Hi All, <div>My Issue get resolved.</div><div><br></div><div>I missed to add commons-codec-1.3.jar in my class path which was resulting org.apache.commons.codec.DecoderException in </div><div>XmlRpcClientWorker.execute(final XmlRpcRequest pRequest,final AsyncCallback pCallback).</div>
<div><br></div><div>As this code is using reflection to create a object (dont know why) but it results corrupted node (NodeType) object in NodeClient(URI uri, Class<NodeType> interfaceClass). (line 59).</div><div><br>
</div><div>I just printed Node object in constructor NodeClient() and Its printing stacktrace of DecoderException. As I havent done much of Reflection, dont know the reason.</div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>

Sorry Damon, My Mistake<div>NodeConfiguration has member xmlRpcPort which is 0 by default.</div><div>Its not set any where and is used to creare tcpRosBindAddress and passed to SlaveServer as a parameter.(See internal node constructor)</div>

</div>Ok.<br>

<br>
</div>Can you see the messages using rostopic echo? What about if you use<br>
roscore instead of the RosCore class in rosjava?<br>
<div><br>

<br>
</div>Correct.<br>
<div><br>
> is xmlRpcPort is used in this communication?<br>
<br>
</div>Which argument is it exactly you're asking about? I don't see it<br>
specified in your code snippet.<br>
<br>
In general, a port argument of 0 means that the OS should pick an<br>
available port to bind to.<br>
