I realize this is more of an eclipse related question. But was hoping someone here has already tackled this.
I have some DAO classes that user OpenJPA. This is packaged as a jar and I can use the jar in a regular Java application to connect and query the database. I then created an Eclipse RCP plugin frmo this jar file. When I launch the plugin inside an RCP application I get a Caused by: <openjpa-1.0.0-r420667:568756 fatal user error> org.apache.openjpa.persistence.ArgumentException: A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName property. at org.apache.openjpa.jdbc.schema.DataSourceFactory.newDataSource(DataSourceFactory.java:72) at org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.createConnectionFactory(JDBCConfigurationImpl.java:803) at org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.getDBDictionaryInstance(JDBCConfigurationImpl.java:568) Looks like OpenJPA cannot locate the persistence.xml file. Seems like eclipse class loading issues. If someone's already figured out how to get this to work I'd appreciate any pointers. Thanks
