	10:25:48 PM	and print out the values on the jsp
Naveed Ahmad	3/13/2002	10:26:24 PM	I will show you how it works.
Naveed Ahmad	3/13/2002	10:26:30 PM	on the browser.
Naveed Ahmad	3/13/2002	10:27:29 PM	So based on the empId=1
Naveed Ahmad	3/13/2002	10:27:45 PM	It brought the remaining values from the mysql table.
Naveed Ahmad	3/13/2002	10:28:09 PM	We need to have tomcat for this part of it.
Naveed Ahmad	3/13/2002	10:28:14 PM	i.e. servlet and jsp
Naveed Ahmad	3/13/2002	10:28:37 PM	But for all the java files in the model we can test by our main method.
Naveed Ahmad	3/13/2002	10:29:01 PM	But mysql and the jar files are a must for them
Cesar R. (Rob) Nunez	3/13/2002	10:29:16 PM	Can you quickly tell me the difference between jsp and servlet, java beans?
Naveed Ahmad	3/13/2002	10:29:54 PM	java bean is a java class
Naveed Ahmad	3/13/2002	10:29:58 PM	nothing more.
Naveed Ahmad	3/13/2002	10:30:12 PM	Just like you c++ classes.
Naveed Ahmad	3/13/2002	10:30:34 PM	Java servlet runs in your servlet engine.
Cesar R. (Rob) Nunez	3/13/2002	10:30:55 PM	Ok.
Naveed Ahmad	3/13/2002	10:31:00 PM	You implement the doPost method of a servlet to act on an invoation.
Naveed Ahmad	3/13/2002	10:31:19 PM	For exampl e whe n I typed the URL.
Naveed Ahmad	3/13/2002	10:31:24 PM	http://localhost/distrimon/servlet/ShowEmployee?empId=1
Naveed Ahmad	3/13/2002	10:31:55 PM	the code in the doPost method got invoked for the servlet
Naveed Ahmad	3/13/2002	10:32:39 PM	A jsp eventually gets converted into a servlet.
Brian Burgner	3/13/2002	10:32:50 PM	why do we have servlets instead of all jsps?
Naveed Ahmad	3/13/2002	10:32:54 PM	But you can mix html with java code easily.
Naveed Ahmad	3/13/2002	10:33:04 PM	A jsp also runs in a servlet engine.
Naveed Ahmad	3/13/2002	10:33:31 PM	You write the java code in <% %>
Naveed Ahmad	3/13/2002	10:33:33 PM	tags
Naveed Ahmad	3/13/2002	10:33:49 PM	Anything outseide it is html
Cesar R. (Rob) Nunez	3/13/2002	10:34:06 PM	Right. It's just like an ASP page.
Naveed Ahmad	3/13/2002	10:34:10 PM	So you use jsp to display information
Naveed Ahmad	3/13/2002	10:34:17 PM	Exactly!
Cesar R. (Rob) Nunez	3/13/2002	10:34:35 PM	And so you're java bean is actually a COM component.
Naveed Ahmad	3/13/2002	10:34:38 PM	Servlet acts like a controller or manager between jsp and java classes.
Naveed Ahmad	3/13/2002	10:34:48 PM	Correct
Naveed Ahmad	3/13/2002	10:35:01 PM	java classes are your business end.
Cesar R. (Rob) Nunez	3/13/2002	10:35:06 PM	So the jsp is accessed by the user. the jsp calls the servlet which in turn calls the java bean to get at the database.
Naveed Ahmad	3/13/2002	10:35:15 PM	Correct.
Naveed Ahmad	3/13/2002	10:35:29 PM	The servlets are always transparent
Naveed Ahmad	3/13/2002	10:35:50 PM	Because after exexuting they forward the control to a jsp
Naveed Ahmad	3/13/2002	10:36:01 PM	Let me dra a diagram
Naveed Ahmad	3/13/2002	10:38:11 PM	basically a jsp or an html sends info to a servlet
Naveed Ahmad	3/13/2002	10:38:18 PM	using post or get
Naveed Ahmad	3/13/2002	10:38:30 PM	the servlet picks the values from the request.
