X-Application Version: 3.1.3

Hello,

I get this error randomly: “SessionContext is not locked”.
This happens when I am using a directcommand as a query.

Note:
I am still using version 3.1.3. Because my java IDE doesn’t support Tomcat v. 4.1.x.

Here is the stack trace:

Hope you can see something from the stacktrace.
Best regards

Hello,

The error occurs when the trace class “TraceInfo” is invoked. Did you enable tracing? If yes, you could disable the tracing and check whether the error still occurs or the problem is solved.

Could you post the JSP with your directcommand to the community? Then, we can try to reproduce the problem since it looks like a bug of the trace functionalty.

Many thanks.

Bye,
Christian.

Hello Christian,
Thank you very much for the reply.
You were right! I just changed the DIAGNOSIS parameter to “false” and then it works. But a strange thing is that I have had this project running for a long time with this parameter set to “true” without these problems.

About sending the page:
This page we are talking about displays results from a query. It can be invoked from 3 other pages (which set the query parameters).
And all the pages have beans that communicate with a DB2 database.
There is also modifications to tags because of plugins.
So I think it will be difficult to reproduce the problem since this page has become very complex.

Best regards
Eagle
