JSP and JPO Compilation
When an app page (JSP) is first accessed, the JVM in the app server compiles it. To improve performance for the first user, you should pre-compile all the pages, as well as all the JPOs in the database.
All JPOs and JSPs should be compiled using the same version of the JDK that the app server will use. Use the Collaboration and Approvals utility to run the MQL compile command to ensure that the same JDK is used. To compile JPOs, use the following MQL command:
MQL<> compile prog * force update;
