I have an application developed using struts and the application is deployed on Oracle 9iAS on UNIX platform. When I configure the Oracle 9iAS to run multiple procesess (more than 1 JVM's) then if i click on a menu item which point to a JSP then session becomes null. While if i click on drop down menu items which point to action mappings then the application works fine. I have noticed one more thing that when i click on the link after which the session becomes null , URL is rewritten to include session id while when i use menu items which work fine the URL is not rewritten. This problem occurs only when the Orcale 9iAS is configured to run multiple processes. When its configured to run only one process, this problem does not appear. Does anyone have a clue as to why its happening or what might be the solution.. thanks..
