If you intended for "class test.XMLDatatypeSupportTestEntity" to be persistence-capable, then this means that OpenJPA could not find any metadata for "class test.XMLDatatypeSupportTestEntity". This can happen if the directory 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.

However if the target is specified, the enhancement will occur, E.g.
