JXTA Application on android

Question

I am trying to build an app that establishes P2P connection between two wifi enabled android device. I have added JXTA 2.5 library into android 2.2, but don't know where i am going wrong. Ending up with run-time exception: No Class found error and Instance not found error.

Is there anything else to be done apart from just including .jar file into android project ? Any configuration to be written ? If yes, please let know how i can write configuration file and employ it in my project ? I am working on final year project, so please let me know if you have any pointers regarding this ?

Thanks in advance !

Here is the Log :

Answer 1

JXTA 2.5 is buggy. Just forget it. I lead release 2.6 and 2.7. We have corrected many issues. I have published a book about it called Practical JXTA II and you can read it online at scribd. It contains examples.

You will probably need a central super peer, unless you only use adhoc connections (broadcasting).
