1. Re: link -> java:/DefaultDS
adrian.brock Oct 10, 2003 5:41 AM (in response to klyall)Because you haven't specifed the jndi name for the
resource manager in jboss.xml
ejb-jar.xml
<resource-ref>
<res-ref-name>jdbc/DataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
jboss.xml
<enterprise-beans>
<ejb-name>UnshareableStateful</ejb-name>
<resource-ref>
<res-ref-name>jdbc/DataSource</res-ref-name>
<resource-name>RealDS</resource-name>
</resource-ref>
</enterprise-beans>
<resource-managers>
<resource-manager res-class="">
<res-name>RealDS</res-name>
<res-jndi-name>java:/OracleDS</res-jndi-name>
</resource-manager>
</resource-managers> -
2. Re: link -> java:/DefaultDS
klyall Oct 10, 2003 7:35 AM (in response to klyall)Thanks for that, I have now got the "link ->" showing correctly.
I have still not fixed my overall problem though as I think my JBoss/EJB config knowledge is not too good.
I have an application with several CMP entity beans that I want to use the OracleDS.
Therefore I have specified defaults in jbosscmp-jdbc.xml as:
java:/OracleDS
<datasource-mapping>Oracle8</datasource-mapping>
<create-table>false</create-table>
<remove-table>false</remove-table>
I also have a resource manager in jboss.xml to map the JNDI name to resource name:
<resource-managers>
<resource-manager>
<res-name>OracleDS</res-name>
<res-jndi-name>java:OracleDS</res-jndi-name>
</resource-manager>
</resource-managers>
Do I have to specify for each CMP Bean something in ejbjar.xml and/or in jbosscmp-jdbc.xml to link the CMP Bean to the specific datasource or is adding a resource-ref for each CMP Bean not required.
I can't see where the application server makes the connection between a CMP Bean and its datasource.
Thanks in advance for any help. -
3. Re: link -> java:/DefaultDS
adrian.brock Oct 10, 2003 7:42 AM (in response to klyall)You do not need to configure a <resource-ref> if you have
configured it in jbosscmp-jdbc.xml
The <resource-ref> allows you to lookup("java:comp/env/jdbc/DataSoruce");

4. Re: link -> java:/DefaultDS
klyall Oct 10, 2003 7:55 AM (in response to klyall)Thanks again Adrian.
I thought the resource-ref on the CMP Bean looked superfluous.
In my application I have several CMP entity beans and all but one are accessing the OracleDS and one rogue CMP bean is accessing the DefaultDS.
How does a CMP Beans know which datasource to use?
I have looked at the jbosscmp-jdbc.xml and ejbjar.xml and can't see any differences between the CMP Bean definitions.
Is there a way I can debug this problem?
