Executing a Java Program from Windows Application using c#

[Rohan Cambel]

I am developing a Windows Application in C# for compiling and executing any java program.

I have used System.Diagnostics. Well, the problem is that, compile works properly (it creates a .class file which I then execute using command prompt and it works!) but when I try to run the program from the Windows application itself, it does not display the output.

Here is the code for Run:

ProcessStartInfo processStartInfo = new ProcessStartInfo("C:\\Program Files\\Java\\jdk1.6.0_30\\bin\\java.exe");
processStartInfo.WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
processStartInfo.Arguments = "HelloWorld";
processStartInfo.UseShellExecute = false;
processStartInfo.ErrorDialog = false;
processStartInfo.RedirectStandardError = true;
processStartInfo.RedirectStandardInput = true;
processStartInfo.RedirectStandardOutput = true;

Process process = new Process();
process.StartInfo = processStartInfo;
bool processStarted = process.Start();
process.WaitForExit();

StreamWriter inputWriter = process.StandardInput;
StreamReader outputReader = process.StandardOutput;
StreamReader errorReader = process.StandardError;

String error_string = errorReader.ReadToEnd();
textPad.AppendText(error_string+"");
textPad.AppendText("OUTPUT:\n\n");
String output_string = outputReader.ReadToEnd();
textPad.AppendText(output_string);


Well, I kind of displayed the output in a richtextbox (i.e, textPad) but how can I display the output in the Command Prompt itself?

The cmd window is shown momentarily and then it disappears.

Please help. Your valuable comments will be acknowledged. Thank you.
