Hello,

i have read that an EJB can auto generate his primarykey, i think that is the only correct way for using a database.

when i take a normal attribute as PK i can not change this attribute and create self a PK is not so good :(.

but the following idea will not use with JBoss :( (what does it wrong?)

Idea:

- EntityBean
public Object ejbCreate(.....)
{
...
return null;
}

- BeanHome
public findByPrimaryKey(Object primaryKey)

- ejb-jar
<prim-key-class>java.lang.Object</prim-key-class>



error:

20:45:56,153 ERROR [EjbModule] Starting failed
org.jboss.deployment.DeploymentException: Error while creating table; - nested throwable: (java.sql.SQLException: Column not found: ) in stat
ement [CREATE TABLE BENUTZER (login VARCHAR(256), passwort VARCHAR(256), type VARCHAR(256), timestamp DATE, status VARCHAR(256), CONSTRAINT P
K_BENUTZER PRIMARY KEY ())])
at org.jboss.ejb.plugins.cmp.jdbc.JDBCStartCommand.createTable(JDBCStartCommand.java:190)



thanks for help
bye Peter
