Thanks for your reply. I am not find the solution yet.
@Mohan - Originally i am doing migration from was 5.1 to rad7. I am having nested tags in my jsp page.
It's working properly in was 5.1. but in rad7 it showing the error page which i described in my first post.
I think there will be a problem in <nested:hidden> within the <nested:iterate> tag. I am trying to find the out the exact problem.
@Joe Ess - yes i am using the same code in both the servers. but you knew, jdk, jsp servlet versions differs in rad7 when comparing was5.1.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
