Java + Ubuntu Commands

[midnightray]

My first non uni and app. Basically installed php, mysql and apache from the repo's and wanted a gui to stop/start apache/mysql like XAMPP.

Ok after googling and playing around with netbeans. I have found this method of running commands through Java.



private String SHELL = "gnome-terminal";
private String SHELL_PARAM ="-e";

//Method to execute commands
public void doAction(String command,String servicename, String actionname){
ProcessBuilder launcher = new ProcessBuilder();
Map<String, String> environment = launcher.environment();
launcher.redirectErrorStream(true);
launcher.command(SHELL,SHELL_PARAM,command);

Process p;
String lines;
try {
p = launcher.start();
p.waitFor();
BufferedReader is = new BufferedReader(
new InputStreamReader(p.getInputStream()));

BufferedReader err = new BufferedReader(
new InputStreamReader(p.getErrorStream()));

String errMsg = "";
while ((lines = is.readLine()) != null) {
errMsg += lines + "\n";
}

while ((lines = err.readLine()) != null) {
errMsg += lines + "\n";
}
setStatusText(errMsg);
setStatusText(servicename + " " + actionname + "...");
} catch (Exception ex) {
ex.printStackTrace();
}
}

//method called from action listeners placed by netbeans like e.g.
// doAction("sudo /etc/init.d/apache2 stop", "apache", "stopped");
// last 2 params are for a message to be put in a text area,
// setting text area is a method, not included but a simple .setText()




The only really things I would like is, is there a way to get the full screen password box like when accessing admin stuff.

Can Java be themed to match Ubuntu's default human theme, it looks horrible really.

Maybe using gksudo...

That works great, starting to think Java isn't so bad for writing little apps in.

But how can I make it look pretty like Gnome ? :)

edit: after googling

try{
UIManager.setLookAndFeel(
"com.sun.java.swing.plaf.gtk.GTKLookAndFeel");
}catch(Exception e{
}

works great!

Java does support changing the Theme from Swing to a more native theme.

I don't like how Swing looks by default, the only benefit it has is that it will be consistent on all platforms. I usually use a native look and feel.

Here is a Sun article about setting look and feel. http://java.sun.com/docs/books/tutorial/uiswing/lookandfeel/plaf.html


As for the sudo thing. Either rn the program with gksudo java program or maybe run a system command like this:

gksudo cat /dev/core that will force a gksudo popup. I think generally this is considered a bad thing though, programs aren't usually supposed to elevate themselves.
