Re: [JSch-users] NoSuchMethod exception when using JSch in Eclipse 3.4

[Oberhuber, M. <Mar...@wi...>]

Hi Mark,

the method signature from your backtrace indicates a void
return value -- I)V -- but according to the Sources 
that I see, the method in JSch in Eclipse 3.4 has an
int return value. In other words, it appears to be 
source compatible but not binary compatible.

As a workaround, you might want to try using Java
Reflection... 

  Class cSession = mySession.getClass();
  Method mSetPortForwarding = cSession.getMethod(...);
  mSetPortForwarding.invoke...

Cheers,
