[antlr-interest] Trying to run AntlrWorks

[Jeffrey Newman]

Hi,
I found a mirror at github.
In this I found what looks like AntlrWorks source.
I downloaded it, ran ant, and it looked like it built.
I found a jar file in a dist dir.
I typed in java antlrworks-1.4.1
I got:
Exception in thread "main" java.lang.NoClassDefFoundError:
antlrworks-1/4/1
Caused by: java.lang.ClassNotFoundException: antlrworks-1.4.1
        at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:319)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:264)
        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:332)
Could not find the main class: antlrworks-1.4.1. Program will exit.

I have not done any java programing on Linux.
I use Qt and C++ most of the time.
My last Java was around 1995 (about years ago). It was very slow, and
very large. But things have changed.

Any help would be appreciated to get me going.

thanks

Jeffrey
