We have a persistence.xml with multiple datasources and entity jars. With the latest JBoss Tools, we just started getting a validation error on the <jar-file> tags which contain relative paths (e.g. ../lib/my-entity-file.jar) as shown here: http://stackoverflow.com/questions/4073635/sharing-a-persistence-unit-across-components-in-a-ear-file

This didn't happen in earlier versions of Eclipse/JBoss tools, including Kepler M7 + JBoss Tools 4.1.Alpha1.

If there is a better way to specify picking up this jar file, please indicate.
