Hello,
I am having trouble getting
JBoss to create primary keys with the UUIDKeyGeneratorFactory (I tried with MySQL generate keys with no luck also). I get the following exception when I try to create a new Share bean:
javax.ejb.CreateException: Could not create entity:java.sql.SQLException: Column 'id' cannot be null at org.jboss.ejb.plugins.cmp.jdbc.JDBCAbstractCreateCommand.performInsert(JDBCAbstractCreateCommand.java:327)
If I explictly call the setId() method in ejbCreate everything works fine and row is inserted in my table... any help would be much appreciated. I have included relevant files below:
ShareBean.java
package tutorial.ejb;
import java.rmi.RemoteException;
import java.util.Date;
import javax.ejb.EJBException;
import javax.ejb.EntityBean;
import javax.ejb.EntityContext;
import javax.ejb.RemoveException;
