Hi all,
I have tried to strip down the information to the bare essential
information for clarity and brevity.
Again any Help is greatly appreciated.
Ron.
The basic problem is that I am getting an null DataObjects
object back from jndi on JBoss when using a lookup from
an ejb.
ModelService is my EJB Session Bean.
I have a web service using apache axis that
accesses a local Service Broker that does a
lookup of the ejb bean using the ModelService
Name:
Object objRef = context.lookup("ejb/sms3/ModelService");
*** In the ejbCreate of ModelService, I create a
ModelServiceDao object. In the ModelServiceDao
constructor I create a CastorHelper object. In
Castor Helper constructor I try to create a
DataObjects using a lookup as follows:
Context compEnv = (Context) iniCtx.lookup("java:comp/env");
_jdo = (DataObjects) compEnv.lookup("jdo/modelJDO");
jdo/modelJDO is referenced in the ejb-jar as follows
- <resource-ref>
<res-ref-name>jdo/modelJDO</res-ref-name>
<res-type>org.exolab.castor.jdo.DataObjects</res-type>
<res-auth>Container</res-auth>
</resource-ref>
*** jdo/modelJDO is mapped to a resourceManager in JBoss.xml under the name
CastorModelJDO.
CastorModelJDO refers to the resource jndi name
Java:/castorModel that is defined in an mbean.
- <resource-ref>
<res-ref-name>jdo/modelJDO</res-ref-name>
<resource-name>CastorModelJDO</resource-name>
</resource-ref>
- <resource-manager res-class="org.jboss.ejb.deployment.CastorJDOResource"> ******* is
this the right class????
<res-name>CastorModelJDO</res-name>
<res-jndi-name>java:/castorModel</res-jndi-name>
</resource-manager>
*** Here is the binding information for jdo/modelJDO
15:35:38,438 INFO [STDOUT] modelJDO: javax.naming.LinkRef:Reference Class Name:
javax.naming.LinkRef
Type: LinkAddress
Content: java:/castorModel
*** In the MBean I define a castorJDO resource under the jndi name java:/castorModel
as follows:
<mbean code="org.jboss.jdo.castor.CastorJDOImpl" name="jboss:service=CastorJDO">
<attribute name="Configuration">file:../server/sms3/conf/database.xml</attribute>
<attribute name="JndiName">java:/castorModel</attribute>
...</mbean>
*** in the database.xml file I reference a MSSQL
DataSource as follows:
<jndi name="java:/MSSQLXaDS"/>
*** I have registered the MSSQL datasource in an
MBean as:
<mbean code="org.jboss.resource.connectionmanager.XATxConnectionManager"
name="jboss.jca:service=XATxCM,name=MSSQLXaDS">
...</mbean>
So what's my problem (technically speaking :)
I hope this is more clear and concise.
Thanks again,
Ron
