[platform-debug-dev] Re: Where do -agentlib:jdwp args come from?

[Andrew Mickish <mickish@xxxxxxx>]

I tried inserting the JVM argument, and got this in my console:

  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)

My Eclipse-generated command line was like:

   "C:\Program Files\Java\jdk1.6.0_02\bin\javaw.exe"
       -agentlib:jdwp=transport=dt_socket,suspend=y,address=localhost:8000
       -classpath "C:/jython2.2.1/jython.jar;...;C:\Program 
Files\Java\jdk1.6.0_02\jre\lib\ext\tools.jar"
       
"-Dpython.path=C:\Workspace\myPy\src;C:\jython2.2.1\Lib;...;C:\Program 
Files\Java\jdk1.6.0_02\jre\lib\ext\tools.jar"
       -Dpython.security.respectJavaAccessibility=false 
org.python.util.jython pydevd.py
       --vm_type jython --client localhost --port 1221 --file 
C:\Workspace\myPy\src\example.py
