Hi,
I try to use the transactionmanagement from client like the manual says :
         
  InitialContext ctx = new InitialContext();
  |   tx = (UserTransaction) ctx.lookup("UserTransaction");
  |   tx.begin();
  |   ... 
That works realy fine. But when I am connected to an user defined provider

      java.util.Hashtable env = new java.util.Hashtable();
  |       env.put( Context.PROVIDER_URL, "myserver:1199");
  |       InitialContext ctx = new InitialContext(env);
  |        tx = (UserTransaction) ctx.lookup("UserTransaction");

it fails (at lookup) with following exception:

  | javax.naming.CommunicationException: Failed to connect to server 
mydefaultserver:1099 [Root exception is 
javax.naming.ServiceUnavailableException: Failed to connect to server 
172.30.1.22:1099 [Root exception is java.net.ConnectException: Connection timed 
out: connect]]
  | 
  |     at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:213)
  | 
  |     at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1187)
  | ...
  | 

Is there any solution for this problem ?

I think the problem is in  
org.jboss.tm.usertx.client.ClientUserTransactionObjectFactory:
   static private UserTransaction getUserTransaction()
  |    {
  |       if (userTransaction == null) {
  |          // See if we have a local TM
  |          try {
  |             new InitialContext().lookup("java:/TransactionManager");
  | 
  |             // We execute in the server.
  |             userTransaction = ServerVMClientUserTransaction.getSingleton();
  |          } catch (NamingException ex) {
  |             // We execute in a stand-alone client.
  |             userTransaction = ClientUserTransaction.getSingleton();
  |          }
  |       }
  |       return userTransaction;
  |    }

because a new InitialContext will be created.

TIA
  Dirk
