I am trying to get an image through HTTP Connection to my mobile phone. I used emulator from Sun and it is working. When i tried on mobile phone(3650) it will not show anything.
I tried also on Nokia's Developer Suite for J2ME. At the point of connection i have the following exception:

Exception: java/lang/ClassNotFoundException
at com.sun.midp.io.InternalConnector.openPrim(+159)
at com.sun.midp.io.InternalConnector.openPrim(+159)
at com.sun.midp.io.j2me.http.Protocol.connect(+55)
at com.sun.midp.io.j2me.http.Protocol.openInputStream(+64)
at com.sun.midp.io.j2me.http.Protocol.openDataInputStream(+28)
....

Thank you
