Thanks for the help and I can get the error message from the browser. Now the problem
is that I can't get the .clp result to the browser by writing
" toClient.println(nd.stdout());"
or
" toClient.println(nd.stderr());"
It prints out "java.io.PrintStream", but not the content I wanted
Shall I re-route the PrintStream in NullDisplay?
