RE: [JBoss-user] use of <auto-increment/> in 3.2 CMP

[Brian T. <to...@di...>]

Ah, I found it.  It was not found with the search terms that I was =
using.
But now I'm getting a ClassCastException, seems that the return type =
from the
driver is an Integer, and I'd like to use a Long, since there are a ton =
of
files already standardized on that.

So I'm wondering, is there any way to use a java.lang.Long as the PK =
while
using MySQL?  I'm generating the descriptor using:

 * @jboss.unknown-pk
 *    class=3D"java.lang.Long"
 *    column-name=3D"id"
 *    jdbc-type=3D"BIGINT"
 *    sql-type=3D"BIGINT(20)"
 * @jboss:entity-command name=3D"mysql-get-generated-keys"

and the result is:

<entity>
	...
         <cmp-field>
            <field-name>id</field-name>

			<auto-increment/>
        </cmp-field>

	  <!-- merge point: jbosscmp-jdbc-load-{0}.xml -->

	<unknown-pk>
		<unknown-pk-class>java.lang.Long</unknown-pk-class>
		<column-name>id</column-name>
		<jdbc-type>BIGINT</jdbc-type>
		<sql-type>BIGINT</sql-type>
	</unknown-pk>
	<entity-command name=3D"mysql-get-generated-keys">
	</entity-command>
</entity>

Thanks for your efforts with all this Alex!
