Hello. I don't know whether this can be considered a duplicate of
GLASSFISHPLUGINS-319, although it seems very similar. I have a Dynamic Web Project that includes another JPA Project in which I only define the database mappings (entities) and the persistence.xml definitions (this is because these are common to more than one project). Prior to Glassfish Eclipse plugin 188.8.131.52010180926 everything was fine, but since I updated Eclipse with this version of the plugin, every time I try to deploy the Dynamic Web Project, Eclipse complains that it doesn't find the first invoked entity of the JPA entity list. It seems as if the JAR file created by the plugin from the JPA Project is not in the classpath of the web application.
This happens with every embedded project as well. I have tried with a plain Java project being embedded in another, and the result is the same.
