JBoss throws NullPointerException when deploying ejb

[cummings]

Greetings -

After days of great pain trying to build and deploy a simple test app (one each: jsp, servlet, entity bean (TWUserRole) and session bean (TWManageUserRole) I have a new problem - JBoss is throwing a NullPointerException when deploying my ejbs. Any suggestions? I cannot tell anything meaningful from the exception.

Greetings -

I found the exact same exception in a posting to Datasource Configuration, but there were no replies. Posting dated from Sept. 22, '02. Hope someone in this group has an answer. Interestingly, the problem was with MySql, whereas I'm using DB2, although the exception is the same.

Any suggestions?

Thanks ...

Do you have a data-source configured in ur jbosscmp-jdbc.xml?
I looked in the code based on ur stacktrace and this is where it breaks
con = dataSource.getConnection();

so it probably doesnt get the DataSource from ur Config file?

Post the appropriate section of ur jbosscmp-jdbc.xml file.

Thanks - here's the info:

Here's db2-service.xml, which I've placed in the deploy directory:

java:/jdbc:/SAMPLE


<config-property name="ConnectionURL" type="java.lang.String">jdbc:db2:SAMPLE</config-property>
<config-property name="DriverClass" type="java.lang.String">COM.ibm.db2.jdbc.app.DB2Driver</config-property>

And here's my entire jbosscmp-jdbc.xml file:

<jbosscmp-jdbc>

java:/jdbc:/SAMPLE
<datasource-mapping>DB2</datasource-mapping>

<enterprise-beans>

<ejb-name>TWUserRole</ejb-name>
<create-table>true</create-table>
<remove-table>true</remove-table>
<table-name>TWUSERROLE</table-name>
<cmp-field>
<field-name>id</field-name>
<column-name>USERROLEID</column-name>
</cmp-field>
<cmp-field>
<field-name>name</field-name>
<column-name>NAME</column-name>
</cmp-field>
<cmp-field>
<field-name>userId</field-name>
<column-name>USER_USERID</column-name>
</cmp-field>

</enterprise-beans>
<dependent-value-classes>
</dependent-value-classes>
</jbosscmp-jdbc>

Is this the whole db2-service file? There should be a lot more information. You can find service files in the jboss-3.0.4/docs/examples/jca dir. Just change the user, password and the database. You also have to copy the <application-policy> part to you login-config.xml file (server/default/conf dir). And dont't forget to copy the driver to your server/default/lib dir.

Thanks for the responses on this. Problem is now solved - here's the info for the benefit of others with this problem.

First, the xml for db2-service.xml was an excerpt - I am using the entire file from the examples.

I made the following changes to my erroneous entries:

1. standardjbosscmp.xml
java:/DB2DS
<datasource-mapping>DB2</datasource-mapping>

2. db2-service.xml
DB2DS

3. .ant.properties
datasource.name=java:/DB2DS

Now I'm getting another problem related to a custom finder method, but I'll put up a new posting on that.

Cheers
