ApplicationPoolException: JBO-30006: The cookie for session

Question

Hi
Presently we are using the followings s/w for our product development:
1.     JDeveloper 11g (11.1.1.0.2) - yet to migrate to JDev 11g R1 (11.1.1.1.0)
2.     Weblogic 10.3.0
3.     Target Browser Client is IE7 – and to extend to FF3+
Now we have completed few of the modules and is in the process of moving to Customers Beta Env. During our testing we are getting some sort of JBO errors (server log) and the browser displays ‘Cancel or Retry’ message.
A portion of error message from the stack trace has been pasted below
oracle.jbo.common.ampool.ApplicationPoolException: JBO-30006: The cookie for session 0K5ZKVDL7wNcJ2qXTkQhjCQvq0sJSykgnV8P0WQMvNqdbF9QdThk!1335475191!1247101864354 and application 378381615_1_PcmsSysDataControl_$beandc$_ is not a valid handle for application pool, InternalDCAMs. The cookie may not be used to access this pool instance.

at oracle.adf.model.bc4j.DCJboDataControl.releaseApplicationModule(DCJboDataControl.java:2324)
The present scenario:
1.     ADFModel1.jar - An ADF Model Project contains a set of views to be used across multiple Model projects by Importing Business Components.
2.     ADFModel2.jar - This project uses ADFBC import from the above model project – ADFModel1.jar
All the view implementations are available here as the Core Model
3.     ADFModel3.jar - Imports ADFModel2.jar – used as a Customization layer (refer error message above - PcmsSysDataControl)
4.     ViewController.war - Contains all the JSPX, Page Defs, Html, JS, CSS, Images
Both ADFModel3.jar and ViewController projects are under a separate .jws (Application Workspace) and running as a separate application. Similar way all other applications have been modeled.
Both ADFModel2 and ADFModel3 has the DataSource Names defined. Please help us to resolve this issue.
If you need any more info, please let me know

Answer 1

have you ever solved the problem? I have a similar issue on Linux RedHat with a load-balanced cluster of Tomcat. The strange thing is that only one of the servlets always issues the problem. The incriminated app module is created with "Configuration.createRootApplicationModule..." and released at the end. I have a similar servlet that creates the same app module with the same command and has no problems.
The ADF Team, what does it say about?
Thanks
