I'm working on creating a very simple app to stop and start a windows service. I need it to have a GUI interface so I choose JAVA. If you know a simpler language let me know. As a sample I would like for it to stop and start print spooler. I've created the GUI interface using NetBeans, but I need help with the coding part. Please help. Thanks!

Thanks everyone!
This is my code:
private void StopSpooler() {
String[] args = {"stop"};
String[] command = {"cmd.exe", "/c", "sc", args[0], "spooler"};
try {
Process process = new ProcessBuilder(command).start();
InputStream inputStream = process.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String line;
while ((line = bufferedReader.readLine()) != null) {
System.out.println(line);
}
} catch(Exception ex) {
System.out.println("Exception : "+ex);
}
}
private void StartSpooler() {
String[] args = {"start"};
String[] command = {"cmd.exe", "/c", "sc", args[0], "spooler"};
try {
Process process = new ProcessBuilder(command).start();
InputStream inputStream = process.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String line;
while ((line = bufferedReader.readLine()) != null) {
System.out.println(line);
}
} catch(Exception ex) {
System.out.println("Exception : "+ex);
}
}
And I created a batch file I run as admin an calls the jar app
@echo off
java.exe -jar C:\test\MyServiceTool.jar
pause
In Windows Command Line: You need Administrator rights to do so. To stop a windows service:
net stop Spooler
To start a windows service:
net start Spooler
In Java you can execute a dos command with:
try {
Runtime.getRuntime().exec("net stop spooler");
} catch (IOException ex) {
JOptionPane.showMessageDialog(null, ex.getMessage());
}
