    AutoIncrement Primary Key in CMP

    Mukti furtado Newbie

      Hello,

      I want to automatically increment the primary key field in the database(MySql) in a CMP bean. I have written the following lines in the jbosscmp-jdbc.xml

      <unknown-pk>
      <unknown-pk-class>java.lang.Integer</unknown-pk-class>
      <field-name>userID</field-name>
      <column-name>userID</column-name>
      <jdbc-type>INTEGER</jdbc-type>
      <sql-type>INT(11)</sql-type>
      <auto-increment/>
      </unknown-pk>
      <entity-command name="mysql-get-generated-keys"/>

      But when i get a Nullpointer exception when i try to insert a record through my CMP.
      Can you please tell me where i am going wrong
      Thanks
