Hi,
 
We are struck with 2 problems:
 
    1. We have written orm.xml file for our application and we are getting the following exception. We are also attaching our orm.xml and persistance.xml files for your reference.

    2. To make an entity readonly in an application(described below).
 
   
    Please help us in resolving these two problems as we have struck with these two problems. We are not able to findout where exactly is the mistake in our configurations.
 
Thanks,
Praveen Kumar.

Hello Patrick Linskey,
 
We are facing the following problem in our project.
 
<0.9.7-incubating fatal user error> org.apache.openjpa.persistence.InvalidStateException: Encountered unmanaged object "com.vormetric.server.dao.user.RoleDTO@51ac51ac" in persistent field "com.vormetric.server.dao.user.UserDTO.roles<element:class com.vormetric.server.dao.user.RoleDTO>" of managed object "com.vormetric.server.dao.user.UserDTO@4f164f16" during flush.  However, this field does not allow cascade persist.  You cannot flush unmanaged objects.

We are having 2 entity classes UserDTO and RoleDTO files. We want the RoleDTO entity to be readonly.
So Please help us to make an entity readonly in an application.
 
The following is the tag in our existing hibernate mapping file. We are replacing the hibernate code with OpenJPA code
 
<hibernate-mapping>
    <class name="com.vormetric.server.dao.user.RoleDTO" table="CGSS_ROLE">
  <cache usage="read-only"/>
So please help us as soon as possible, to make an entity readonly.
 
Thanks,
Praveen Kumar.
