Dear BIRT Admins,

I've ran into an issue with BIRT recently, this exception is thrown in the engine code when running the report. We are currently using BIRT 2.6.0. Unfortunately it is not occuring intermittently and so it is difficult to track down.

Do you have any feedback as to what can be causing this issue?

My guess is either the disk is full or you don't have write permissions. I am moving this topic to appropriate forum to solicit more responses.

[vnguyen]

That averma for your quick reply & thanks for moving the thread to the correct location.

That was my first thought too but there is actually plenty of disk space (over 25 GB) on the drive where we had installed jboss (with BIRT).

Btw, the exception is occuring during rendering time.

It seem as though BIRT is throwing a null pointer exception on the CacheList.remove() method while storing cached data blocks as it was writing the RPTDOCUMENT content.

[vnguyen]

Another thought, would this be related to any threading or locking issues with the BIRT Core?

[averma]

Not very likely, could be related to temporary document files, try changing the folder location for BIRT_VIEWER_DOCUMENT_FOLDER in web.xml and see if that makes any difference.

Thanks for your suggestion.

I've also tried that (among other configuration changes) but I was not able to reproduce the issue either.

Prior to this exception, all of our reports run successfully. Once this exception occured, we cannot run any of our 60 reports and the only way to get around this is to restart the application (Jboss) application server.

[averma]

Sounds like a temporary file cache cleanup issue.

Hi Irnit,
Are you using persisted variables or Java Objects in your report?

Hello,

I am using JAVA Objects. Is there anyway to avoid it. Other then Stop(tomcat) the service and delete Documents folder manually.

thanks
lrnit

[averma]

Are these Java Objects serializable?

Hi,

In My most of the reports i am creating data set by calling API(Written in java) . And using them in report.
I am creating arraylist of hash map to store data in API and return it.

As those data is coming from application not directly from database.


What could be the reason of this problem.

Please help as of now we have only one solution i.e, stop the service and and delete Files from "Documents" Folder manually .
