reference external JAR's

[kometen]

Hi.

I have installed JBoss 2.4.4 and is trying to implement the cabin- and travelagent- examples in Richard Monson-Haefel's Enterprise JavaBeans.

Running the CabinEJB goes fine, I'm able to connect to postgresql (ver. 7.1 and 7.2) and insert the records. The problem is when I try to let the travelagent bean to talk to the cabin bean. The error-message from the JBoss -console is:

[INFO,Default] Got context
[ERROR,TravelAgentEJB] TRANSACTION ROLLBACK EXCEPTION:

The ejb-jar.xml is:

<ejb-jar>
<enterprise-beans>

TravelAgent Session Bean
<display-name>TravelAgent</display-name>
<ejb-name>TravelAgentEJB</ejb-name>
no.gnomeit.travelagent.TravelAgentHomeRemote
no.gnomeit.travelagent.TravelAgentRemote
<ejb-class>no.gnomeit.travelagent.TravelAgentBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<ejb-ref>
<ejb-ref-name>ejb/CabinEJB</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
no.gnomeit.cabin.CabinHomeRemote
no.gnomeit.cabin.CabinRemote
</ejb-ref>

</enterprise-beans>

<assembly-descriptor>
...
</assembly-descriptor>
</ejb-jar>

The jboss-xml looks like:


<enterprise-beans>

<ejb-name>TravelAgentEJB</ejb-name>
<ejb-ref>
<ejb-ref-name>ejb/CabinEJB</ejb-ref-name>
<jndi-name>CabinBean</jndi-name>
</ejb-ref>

</enterprise-beans>


TravelAgentBean.java (parts of):

public String [] listCabins(int shipId, int bedCount) {
try {
// Get a naming context
InitialContext jndiContext = new InitialContext();
System.out.println("Got context");

// Get a reference to the CabinBean bean
Object obj = jndiContext.lookup("java:comp/env/ejb/CabinEJB");
System.out.println("Got reference");

CabinHomeRemote home = (CabinHomeRemote)
PortableRemoteObject.narrow(obj, CabinHomeRemote.class);


I have changed the com.titan with no.gnomeit, but this should only be cosmetic.

I have deployed the travelagent.jar file with the CabinHome.class and CabinHomeRemote.class as stated in the jboss-doc. The jar is (according to the jboss-console) correct.

Am I doing this right?
