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, RAttrUniqueValue,
AbstractVirAttr, Membership, TaskExec, SyncopeConf, Report, RAttr,
AbstractExec, SyncopeLogger, USchema, MAttr, PasswordPolicy, RSchema,
MSchema, MAttrValue, MAttrUniqueValue, AbstractAttr, AbstractDerSchema,
AbstractVirSchema, UAttr, AccountPolicy, RAttrValue, UAttrValue,
ReportExec, SyncopeUser, Notification, ConnInstance, AbstractDerAttr,
AbstractAttrValue, SyncopeRole, SyncPolicy, Policy,
ReportletConfInstance, Task, UAttrUniqueValue, Entitlement,
SchemaMapping, UserRequest]

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?
Thanks for your support.
Regards.
