java.lang.IllegalStateException: The viewing session is not available or has expired. [message #1020855]

I have a number of BIRT reports that I open all at once in a browser by opening their links, all bookmarked in a single directory, in new tabs. This means that I might open say 7 reports all at once.

When I do that, I quite often get the error:

java.lang.IllegalStateException: The viewing session is not available or has expired.

When loaded one at a time, the reports all load OK. I assume this error relates to some kind of overload or lack of resources.

Does anyone know how to configure BIRT to cope with loading a number of reports all at the same time?

What version of BIRT are you using? Are you using the BIRT Tag libs or something like iFrames?

I am running the reports with the "run?__report=" parameter. I have tried with and without the "__overwrite=true" parameter.

I am using BIRT 4.2.2 with JBoss AS 7.

I can confirm that the issue goes away when I stagger the report loading. Using a bash script to "sleep 15" before opening each BIRT URL results in the reports being loaded properly.

what happens if you use preview? instead of run?

Using preview doesn't seem to make any difference.

I am seeing the same issue with. I have links to reports which open in an internal viewer within my web application. The issue occurs regardless of what servlet i hit.

I am using BIRT 4.2.2 and Tomcat 6.0.32

The issue can be mitigated by opening a new browser tab and pasting the birt url directly into the browser. Once this has been done, and for what appears to be an arbitrary period of time, reports shown in the internal viewer return properly.

Has anyone determined the cause/resolution for this issue?
