Thanks for your quick reply.

Your suggestion has been implemented. It still doesn't work, but it might be a 
configuration problem.

Here is the configuration before the implementation (when it falls back to 
dummy):

  |     <mbean code="org.jboss.cache.TreeCache"
  |         name="jboss.cache:service=TreeCache">
  |         <depends>jboss:service=Naming</depends>
  |         <depends>jboss:service=TransactionManager</depends>
  |         <attribute 
name="TransactionManagerLookupClass">org.jboss.cache.GenericTransactionManagerLookup</attribute>
  |         <attribute name="NodeLockingScheme">OPTIMISTIC</attribute>
  |         ....
  |         ....
  | 

Here is the log at startup:

  | 

After the implementation of the class 
"pt.iol.services.cache.GlassfishTransactionManagerLookup", here is the 
configuration part:

  |     <mbean code="org.jboss.cache.TreeCache"
  |         name="jboss.cache:service=TreeCache">
  |         <depends>jboss:service=Naming</depends>
  |         <depends>jboss:service=TransactionManager</depends>
  |         <attribute 
name="TransactionManagerLookupClass">pt.iol.services.cache.GlassfishTransactionManagerLookup</attribute>
  |         <attribute name="NodeLockingScheme">OPTIMISTIC</attribute>
  |         ....
  |         ....
  | 

And here is the log (I cut parts of the long exceptions):

What I notice right away is the "stopService(): closing the channel" message 
right after the "TreeCache local address is 192.168.7.1:7800" message. This 
doesn't happen with the dummy transaction manager.

Do I still have to have the following configuration tag:

  |         <depends>jboss:service=TransactionManager</depends>
  | 
Or must this tag be according to the new implementation?

If I take it out, I get the following log:
