I get this exception I don't know how to solve. I am pretty sure it is a dumb mistake, but I can't see it.

I get the same error extending EntityQuery too.

Any ideas?

TIA.

Remove the backslash from 


<core:init debug="true" jndi-pattern="upcn-ear/\#{ejbName}/local"/>

to 


<core:init debug="true" jndi-pattern="upcn-ear/#{ejbName}/local"/>
