Re: [Jboost-users] running jboost

[Aaron A. <aa...@cs...>]

I run jboost on a Linux x64 machine as well.  When I set the CLASSPATH 
environment variable to nothing, I get the following error:

---------------------------------
You do not have your CLASSPATH variable set correctly.
You have the following dirs in your java path:
You need to have the following in your path:
         JBOOST_HOME/dist/jboost.jar.
         JBOOST_HOME/lib/concurrent.jar.
If jboost.jar doesn't exist, downloaded the distribution again.
To set CLASSPATH, see the documentation in JBOOST_HOME/doc or online.
JBoost jar file is: Exception in thread "main" 
java.lang.NoClassDefFoundError: jboost/controller/Controller
---------------------------------

When I set the CLASSPATH as such:

> CLASSPATH="~/jboost/dist/jboost.jar:~/jboost/lib/concurrent.jar"

where I use tildes '~' instead of '/home/aarvey'  I get the following more 
cryptic error message:

----------------------------
JBoost jar file is: ~/jboost/dist/jboost.jar
Exception in thread "main" java.lang.NoClassDefFoundError: 
jboost/controller/Controller
----------------------------

I'm guessing that using tildes may be your problem.  Try doing full 
classpath yourself and see if that solves your problems.  Let me know 
success/failure.
