Re: [Pydev-code] Debugging Java called from python

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

The Pydev remote debugger does not help me stop at breakpoints in Java 
code.  It still only stops at breakpoints in Python code.  Am I missing 
something?

I can stop at Java breakpoints when I run my python script from Eclipse 
directly with Jython (i.e., without the pydevd.py wrapper).  In this 
scenario, my Eclipse launcher produces a command line like this:

C:\Program Files\Java\jdk1.6.0_02\bin\javaw.exe
    -agentlib:jdwp=transport=dt_socket,suspend=y,address=localhost:4088
    -Dfile.encoding=Cp1252
    -classpath C:\jython2.2.1\jython.jar org.python.util.jython 
src\example.py

However, when I run my python script from Eclipse using PyDev, there is 
no -agentlib:jdwp in the command line:

C:\Program Files\Java\jdk1.6.0_02\bin\javaw.exe
    -classpath "C:\jython2.2.1\jython.jar;...;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 3088 --file src\example.py

I believe the -agentlib:jdwp is the link between the launched process 
and the Eclipse debugger.

I think all that I need is for the Java process spawned by PyDev to use 
the -agentlib:jdwp argument.

Any idea how we could enable that in PyDev?  Seems like an enhancement 
that would benefit Jython users generally.
