Hello all,
I've a problem with Jython and importing .py inside a jar.
I'm putting .class and .py files inside .jar files.
myjar.jar
MyJar\SomeClass.class
MyJar\main.py
MyJar\otherModule.py
So I add the myjar.jar to Jython's sys.path
org.python.core.PySystemState pySys = new
org.python.core.PySystemState();
pySys.path.insert(0,new PyString("/path/to/myjar.jar"));
and execute main.py
//We pass the PythonInterpreter the modified
PySystemState
PythonInterpreter i = new PythonInterpreter(null,
pySys);
//Find the entry in the jar for the python file and
execute it.
//It should be able to find any resource inside the jar.
JarFile jFile = new JarFile("/path/to/myjar.jar");
ZipEntry zipEntry = jFile.getEntry("MyJar/main.py");
InputStream pythonInputStream =
jFile.getInputStream(zipEntry);
i.execfile(pythonInputStream);
main.py will execute fine, it'll be able to do
from MyJar import SomeClass
with no problem
However, If I try to import the other .py in the same jar, it won't
find it:
from otherModule import *
or
from MyJar.otherModule import *
I always get this:
ImportError: no module named otherModule
at org.python.core.Py.ImportError(Unknown Source)
at org.python.core.imp.import_first(Unknown Source)
at org.python.core.imp.import_name(Unknown Source)

at org.python.core.PyCode.call(Unknown Source)
at org.python.core.Py.runCode(Unknown Source)
at org.python.util.PythonInterpreter.execfile(Unknown Source)
I've tried adding more paths to sys.path, with no luck:
pySys.path.insert(0,new PyString("/path/to/myjar.jar/MyJar"));
pySys.path.insert(0,new PyString("file:jar:/path/to/myjar.jar!"));
and nothing works, any ideas would help. I know this has to work,
because I previously had a problem where I couldn't do
import os
and then I added the "Lib/" folder inside jython.jar and now I'm able
to import all those standard jython modules, so, somehow, jython is
able to import .py within a .jar, help would be very much appreciated.
