Thx for the reply :) > Does your application have any CMP 2.1 Entity beans? Not sure whether is CMP 2.1 and how should I verify ? I coded it byfollowing a tutorial of EJB3 . I enclose the source of the EntityBEan Material.java as a reference at end of msg
> What geronimo version are you using? I am using geronimo 2.1 on ubuntu , below is the openejb-jar.xml & persistence.xml for your reference FYI, my program consists of 2 entity bean, Material & MaterialType. Initially I try to use the dbpool in geronimo for the db connection but it seems like does not work , therefore , I hardcoded the driver name , server name in the coding. Initially there is tag <jta-source> in the openejb-jar.xml but it prompt me for error under eclipse GEP 2.1 snapshot plugin, and Ihave remove it out.
