using a library (jcurses) that uses jni

I'm having trouble uses the JCurses library. Here's what's happening: 
ls -A
jcurses.jar  .keepme  libjcurses.so  Test.java

javac Test.java -classpath jcurses.jar

ls -A
jcurses.jar  .keepme  libjcurses.so  Test.class  Test.java

java Test -classpath jcurses.jar
Exception in thread "main" java.lang.NoClassDefFoundError: jcurses/system/Toolkit
        at Test.main(Test.java:6)

rm Test.class

jar xvf jcurses.jar jcurses/
...(no jar error outputs)...

ls -A
jcurses/ jcurses.jar  .keepme  libjcurses.so  Test.java

javac Test.java

ls -A
jcurses/ jcurses.jar  .keepme  libjcurses.so  Test.class  Test.java

java Test
Exception in thread "main" java.lang.ExceptionInInitializerError
        at Test.main(Test.java:6)
Caused by: java.lang.NullPointerException
        at jcurses.system.Toolkit.getLibraryPath(Toolkit.java:111)
        at jcurses.system.Toolkit.<clinit>(Toolkit.java:37)
        ... 1 more
Why does running "java Test" the first time output something different than the second just because? Also, why isn't the second working?
