Re: Modules are not found when importing Python in Jython

AFAIK matplotlib contains some C-extension code. This is currently not supported in Jython, JyNI is the way to go here.

However, JyNI cannot load matplotlib as of this writing, but might support it in a future release.

So maybe nothing is wrong with your paths, Jython just does not know what to do with a native library.

Betreff: Re: [Jython-users] Modules are not found when importing Python in Jython

If you're running inside a WAR or EAR, it can be tricky to know what module path to include in your sys.path .. at least, I find it so. (ie: Storing modules in Web-content, and exploded paths by a container, etc)

I tend to have a config file that I pull in as part of bootstrapping, which appends various path to sys.path or the CLASSPATH.

Perhaps try printing our your paths, and making sure the pu modules and .jar dependencies are in there, or adding some paths.

Greetings,

I am trying to use a Python class in my Jython code. The Python code works fine by itself and is using some modules such as matplotlib. However, when I attempt to import it in my Jython code, I get the error:

'No module named matplotlib'.

I, also, have added the path to Python site-packages to my classpath and still did not see the issue resolved.

Thank you
