Re: [Jython-users] How do I make this easily usable by others? possible bug?

[Moore, G. <Gre...@ad...>]

Hello Again,

I just wanted to let you know I was successful, thanks to all your help
(Charlie and Odi). I was able to put all the java classes I needed under
\org and the *.py under \lib and it all worked wonderfully. I now have a
jumbo all in one jar file that works great! Odi I'd like you permission
to use some of the info on your web page to create a wiki entry that
documents what I did so it might help others.

However, I did notice something odd when I was trying the classpath
method.
This gets a little lengthy sorry about that.

I get different results when typing in commands into the interpreter
then I do when I specify a script on the commandline. This only seems to
happen with the standalone jar I did not see this with the
non-standalone installation. Let me explain a little further:

On Windows XP sp2 with the following Environment:

PATH=3D"c:\Program Files\Java\jre1.5.0_11\bin"
CLASSPATH=3Dc:\dist\lib\commons-codec-1.3.jar;c:\dist\lib\commons-logging=
-
1.0.4.jar;c:\dist\lib\commons-httpclient-3.1-rc1.jar;c:\dist\lib\dom4j-1
=2E6.1.jar;c:\dist\lib\jaxen-1.1.1.jar;c:\dist\lib\log4j-.2.8.jar;"c:\Pro=
g
ram Files\Java\jre1.5.0_11\lib\rt.jar"

This is what I saw:
C:\jython2.2>java -cp %classpath%;.\jythonStandalone.jar
org.python.util.jython

Jython 2.2rc2 on java1.5.0_11
Type "copyright", "credits" or "license" for more information.
>>> from javax import swing
Traceback (innermost last):
  File "<console>", line 1, in ?
ImportError: cannot import name swing
>>> from javax import *
Traceback (innermost last):
  File "<console>", line 1, in ?
ImportError: no module named javax
>>> ^Z

However everything works fine if I use, for example, the Jython Console
from http://code.google.com/p/jythonconsole/ using a similar command to
the one above: C:\jython2.2>java -cp %classpath%;.\jythonStandalone.jar
org.python.util.jython c:\Libs\jythonconsole-0.0.4\console.py=20

At the top of console.py there are a bunch of swing imports.
Just for the purposes of completeness, If I type in a line like "from
java import *" or "from java.lang import String" everything works fine
and there are no import errors.

Here are some other tests I ran if your interested

C:\jython2.2>java -cp %classpath%;.\jythonStandalone.jar
org.python.util.jython
Jython 2.2rc2 on java1.5.0_11
Type "copyright", "credits" or "license" for more information.
>>> from org.dom4j import *
Traceback (innermost last):
  File "<console>", line 1, in ?
ImportError: no module named dom4j
>>> from org.apache.commons.httpclient import *
Traceback (innermost last):
  File "<console>", line 1, in ?
ImportError: no module named apache
>>> from org.apache.commons import *
Traceback (innermost last):
  File "<console>", line 1, in ?
ImportError: no module named apache
>>> import org
>>> dir
<built-in function dir>
>>> dir(org)
['__name__', 'python']
>>> ^Z

Now Using the SAME environment settings but the NON standalone jar every
thing seems to work just fine. As shown below.

C:\jython2.2>java -cp %classpath%;.\jython.jar org.python.util.jython
*sys-package-mgr*: processing new jar,
'C:\dist\lib\commons-codec-1.3.jar'

>>> from javax import *
>>>

Sorry this got a little longwinded. But I don't know a more concise way
of documenting it.

So I guess the question is... Bug or feature? I couldn't test this with
2.1 because this appears to be specific to the standalone jar and it was
unavailable with the 2.1 release.

Regards,
Greg.
