[Jython-users] Problems with import of Java Packages

[<wer...@gm...>]

Dear all,

in our company we have special java packages for our inhouse applications.
The following is an extract from an inhouse cookbook to use some of
these packages in Java Programs:

package org.ara.[your name];

import org.ara.araque.preparation.*;
public class FirstExample extends AbstractUserPreparation
{
public void go()
{
sendCommand("[command 1]");
sendCommand("[command 2]");

}
}

I wanted to use these classes in Jython also, therefore I entered various 
import statement
in the jython shell. These are the results
>>> import org.ara.araque
Traceback (innermost last):
 File "<console>", line 1, in ?
ImportError: No module named ara
>>> import org
>>> import org.ara
Traceback (innermost last):
 File "<console>", line 1, in ?
ImportError: No module named ara
>>> import org.ara.araque.preparation.*
Traceback (innermost last):
 (no code object) at line 0
File "<console>", line 1
import org.ara.araque.preparation.*
                                ^SyntaxError: invalid syntax
>>> import org.ara.araque.preparation
Traceback (innermost last):
 File "<console>", line 1, in ?
ImportError: No module named ara
>>> 

... and so on.

I can -however- import other classes normally,e.g. import java or import 
javax.swing
is accepted without problems.

Probably I have to pass some infomation to Jython where to look for these 
packages, but how??
There seem to be hundreds of paths, classpaths ...
Remark: I am a Jython novice ;-)

Maybe it is important that I use Jedit with the Jython Plugin as IDE; the 
Plugin is my interactive Jython shell.
Unfortunately, this makes the situation even more complicated for me. 

Any advice for a desparate beginner?

Thank you

Markus

On a shell for example. Alternatively, you write a bat-file like jython.bat 
(take it as a start), and invoke that.

How do you run other java applications? This is after all a java requirement, 
nothing to do with jython.

You have to include the jars containing your inhouse packages on the 
Java classpath when you invoke Jython.

You will have to figure out how to modify the classpath used by the 
Jedit plugin. Alternately you might want to try running your code from 
the command line with a batch file to set the correct parameters.
