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.

means that OpenJPA could not find any metadata for "class

containing your metadata is not in your CLASSPATH, or if your metadata files
are not named properly. See the documentation on metadata placement for more
information.

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>

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.
