Use of Opennlp
Hello, I am new to this tools. I downloaded 1.5 version, and added the 3 jar
files into my windows 7 environment variable:
C:\Program Files\Apache Software Foundation\Tomcat
7.0\webapps\nlpTools\WEB-INF\classes\nlpTools\openNLP\lib\jwnl-1.3.3.jar;
C:\Program Files\Apache Software Foundation\Tomcat
7.0\webapps\nlpTools\WEB-INF\classes\nlpTools\openNLP\lib\maxent-3.0.0.jar;
C:\Program Files\Apache Software Foundation\Tomcat
7.0\webapps\nlpTools\WEB-INF\classes\nlpTools\openNLP\lib\opennlp-tools-1.5.0.jar
Then I wrote a helloWorld.java to test it, but it says the package can't be
found:
import opennlp.tools.chunker.ChunkSample;
public class Test{
public static void main(String[] args) {
System.out.println(" NLP tools ... ");
}
c:\>javac Test.java
Test.java:1: package opennlp.tools.chunker does not exist
import opennlp.tools.chunker.ChunkSample;
^
1 error
Where was I wrong? Thanks.

hi, Jorn:
I am setting up a Web demo for the tool. If it takes nearly one minute to
load all the models from SentenceDetection to Parsing. Is there a way to
make it faster?
sometimes, it is running out of memory.
Thanks

The JVM searches the classpath for required classes, in your case
the opennlp jars are not on the classpath and thats why the runtime
cannot find the SentenceModel class.
Just add at least the maxent and opennlp-tools jars to your classpath
and it will stop complaining about missing opennlp classes.

Yes, try to use the "-classpath" argument of javac,
so you need to write something like this:
javac -classpath opennlp-tools-1.5.0.jar Test.java

Fwd: Use of Opennlp

Thanks. But I added it to my classpath:
C:\myclasses\opennlp-tools-1.5.0.jar, and then run "javac Test.java", it
shows that error: cant find the packages.
Any idea? thanks.

Hello,
please post questions about the usage on the opennlp-users mailing list.
The opennlp-tools-1.5.0.jar must be on the classpath of the compiler.
Try something like this:
javac -classpath opennlp-tools-1.5.0.jar Test.java
Then it will be able to find the referenced ChunkSample class.
Hope that helps,

Re: Use of Opennlp
Posted by Jörn Kottmann <ko...@gmail.com>.
Hello,
please post questions about the usage on the opennlp-users mailing list.
The opennlp-tools-1.5.0.jar must be on the classpath of the compiler.
Try something like this:
javac -classpath opennlp-tools-1.5.0.jar Test.java
Then it will be able to find the referenced ChunkSample class.
Hope that helps,
Jörn
