Error when starting Oracle Identity Manager Design Console (11.1.2): java.lang.NoClassDefFoundError: javax/ejb/CreateException

After a new installation of  Oracle Identity Manager (OIM) I tried to start the Design Console and all I got was the following error:

[oim@linux designconsole]$ ./xlclient.sh

It turns out I missed one step in installation instruction. Fix:

• Change to MW_HOME/wlserver_10.3/server/lib directory
• Set JAVA_HOME
• Execute 

java -jar wljarbuilder.jar
.
.
.
Created new jar file: /oracle/oim0/mwh/wlserver_10.3/server/lib/wlfullclient.jar

• Copy wljarbuilder.jar to $OIM_ORACLE_HOME/designconsole/ext

After that it works.
