Everything looks okay here, so I am not sure what is going wrong. Can you 
try if you can run other java programs, perhaps even setting

\usemodule[filter]
\traceexternalfilters
\defineexternalfilter[JAVA][filtercommand=java]

\starttext
\startJAVA
This is a test
\stopJAVA
\stoptext

and check the console output to see if you see messages that java is 
running (you should see the standard message about how to use java). If 
java is being called correctly, then the error is on the java end of 
things and I don't know how to debug that.
