I've read through the FAQ for Jython and this post Jython and python modules but am not sure how I can determine if a module is written purely in C or Python.
The problem I'm facing is mentioned here http://old.nabble.com/using-NLTK-in-Jython-td28520926.html
Can anyone that has done this shed some light on this? I'm new to Jython.
Thanks,
Did you add C:\Python26\Lib\site-packages\nltk to sys.path as stated in your question? It should really be C:\Python26\Lib\site-packages, which is the directory containing nltk. If you don't want to add the entire site-packages, try moving the nltk folder to another folder.
I was using Eclipse, and including the path to the root dir (nltk or site-packages) did not work. However, making jar files of both the nltk directory and the yaml directory did work. Example,
jar -cf nltk.jar /Library/Frameworks/Python.framework/Versions/7.0/lib/python2.7/site-packages/nltk
jar -cf yaml.jar /Library/Frameworks/Python.framework/Versions/7.0/lib/python2.7/site-packages/yaml
Then in my Jython code I had to add the jar files, which I added to the project's lib dir,
sys.path.append("/Users/peter/phd/lib/yaml.jar")
sys.path.append("/Users/peter/phd/lib/nltk.jar")
In addition to this I had to use the Eclipse import archive file feature to get it to see the NLTK modules.
Had a bit of a struggle with this, so hope it saves someone else some time.
