[jruby-user] Re: JRuby on mainframe

Hi Christian,

Thanks for the suggestion. When I execute a ruby file with the complete 
jar file, I get the below error. Apparently the same error was returned 
when another friend executed the jruby shell script in a bash shell 
environment. Let me know if this gives a clue.

$ java -jar jruby-complete-1.7.16.1.jar hello.rb
RubyBasicObject.java:522:in `getMetaClass': 
java.lang.NullPointerException
        from RubyBasicObject.java:634:in `getRuntime'
        from RaiseException.java:139:in `<init>'
        from Ruby.java:3724:in `newNameError'
        from Ruby.java:3712:in `newNameError'
        from Ruby.java:3701:in `newNameError'
        from RubyModule.java:3173:in `defineConstant'
        from EncodingService.java:253:in `defineEncodingConstant'
        from EncodingService.java:246:in `defineEncodingConstants'
        from EncodingService.java:180:in `defineEncodings'
        from Ruby.java:1432:in `initCore'
        from Ruby.java:1295:in `bootstrap'
        from Ruby.java:1220:in `init'
        from Ruby.java:330:in `newInstance'
        from Main.java:258:in `internalRun'
        from Main.java:217:in `run'
        from Main.java:197:in `main'
Thanks,
Murali