Naveed Ahmad	3/13/2002	10:38:39 PM	Instantiates a java bean.
Naveed Ahmad	3/13/2002	10:38:53 PM	Sets the values of the java beans, calls operations
Naveed Ahmad	3/13/2002	10:39:02 PM	get values from the java beans
Naveed Ahmad	3/13/2002	10:39:12 PM	forwards them to another jsp
Naveed Ahmad	3/13/2002	10:39:25 PM	The servlet is never see by the user.
Cesar R. (Rob) Nunez	3/13/2002	10:39:42 PM	Understood! So the java bean does respond to the servlet unlike your diagram?
Naveed Ahmad	3/13/2002	10:39:43 PM	The servlet also creates the jdbc connection
Naveed Ahmad	3/13/2002	10:39:55 PM	The java bean
Naveed Ahmad	3/13/2002	10:40:07 PM	Or the EmployeeInfo object can be passed to the jsp
Naveed Ahmad	3/13/2002	10:40:13 PM	for display purposes.
Cesar R. (Rob) Nunez	3/13/2002	10:40:30 PM	Ok.
Naveed Ahmad	3/13/2002	10:41:03 PM	Like the ei was set in the reqeust
Naveed Ahmad	3/13/2002	10:41:27 PM	This is the MVC architecture.
Naveed Ahmad	3/13/2002	10:41:43 PM	Extrme cases are that you can write ALL your code in a jsp
Naveed Ahmad	3/13/2002	10:42:01 PM	Or all your code in a servlet (even the htm prints).
Naveed Ahmad	3/13/2002	10:42:28 PM	But this is the corrst way to do it.
Cesar R. (Rob) Nunez	3/13/2002	10:42:28 PM	Right! Just like we could have skipped the servlet - perhaps.
Naveed Ahmad	3/13/2002	10:42:39 PM	Yah
Naveed Ahmad	3/13/2002	10:42:53 PM	You can instanitate the object in a jsp
Naveed Ahmad	3/13/2002	10:43:00 PM	But this really cluuters the jsp
Cesar R. (Rob) Nunez	3/13/2002	10:43:24 PM	Right again. This architecture is what we use at work only on a microsoft shop.
Naveed Ahmad	3/13/2002	10:43:26 PM	Practice is that the only code to be wrtten in a jsp is the code for display purposes.
Naveed Ahmad	3/13/2002	10:43:51 PM	liek iterating a vector etc
Naveed Ahmad	3/13/2002	10:44:21 PM	So are you guys ready to work on the java beans?
Mohammed Shabib	3/13/2002	10:44:24 PM	yes
Naveed Ahmad	3/13/2002	10:44:57 PM	Can you take 3 tables.
Naveed Ahmad	3/13/2002	10:45:05 PM	Job Applicant
Naveed Ahmad	3/13/2002	10:45:10 PM	Resume Pool
Naveed Ahmad	3/13/2002	10:45:15 PM	and Web Attributes.
Cesar R. (Rob) Nunez	3/13/2002	10:45:32 PM	I might run into a few questions once I dive in the code syntax wise, but otherwise I feel comfortable as well.
Naveed Ahmad	3/13/2002	10:45:44 PM	Which tables you want to take?
Mohammed Shabib	3/13/2002	10:45:59 PM	I'll take Job Applicant
Cesar R. (Rob) Nunez	3/13/2002	10:46:12 PM	Submitted Resume

Naveed Ahmad	3/13/2002	10:46:54 PM	how about Resume Pool
Naveed Ahmad	3/13/2002	10:47:35 PM	It is quite simple one you get an example running.
Mohammed Shabib	3/13/2002	10:47:49 PM	I'll try it
Cesar R. (Rob) Nunez	3/13/2002	10:48:11 PM	I'll give a shot!
Naveed Ahmad	3/13/2002	10:48:15 PM	Ask Rahul to get you an account on his machine.
