Hi, I’m looking for an interpreter for Java that allows me to run my  
Java  
programs on the ruby interpreter. I know there’s a compiler that lets  
you  
run Java programs on the scala interpreter, but I can’t find one to run  
Java on the ruby platform? Any help\>

How about using JRuby to run ruby on Java?

I am yet to give scala ago, however from my current understanding…

scala and java both compile to byte code that runs on the JVM.  
Therefore  
they both share a runtime which will make it more straightforward to get  
the  
two to co-operate.

The only “shared” runtime for java and ruby that I am aware of is,  
JRuby.

Alternatively if your application can be separated into tasks that do  
not  
need a high level of communication you could possibly spawn a java  
process  
seperate from the ruby process.

JRuby can also be used as a glue to assemble Java  
objects. For example, it is possible to parse a  
ruby String containing some xml, using JDOM and  
SAXBuilder. But some special attention must be paid  
to constructing Java arrays from ruby.
