Before reading this entry (always a friendly warning first!), please read about my two blog entries that I posted earlier. This entry is kind of closure to my previous topic “Jolt Session Pooling”. If you still have decided to read this one, you cant complain about not able to understand this one….
In our last blog entry, we talked about Jolt Session Pooling. As I stated earlier, Jolt Session Pooling is enabled by default in Tools Version 8.48 and later. Considering this new feature(!), there are some things that are changed due to this parameter single change starting with Tools 8.48 and later….
Also, we talked about the sevlets (like psc, psp etc) that are having ‘definitions” in the web.xml file (under DOMAIN/PORTAL/WEB-INF directory). So, back to our main point.. why JoltPooling needs to be disabled for all the servlet entries in the web.xml file to resolve the “download to excel” button to work… Probably you have guessed it already.
The key point here is, when Jolt Session Pooling is enabled, the session is shared across all the servlets. The existing sessions are shared across multiple servlets within weblogic server. This is supposed to be provide good performance results. There are no dedicated sessions. As of now, I know some of the effects of this change in 8.48 environment:
- “Download to Excel” button not working
- Tuxedo is unable to list the online users on the system
- “View Attachment” is not working
If you know anything else due to this “Jolt Session Pooling” enabled option causing in Peoplesoft, please write on the comment below for me to know and learn. My policy is to share the knowledge and feel free to learn. 
To know more about Jolt and Weblogic, I would recommend you to read the BEA documentation about “Using BEA Jolt with BEA Weblogic Server” Guide. I am going to write some new things going forward… One of the m is about my favorite. Inter Process Communication in the Unix System and Peoplesoft.
