R help - Oct 2010 - Calling R function in Java that in turn calls a Java function

I have a function:
call = function()
{
library(rJava)
.jinit(classpath="C:/Documents and Settings/GV/workspace/Test2/bin",
parameters="-Xmx512m")
blah = .jcall("Test2", "D", "sum", 2,2) 
return(blah)
}

In java I do re.eval(call()) and I get a value of null. If I run the call
function directly from R, however, I get 4 as a result. How do I fix this?
