Failure in the Compilation of BPEL Generated Classes From 11g in 12c

Compilation of the generated BPEL classes from 11g fails in 12c if the class path setting is incorrect. Custom composites should have the dependent jars under BpelcClasspath to ensure that the composites are deployed successfully.

To resolve the issue:

1. Go to Enterprise Manager Console and log in as weblogic user.
2. On the left pane, expand Weblogic Domain, select <WLS_DOMAIN> right-click System MBeans Browser.
3. Go to Application Defined MBeans, select oracle.as.soainfra.config, click Server:<SOA_SERVER>, select BPELConfig, and then click bpel.
4. Under the Attributes column, click BpelcClasspath and take a backup of those values.
5. Add the following jar file paths separated by a colon, and save the details.

   $MW_HOME/oracle_common/modules/oracle.jps/jps-api.jar:/$OIM_HOME/server/client
   /oimclient.jar
