Hello everybody, I am currently writing a custom connector to retrieve information from a database. Because the mediators to do so does not fit my needs, I am using a custom Java class which is currently implemented to retrieve a DataSource via the JNDI name I configured in the ESB interface. That works nicely :)
But then, for maintenance purpose, I would like to use JPA (preferably, the OpenJPA implementation :)) but it is like the persistence.xml is not even read. :( My libraries are placed in the lib/ directory in the generated zip of my connector and I don't have any problem using the classes of OpenJPA. Actually, just this error message appears: 1 INFO [PassThroughMessageProcessor-313] openjpa.Runtime - Starting OpenJPA 2.4.0 org.apache.openjpa.persistence.ArgumentException: The persistence provi der is attempting to use properties in the persistence.xml file to resolve the data source. A Java Database Connectivity (JDBC) driver or data source class name must be specified in the openjpa.ConnectionDriverName or javax.persistence.jdbc.driver property. The following properties are available in the configuration: "org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl@442ce698". In the persistence.xml, you have the following content : <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";> <persistence-unit name="my-pu" transaction-type="RESOURCE_LOCAL"> <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> <jta-data-source>jdbc/MyDataSource</jta-data-source> </persistence-unit> </persistence> Is there some hidden magic to make it work? Thank you :) Regards, Thomas
