RE: [Jython-users] import from jar--clarification

[Phil S. <psu...@es...>]

I've been wrestling with the same problem, just posted to 
jython-dev about it in fact.

As far as I can tell, what you want to do is not supported but
you can add support with the following patch to
org/jython/core/imp.java in jython-2.1a3:
imp.java
498a499,502
>         //if it's not a builtin or in the python path, try the classpath
>         ret = loadFromClassLoader(name, imp.class.getClassLoader());
>         if (ret != null) return ret;
>

Then you need to add the standard modules to the jython.jar file.
I have an ant file that does this if you're interested.

Let me clarify:

Im not asking how to put classes in the classpath. I'm asking how to put all
of the standard python library (the .py modules like re.py and httplib.py)
that compile to *$py.class into a jar in such a way that when a
PythonInterpreter runs over the line: import re, it can import the python
library from a jar.


Thanks.

$ java -help
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)

where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    -classic      to select the "classic" VM
                  If present, the option to select the VM must be first.
                  The default VM is -client.

    -cp -classpath <directories and zip/jar files separated by :>
                  set search path for application classes and resources
    -D<name>=<value>
                  set a system property
    -verbose[:class|gc|jni]

The use -classpath option to the JVM you run jython with.
