Problem with OC4j 10G 10g (10.1.2.0.2)

Question

Hi
I have a quite strange problem.
We are migrating one of our apllication from Oracle 10g Application Server 9.0.4 to Oracle 10g Application Server 10.1.2.0.2
For this first we build the application ear file using JDK 1.4.2_06.Then we deployed it in OC4J 10.1.2.0.2. sucessfully. But when I am testing the application, I got an issue on one of my JSP page where the user can click on a button and JSP page should display records.But it is not displaying any recods. But the records are showing good on Oracle 10g AS 9.0.4. For this I started the server in debug mode and server logs are displayed below.
Has it got anything to do with the application server. Do I need to modify any configurations in OAS? Can some one please help on this issue.
