[Pydev-code] Debugging jython called from Java

[dperez <cra...@ya...>]

Hi,

I'm evaluating PyDev and like it.
But I wonder if I can debug Jython code when the jython code is called from
Java code (e.g. a web server).

Thanks in advance for any hint.

Cheers,
David

You should be able to do it with the remote debugger:

Hi,

It works ok.  :-)
I'll try to convince my boss to purchase the extensions.
But the console is working when not using the debug server.  I enter a
simple expression (like 1+1), hit twice Enter and nothing happens.
It works ok when starting standalone .py programs.

Hi,

Another small problem, I remove a breakpoint and continues to be hit.
This happens even if I restart my app and the debug server.

Does the call to pydevd.settrace() takes long? 
I haven't been able to measure how long it takes, because of the breakpoint
I can't remove.
Is it advisable to leave this call in production?

Thanks for any hint.

Hi,

Each time I create a new interpreter, I use this code:

public PythonInterpreter getInterpreter() {
	PythonInterpreter py = new PythonInterpreter();
	py.exec("import pydevd\n"+
		"pydevd.settrace(stdoutToServer=1, stderrToServer=1)");
	return py;
}

It works ok.
The problem is that the PyDev server debugger stops always in the call to
pydevd.settrace().
Can this be avoided?
I only want PyDev to stop when I set a breakpoint.

Have you set: pydevd.settrace(stdoutToServer=True, stderrToServer=True)...
because it should put the message to the console, but if your running
program console is not within the pydev, it will not print to the console
unless you ask it to redirect the output to the pydev output...

Hi,

Thanks Fabio for your explanation.

Now, I have set as you have told me, and it doesn't  still work.
The cause of this is surely that I need to redirect the
org.python.util.PythonInterpreter output to the servlet response stream,
because all the print's in Python code, are sent to the browser.
