I've also got this problem. Did either of you guys discover what was wrong, or find a workaround?
I have an EJB Singleton packaged in a JAR, within an EAR. When it deploys, it says the EJB is bound to:
"java:app/store-core-2011.1.2-SNAPSHOT/StoreFront"
"java:app/store-core-2011.1.2-SNAPSHOT/StoreFront!uk.co.magus.jam.store.core.Store"
"java:module/StoreFront"
"java:module/StoreFront!uk.co.magus.jam.store.core.Store"
"java:global/store-ear-2011.1.2-SNAPSHOT/store-core-2011.1.2-SNAPSHOT/StoreFront!uk.co.magus.jam.store.core.Store"
"java:global/store-ear-2011.1.2-SNAPSHOT/store-core-2011.1.2-SNAPSHOT/StoreFront"
I try to look it up via JNDI from code within a JAR within another deployed EAR. Only the last entry ({{"java:global/store-ear-2011.1.2-SNAPSHOT/store-core-2011.1.2-SNAPSHOT/StoreFront"}}) can actually be found, and when I try to cast the resulting object to the actual class, I get the following exception:
Caused by: java.lang.ClassCastException: uk.co.magus.jam.store.core.StoreFront$$$view1 cannot be cast to uk.co.magus.jam.store.core.Store
