[Link Grammar] Using relex.jar?

[yO2gO]

Hello,

I have compiled and exported relex classes with all the data files and
required libraries in a jar file using Eclipse.
When I try to use this relex.jar I get the following error


Error: Unable to initialize JWNL:java.io.FileNotFoundException: .\data
\wordnet\file_properties.xml (The system cannot find the path
specified)
Warning: Unable to initialize WordNet Java API (JWNL).
Was -Dwordnet.configfile set correctly?
Does the wordnet.configfile contain the right paths?
Will use command-line interface; this will negatively impact
performance.
Exception in thread "main" java.io.FileNotFoundException: .\data\relex-
tagging-algs.txt (The system cannot find the path specified)

I have checked the paths. These files exist. I cannot figure out what
classes are looking for these files. I was thinking of hard-coding the
file names so that it will work at least.

Can someone help me with this?
Does anyone have a relex.jar that works? It would be very helpful

Thanks

Try using 'ant' instead.

The build.xml file that is included with relex will place the required
algs files into the jar, where they can be found. my guess is that
your eclipse build system is failing to place this, and the other various
data files, into the jar.

I don't use eclipse, so I don't know ... am I supposed to ship
some sort of project file that eclipse users can use, so that
this kind of problem doesn't occur?

I did a build with "ant" as well. But that does not generate a jar
file.
Can you help me with this?

And for Eclipse, you don't need to ship anything. A project can be
built just from the sources.

Thanks

Try "ant help", which will list the build options.

Well, apparently that's not true, as otherwise you wouldn't
have written your first email :-/

I keep getting this error. I have checked for all the paths.

What is going wrong? I have used 'ant' in this case

That's the cause of your problem:

 java.io.FileNotFoundException: C:\yPrograms\WordNet\dict\verb.idx (The system cannot find the file specified)

Edit the file  ./data/wordnet/file_properties.xml and fix the WordNet path.

The WordNet path is correct. But the verb.idx file does not exist in the WordNet distribution. I use Windows. I tried WordNet 2.1 and also the WordNet 3.0. Neither have the verb.idx file. There only a verb.exc file in that directory.

Where can I find the verb.idx file?

[Murilo Saraiva de Queiroz]

Sorry, I don't have a Windows machine with WordNet installed so I can't answer that properly. I did a quick search and find someone recommending using WordNet 2.0 in Windows when using JWNL (the library we use to access WordNet from Java), but I don't know if it will works. 

[Yogesh]

The WordNet that you have, does it have the verb.idx file (in the dict directory). If yes, it would be great if you could just ship it to me. At least the FileNotFoundException will be resolved.

Thanks

The verb.idx error is a red herring; you don't want the
PrincetonRandomAccessDictionary anyway.

You want the FIleBackedDictionary, and that one is failing for
you with the following:

[java] Error: Unable to initialize JWNL:
net.didion.jwnl.JWNLException: Una
ble to install net.didion.jwnl.dictionary.FileBackedDictionary
[java] net.didion.jwnl.JWNLException: The properties file must

ctionary path

So I think you need to review your properties.
