[Jython-users] Trouble using Stanford parser with Jython

[Jinseung Eu <jin...@li...>]

Hello!

I am having a trouble using a program called Stanford Parser 1.6.1 (To
unzip it, you may have to unzip it twice):
(http://www-nlp.stanford.edu/downloads/lex-parser.shtml#Download).

I have posted several messages but have not received a full solution. So
I am posting it again with all updates.

I renamed the unzipped folder as "stanford-parser-2008" and put it
inside the jython 2.2.1 folder and added the path as follows:

>> import sys
>> sys.path.append("stanford-parser-2008\\src")
>>

Then I accessed the following packages within src, and this worked:
>> import edu.stanford.nlp.parser
>>

But when I try to access a class within it I get an error:

>> import edu.stanford.nlp.parser.Parser
Traceback ...
File "<console>"....
ImportError: no module named Parser

>> from edu.stanford.nlp.parser import Parser
Traceback ...
File "<console>"....
ImportError: cannot import name Parser

This problem was encountered by someone else two years ago
(http://www.nabble.com/Importing-non-builtin-java-modules-to8957425.html#a8999193)

Here Charlie resolves the issue by adding "stanford-parser.jar" to sys.path.
--> But this doesn't work for me. I don't know why. Do I need to put the
unzipped folder somewhere else?

Below, Jeff suggests I need to compile the "Parser.java" file to
"Parser.class" file.
--> I tried the compilation but failed (Perhaps I put the file in the
wrong place for compilation, or the file is not meant to be compiled).
--> Also I am not entirely convinced that a .class file is necessary
here. Jython can import .java files like System.java (in java.lang) and
Random.java (in java.util). Then, why do I have to have a .class file
for the Stanford parser? /

Can someone please help me get solve this puzzle?
Thanks a lot.
