[tc-users] Fwd: [tc-forge-dev] Can't get the chat JRuby example to work

Hi Andreas,

I think you would be better off using the jruby executable script that 
ships with JRuby rather than crafting your own run.sh.  The LoadError 
you're getting indicates to me that JRuby cannot find its built in 
libraries.  You can pass the Terracotta properties by setting the 
JAVA_OPTS environment variable to include 
the -Xbootclasspath, -Dtc.install-root, and -Dtc.config options.  Also 
make sure to put the tc.jar in your CLASSPATH environment variable, and 
then you can just invoke the jruby script like this:

jruby -I/path/to/terracotta.rb chat.rb Andreas

That said, I've tried this approach and, although I got past the 
LoadError that you get below, I still could not get the example to work 
properly.  I got the following error:

java.lang.Class:-2:in `getDeclaredMethods0': 
java.lang.NoClassDefFoundError: com/tc/object/event/DmiManager
        from java.lang.Class:2427:in `privateGetDeclaredMethods'
        from java.lang.Class:1791:in `getDeclaredMethods'
        from com.tc.aspectwerkz.reflect.impl.java.JavaClassInfo:125:in 
`<init>'
        from com.tc.aspectwerkz.reflect.impl.java.JavaClassInfo:157:in 
`getClassInfo'
        from com.tc.object.bytecode.ManagerImpl:773:in `isRoot'
        from com.tc.object.bytecode.ManagerUtil:440:in `isRoot'
        from com.tc.util.FieldUtils:207:in `isStaticAndNonRootField'
        from com.tc.util.FieldUtils:35:in `get'


I'll keep digging and I'll let you know if I'm able to get this example 
up and running.
