How to use a single jsp as template

hi I have a jsp with a layout. it means the jsp has menu on the left and header on the top. now for every different call the center part of the jsp should change. Is this possible?
I mean for every different call a different jsp should be included in the center of the layout jsp. If this is possible it will be of so much help. kindly help?

Case 1:
u have only fenum and fetxt to load
then create the datasource with both the fiels and load data
Case 2: you other fields as the attributes of fenum and you have fetxt
Sol1:
then create one datasource for fenum + attributes
2nd datasource for fenum + fetxt
Sol2: create one datasource with fenum + attributes + fetxt
the reason we have seperate datasource for text is that the descriptions of the field fenum may not be so frequent as the master data change, depending on the scenario it could be vice versa also.

          if (cookie_session == null) {
               sesID = session.getId();

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is
whenever the list is changed the page shuold be refreshed with the selected item info.
I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.

We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
Do you know of any way to dynamically query the the Oracle database in Javascript

How to use threads in JSP???

hello
i want to use threads with JSP.
i want to write a jsp page which will
start 2 different threads. the 1st thread should just display a message and the second page should redirect this page to another jsp page.
till the redirection is goin on, the message should be displayed in the browser from the 1st thread.
i dont know actually how to use threads in JSP by implementing the Runnable insterface, if not m then how do i do it ??
thanx
Kamal Jai

Why do you want to use threads to do this ??
If you write a message and do a redirection, the message will be displayed until the other page will be loaded into the browser...
I already launched a thread from a JSP but it was for a four hour process where the user can close his browser windows.

How to use ColumnList MOde in Query Template

Hi,
I am working on SAP MII 11.5 and having trouble with SQL Query Template with Column List mode.
It is throughing an error "Enter a table Name.
Please help me in this regard

You will need to use the Group parameter with the table name.
<PARAM NAME="Group" VALUE="Employees">
You can also set it with javascript for interactive use that would emulate the Template Editor:
document.APPLET.getQueryObject().setGroup("Employees");

Google is your friend, so search on Google for Tomcat 6.0 and it will show you were you can get it from.
Take a look at the Apache Tomcat Version Chart here:
http://tomcat.apache.org/whichversion.html
Servlet 2.5/ JSP 2.1 -------------- Tomcat 6.0.10
Servlet 2.4/ JSP 2.0 -------------- Tomcat 5.5.23
Since you want Servlet 2.4 and JSP 2.0 which are required for JSTL 1.1, you could get Tomcat 5.5.x , instead of Tomcat 6.0.x
Although I don't know if Tomcat 6 is backwards compatible with Servlet 2.4 and JSP 2.0 , if it is then it's cool to get Tomcat 6.x
web.xml - Servlet 2.4 Version
<?xml version="1.0" encoding="UTF-8"?>
