Thanks, but I have already selected "jython 2.1" as the project type.

There is no "compile" button I that I can see, and "Build" doesn't actually 
compile .py files to classes.

I wouldn't expect PyDev to do that, since only a few of my .py files 
actually need to be compiled with jythonc.

Hi Brad,

Pydev does not actually compile your .py files to classes automatically 
(the interpreter for jython is only specified so that code-completion 
works).

This could be added as a feature request to the pydev tracker... In the 
meantime, I would advise you to create an ant script to compile your 
files. This is not currently done because you could probably go and 
always interpret the .py files with jython at runtime, so, you would 
only (in my view) compile the .py files to classes when you do a 
distribution... altough there are probably some scenarios where it would 
be nice to have it compiled automatically.

Cheers,

Fabio

Yes, I figured I would need to setup some kind of Ant script to compile 
selected .py files to .class files.

Too bad I don't know eclipse well enough to do that. Maybe I need to add 
a builder.. yeah..

So, I am using Junit tests on some java code, which will load .class files 
generated from Jython code and I just want it to work.

regarding code completion w/ Jython. 

Does PyDev only code complete Jython code? When I type in an import 
statement from Java, I can't get it to complete that.

Like

import org.jbpm.ant.  (ctrl space)  I get a beep.

Of course, the same thing happens in Java code too, and I do jave 
jbpm.jar setup in the project.. Well, back to the books I guess.

Hi Brad... a builder would be a good solution if you want to compile all 
your files at any change... I'm not sure if this would be better than 
having an ant script that you would call when you want (it depends on 
what you're looking for to do with it).

As for the code completion, did you add your jar to your 'system 
pythonpath'? -- because of a jython bug it is not enough just adding it 
to the 'project pythonpath'.

Cheers,

Fabio
