Hello, The first question has little to do with java, but the second question deals with java. From the Windows 2000 command line, is there a way to open up a new command prompt? Typing cmd just opens another instance in the same window, can I open up an entire new command prompt window. Now for the java question. From a java program can I open up a new command prompt? I want to run a client/server program. I want to type: java myApp myApp will start two new command prompts, one for server and one for client. This way I can watch the communication between client/server. I could start the client and server separately, but being a computer scientist I wanted to automate the process.
