[maemo-developers] [maemo-developers] JamVM network prob

[From: jiimail at nic.fi]

Hi,
have anyone tried to run any java applications with JamVM that use networking?
I tried to play with http://cybergarage.org/ CyberLink for Java UPnP Development package, but
I couldn't get anything to work in 770. I made a console-based UPnP device that worked fine
in linux and windows, but in 770 it just didnt work. It seemed to work just fine, except that it doesn't
send or receive anything; it doesn't show any exceptions or errors thou.
    I also made a simple program that just sends a multicast packet in IPv6 network and it works in
Linux ( something like: http://www.cdt.luth.se/~peppar/java/multicast_example/ ).  In 770 it gives
following error:
java.net.SocketException
  at java.net.DatagramSocket.getImpl (DatagramSocket.java:214)
  at java.net.DatagramSocket.setReuseAddress (DatagramSocket.java:802)
  at java.net.MulticastSocket.<init> (MulticastSocket.java:110)
  at java.net.MulticastSocket.<init> (MulticastSocket.java79)
  at NetTest.main (NetTest.java:48)
Caused by: java.io.IOException: Socket operation on non-socket
  at gnu.java.net.PlainDatagramSocketImpl.create (Native Method)
  at java.net.DatagramSocket.getImpl (DatagramSocket.java:206)
  ..4 more
I think it crashes in command: MulticastSocket s = new MulticastSocket();

  I use 1.5.0_07 jdk in Linux and Windows and 770 is in IPv6 network and 770 is IPV6 enabled.
If anyone have tried networking application in JamVM, please share your experiences :).
