[rjb-users] can't create Java VM

Hi,

It seems fine your environment.
The message 'no such file to load ...' is only RubyGem's debugging
message because $DEBUG set to true, and rjb was successfuly loaded.
Then, another question is: have you ever try to sciprt/server for
testing ? and in the testing environment Rjb can create jvm ?
If so, the problem is caused by Litehttpd's environment.
Does Litehttpd use FastCGI ? If so, you need to set the environment
variables such JAVA_HOME etc, in the FastCGI process, I think, because
the FastCGI process is separated from the parent (Web server's process).

Best regards
