did you gcj for compiling...
were you able to compile the program

[mangudai_gb]

yeah compilation was successful.....

[mangudai_gb]

compiling was done by
./javac SourceViewer.java
run command: ./java SourceViewer http://www.google.com
result: UnKnownHostError

I don't know java yet (im taking a class this fall) but perhaps this is a DNS reolution error? ive done little programming that accesses network resources, but i always just used ips..... and they were generaly one shot deals or something just for my use. This would be better in the programming and scripting forum.
