NullPointerException during SAR Service deployment

Hi all,

Still continuing to test/verify how to use mbean...

Here is now how I implement the bind/rebind:
<code>
private void rebind() throws NamingException

{ InitialContext rootCtx = new InitialContext(); Name fullName = rootCtx.getNameParser("").parse(getFullJndiName()); ServiceName servName=ServiceName.parse(getFullJndiName()); WritableServiceBasedNamingStore.pushOwner(servName); try { logger.info("fullName=" + fullName+" -> rebind ..."); org.jboss.util.naming.NonSerializableFactory.rebind(fullName, sHelper, true); logger.info("fullName=" + fullName+" -> rebind ok"); } catch(NamingException ex) { ex.printStackTrace(); throw ex; }

finally

{ WritableServiceBasedNamingStore.popOwner(); }

}
</code>

Like that, I don't have the 'context is read only' issue any more.
But I get another exception...

I use a jboss-service.xml file, containing the following:

<mbean name="mid.services.dao:service=AddressDAOMBean"
code="be.post.common.servicebinder.DaoJndiBinder">
<attribute name="JndiName">be.post.mid.dao.AddressDAO</attribute>
<attribute name="DataSourceJndiName">java:MIDCoreOracleDS</attribute>
<attribute name="InterfaceClass">be.post.mid.dao.AddressDAO</attribute>
<attribute name="ImplementationClass">be.post.mid.dao.oracle.AddressOracle</attribute>
</mbean>

I could identify the line giving the exception:

// add the service name to runtime bindings management service, which on stop releases the services.
final Set<ServiceName> duBindingReferences = (Set<ServiceName> getServiceRegistry().getService(JndiNamingDependencyProcessor.serviceName(deploymentUnitServiceName)).getValue();

But what is the root cause of it?

any suggestion?

thanks a lot...
