[Pydev-code] Debugging Java called from python

[Andrew M. <mi...@nd...>]

I want to stop at breakpoints in the Java code called by my python 
script (via Jython).

However, PyDev's Eclipse debugging interface is handled exclusively by 
the pydevd.py wrapper, and there is no debugger connection to the 
underlying JVM.

I thought to add a launcher argument like 
-agentlib:jdwp=transport=dt_socket,suspend=y,address=localhost:2959, but 
this just results in an error:

  ERROR: transport error 202: connect failed: Connection refused
  ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
  JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports 
initialized [../../../src/share/back/debugInit.c:690]
  FATAL ERROR in native method: JDWP No transports initialized, 
jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

Any ideas about how I can simultaneously debug the script and the Java 
code it calls?

Thanks!
