Hi,

I am trying to invoke James Mailbox Copier method which copies mails from
MySQL database to a jcr-mailboxmanager i.e., file system. After making a
call to this method OpenJPA is throwing error below, Please let me know if I
am missing any library.
**********
Problem invoking copy: java.rmi.UnmarshalException: Error unmarshaling
return; nested exception is:
java.lang.ClassNotFoundException:
org.apache.openjpa.persistence.InvalidStateException (no security manager :
RMI class loader disabled)
**********

I appreciate your help on this.

Thanks, Sai
