hi there .. im running into a strange problem while deploying an
entity bean ..

these are my xdoclet tags:

* @ejb.finder
* query = "SELECT object(o) FROM User o WHERE o.login=?1 AND
o.password=?2"
* signature = "com.ikatomi.im.user.ejb.UserLocal
findByUsernameAndPassword(java.lang.String login,java.lang.String
password)"
*
* @jboss.query
* query = "SELECT object(o) FROM User o WHERE o.login=?1 AND
o.password=?2"
* signature = "com.ikatomi.im.user.ejb.UserLocal
findByUsernameAndPassword(java.lang.String login,java.lang.String
password)"
*/

and this is the error jboss is throwing ..

17:35:48,147 ERROR [EntityContainer] Starting failed
jboss.j2ee:jndiName=UserLocal,service=EJB

i have to add that i can use the findByPrimaryKey method without any
probems which means that i made a mistake in my finder method ...
but i dont know why it throws a NullPointerException

greetings from berlin

Difficult to diagnose as the xdoclets look okay to me. Have you
had a peek at the META-INF/jbosscmp-jdbc.xml file? It should
contain something like this:

<query>
<query-method>
<method-name>findByUsernameAndPassword</method-name>
<method-params>
<method-param>java.lang.String</method-param>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<jboss-ql><![CDATA[SELECT object(o) FROM User o WHERE o.login=?1 AND
o.password=?2]]></jboss-ql>

</query>

Only other thing I could suggest (even though it should not make
a difference, technically speaking) is to add spaces before and
after the equals sign. I seem to recall having problems in the
past with parsers which required white-space between tokens...
