Hi all,
I've found this guide [1] about using OenJPA 2.2.0 and JBoss 7.1: I
had some minor issues (already reported on that page) easily solved,
but then I came to this exception, thrown at every JPA query:
<openjpa-2.2.0-r422266:1244990 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: An error occurred
while parsing the query filter "SELECT e FROM ExternalResource e".
Error message: The name "ExternalResource" is not a recognized entity
or identifier. Perhaps you meant ExternalResource, which is a close
match. Known entity names: [ExternalResource, AbstractSchema,

Report, RAttr, AbstractExec, SyncopeLogger, USchema, MAttr,
PasswordPolicy, RSchema, MSchema, MAttrValue, MAttrUniqueValue,

I've taken a look at JPQLExpressionBuilder.getClassMetaData() and it
seems to me that the problem might lie in some hidden Classloader
thing in JBoss: any hint?
I've attached a patch to
https://issues.apache.org/jira/browse/OPENJPA-2229 that should fix this:
WDYT?
Regards.
