Issue: Errors about missing JAR files are generated when you launch EPM System Configurator after installing several EPM System products, and EPM System Configurator closes in about 30 seconds.
Solution: Error messages about missing JAR files indicate that the installation is incomplete. Check for these messages
If you see error messages about missing JAR files or errors related to oracle_common jars, then the WebLogic installation is incomplete.
Look in the ohs and oracle_common subfolders of MIDDLEWARE_HOME. If ohs contains only one or two subfolders, or if oracle_common is empty, then the Oracle HTTP Server, WebLogic, or Application developer installation is incomplete. Check the minimum swap space on the system, which must be at least 512 MB.
Review the log files to find more specific reasons for the failure. Start by reviewing the OUI logs in the Central Inventory logs folder. See Central Inventory Logs.
