 Operational Systems & Java

 Is anyone aware of any way to determine OS type, version...

Answer: There is in the java.lang.System

try first:

Properties p = System.getProperties();

System.out.println(p);

to see what properties you can get(CPU among others)..

you then can:

 String prop = System.getProperty("aproperty(the CPU among other)");

Java application.

Answer:  There is!

execute a shell and then write the name of the shell script on the shells stdin stream.

Process child = rtime.exec("/bin/bash");

BufferedWriter outWriter = new BufferedWriter(new

OutputStreamWriter(child.getOutputStream()));

outWriter.writeLine("filename");

outWriter.flush();

Is there any way to manage Systray Icons with Java? I didn t even find anything in

call the program from Java with JNI.
