Help client API creating association Instance

[Stefano Campanini]

I'd like to use WBEM Services to build a prototipe for  tha MAIS research project. (I'm using 0.95)
I try to use client API to crete instances but I cannot create Instaces of association class, I think I haven't understand something.
This is a part of my code:
...
CIMInstance transientInstance1 = protEndPointClass.newInstance();
        transientInstance1.setProperty("Name",new CIMValue("135.175.20.22"));
        transientInstance1.setProperty("NameFormat", new CIMValue("Ipv4"));
...
CIMObjectPath savedOp1 = tep.client.createInstance(transientInstance1.getObjectPath(), transientInstance1);
...   
So for the second Object(ProtocolEndPoint):
...
transientInstance2.setProperty("Name",new CIMValue("135.175.20.21"));
        transientInstance2.setProperty("NameFormat", new CIMValue("Ipv4"));
...
CIMObjectPath savedOp2 = tep.client.createInstance(transientInstance2.getObjectPath(), transientInstance2);
    
Now I try to create an instance of association class (ActiveConnection)
...
CIMInstance acInstance = acClass.newInstance();
CIMValue cmv1 = new CIMValue(savedOp2,acInstance.getProperty("Antecedent").getType());
acInstance.setProperty("Antecedent",cmv1);
CIMValue cmv2 = new CIMValue(savedOp1,acInstance.getProperty("Dependent").getType());
acInstance.setProperty("Dependent", cmv2);
acInstance.setProperty("TrafficType", new CIMValue("2"));

// The follow throw an Exception
CIMObjectPath savedOp4 = tep.client.createInstance(acInstance.getObjectPath(), acInstance);
    
At the step above I got a problem, An exception is thrown but I can udestand Why!!!
The StackTrace of this is the follow (it is too long):
