We are using eclipse 3.7 and deploying the reports in BEA WL10.0.2 with JDK 1.5. We are creating only one engine and wrapping it in singleton. We are closing Task and Report documents properly. Reports started working fine after bouncing the server. This has become high priority issue in production. Any help on this is highly appreciated.

Thanks,
Pavan.

Can you open a bugzilla entry for this? I assume this is on Linux? BTW have you tried something like:

Hi Pavan,

I have investigated the theme and written the result down in the issue:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=401068

Do your reports contain crosstabs?


Best regards,
Vlad

You might try downloading a copy of 4.2.2 and setting it up to run a quick check on if it works with your actual application. That would definitely be the most absolute way to check that it'll work for you, anyways.
