Attunity Tuxedo Adapter

Question

Hi,
we are using Tuxedo BDTA (Bi-directional Tuxedo Adapter) for some time to connect our BPEL processes with Tuxedo.
Now we want to do the same thing with EJB 3.0. And hier is the source code:
Context context;
ConnectionFactory connectionFactory;
Connection connection;
Interaction interaction;
System.out.println("Getting initial context");
context = new InitialContext();
System.out.println("lookup eis/legacy/TUX_MTA");
connectionFactory = (ConnectionFactory) context.lookup("eis/legacy/TUX_MTA");
System.out.println("Getting attu connection");
connection = connectionFactory.getConnection();
System.out.println("Getting interaction");
interaction = connection.createInteraction();
String routing = "1";
String target = "ADS_IF20";
String payload = "<xml><author>el2_sm</author>";
System.out.println("Creating attunity spec");
AttuInteractionSpec spec = new AttuInteractionSpec("SMBK_MTA", InteractionSpec.SYNC_SEND_RECEIVE, 60);
System.out.println("Getting record factory");
RecordFactory recordFactory = connectionFactory.getRecordFactory();
System.out.println("Create mapped record");
MappedRecord input = recordFactory.createMappedRecord(target);
input.put(ROUTING_INST, "1");
input.put(ROUTING_DIS, target);
input.put(FI_DATUM, payload);
System.out.println("Calling service " + target);
Object output = interaction.execute(spec, input);
System.out.println("Terminating interaction");
interaction.close();
System.out.println("Closing connection");
connection.close();
evrything works until executing the interaction, which ended with the following exception:
Internal Server Error (Caught exception while handling request: oracle.oc4j.rmi.OracleRemoteException: java.lang.ClassCastException: com.attunity.adapter.core.CoreMappedRecord; nested exception is:
     java.lang.ClassCastException: com.attunity.adapter.core.CoreMappedRecord)
Can somebody tell me, what is the problem here. I tried with AttuConnection and other Attu classes but it did not help.
The documentation "Oracle® Application Server Adapters for Tuxedo User's Guide" for 10.1.3.4 does not contain any usable or complete example.
thanks in advance,
Sasa
