Apache Commons Exec can help you to do it.

See http://commons.apache.org/proper/commons-exec/tutorial.html

String line = "your command line";
CommandLine cmdLine = CommandLine.parse(line);
DefaultExecutor executor = new DefaultExecutor();
ExecuteWatchdog watchdog = new ExecuteWatchdog(60000);
executor.setWatchdog(watchdog);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
PumpStreamHandler streamHandler = new PumpStreamHandler(outputStream);
executor.setStreamHandler(streamHandler);
int exitValue = executor.execute(cmdLine);
System.out.println(exitValue);
System.out.println(outputStream.toString());
