Hi nelly

No need to do much
I hope u are aware of JDBC-ODBC Driver and they are supported by sdk1.4

First create a DSN using ODBC in control pannel
later for JSP to connect to Database

use the following code

<%
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:<DSN name>")
%

provide DSN name after the second colon.
In this way you are connected to your data base and you can futher query your database using statement object .

For futher help
mail adityabakle@gmail.com

  1. You should know that urgency on your side will not speed up process on our side, we have right to live too...
  2. Any reason for Tomcat 4 when there s Tomcat 6? If not, either use latest Tomcat 5 or go for Tomcat 6 as is working fine. (http://tomcat.apache.org/)
  3. Oracle website holds numerous examples, like these and you can have look also on How-To examples.

First thing Amrita is DO NOT CONNECT DIRECTLY TO A DATABASE FROM A JSP.
It is a bad practice to do so. It looks like you are still just studying JSPs, so from the start itself learn how to correctly design you web applications by separating the processing logic and the User Interface. Check this thread by Peter for a good tutorial on how you should go about development is JSPs.
And one more thing please use code tags while posting code, look here for more information.

Note:-
A quick fix exists but I simply will not give it to you cause, you would then just implement the quick fix and skip the rest of the advice.

That query would belong to the Javascript forum (*I guess*), But you have to show us the relevant piece of code, So that we can point out where you are going wrong.
If you still would like to get some code samples I suggest you look at the Code Snippets section of Daniweb to see if you can find something useful or else google is your friend.

we can connect the jsp page with database also by datasource. in datasource procedure
we are creating first a jdvc provider then create a datasource. then give some authentication and name of server like server1 or manager01 etc..
then give database name to which we want to connect.
and then give the test coneection command.
and get the successfully connection with that database
