    Datasource and CMP entity bean

      Hi,

      I wrote a simple entity bean that would use CMP. I'm using Oracle JDBC driver, and the bean works OK under JBoss 3.2.3. In Jboss 4.0, it seem to use the default DataSource and not the one I'm trying to specify.


      The deployment descriptors are:

      ejb.xml:

      <ejb-jar>
 <display-name>testModule</display-name>
 <enterprise-beans>
 <entity>
 <display-name>Enterprise1BeanName</display-name>
 <ejb-name>Enterprise1BeanName</ejb-name>
 <home>Enterprise1Home</home>
 <remote>Enterprise1Remote</remote>
 <ejb-class>Enterprise1Bean</ejb-class>
 <persistence-type>Container</persistence-type>
 <prim-key-class>java.lang.String</prim-key-class>
 <reentrant>False</reentrant>
 <cmp-field>
 <field-name>id</field-name>
 </cmp-field>
 <cmp-field>
 <field-name>payload</field-name>
 </cmp-field>
 <primkey-field>id</primkey-field>
 </entity>
 </enterprise-beans>
 <assembly-descriptor>
 <container-transaction>
 <method>
 <ejb-name>Enterprise1BeanName</ejb-name>
 <method-name>*</method-name>
 </method>
 <trans-attribute>Required</trans-attribute>
 </container-transaction>
 </assembly-descriptor>
</ejb-jar>


      jaws.xml: 

      <jaws>
 <datasource>testDataSource</datasource>
 <type-mapping>Oracle8</type-mapping>
 <enterprise-beans>
 <entity>
 <ejb-name>Enterprise1BeanName</ejb-name>
 <cmp-field>
 <field-name>id</field-name>
 <column-name>ID</column-name>
 </cmp-field>
 <cmp-field>
 <field-name>payload</field-name>
 <column-name>PAYLOAD</column-name>
 </cmp-field>
 <table-name>EJBTEST</table-name>
 </entity>
 </enterprise-beans>
</jaws>


      jboss.xml: 

      <jboss>
 <enterprise-beans>
 <entity>
 <ejb-name>Enterprise1BeanName</ejb-name>
 <jndi-name>Enterprise1JNDI</jndi-name>
 </entity>
 </enterprise-beans>
</jboss>


      "testDataSource" is configured in oracle-ds.xml and jdbc driver's jar file is in /lib directory.

      Could anyone help?

      Thanks,

      Peter

          Perhaps it is because you forgot to tell whisc datasource you use in ejb.xml. Hope this helps.

            defkewl:

            I tried to add <resource-ref> to jboss.xml and ejb.xml but it didn't help.

            But then I read it on the Net, that I should use jbosscmp-jdbc.xml instead of jaws.xml.

            So I created one

            <?xml version="1.0" encoding="UTF-8"?>
<jbosscmp-jdbc>
 <defaults>
 <datasource>java:/testDataSource</datasource>
 <type-mapping>Oracle8</type-mapping>

 <debug>true</debug>
 <create-table>true</create-table>
 <remove-table>false</remove-table>
 <read-only>false</read-only>
 <time-out>0</time-out>
 <select-for-update>false</select-for-update>
 <pk-constraint>true</pk-constraint>
 <relation-mapping-style>foreign-key</relation-mapping-style>
 <read-ahead>
 <strategy>on-load</strategy>
 <page-size>500</page-size>
 <eager-load-group>group name</eager-load-group>
 </read-ahead>
 </defaults>
 <enterprise-beans>
 <entity>
 <ejb-name>Enterprise1BeanName</ejb-name>
 <table-name>EJBTEST</table-name>

 <cmp-field>
 <field-name>id</field-name>
 <column-name>ID</column-name>
 </cmp-field>
 <cmp-field>
 <field-name>payload</field-name>
 <column-name>PAYLOAD</column-name>
 </cmp-field>

 </entity>
 </enterprise-beans>
</jbosscmp-jdbc>


            and then the CMP worked.
