java linux processbuilder
hey guys im currently trying to make a litlle handy tool, u see i am a network administrator and my boss told me that he wanted me to monitor the network and block certain sites and ip for some game servers, so for the monitoring part we are going to redirect all traffic on the network to a server where we can monitor the traffic before sending it to the gateway… for this we are going to use arpspoof in linux and i have finished a solution for the blocking of sites and servers, and what i am g

java process runtime.exec processbuilder
I have a Java class that is using Runtime.exec() to execute a cscript process with one String of several arguments that is retrieved from a database. One of these arguments includes newline characters that need to be preserved, but Runtime.exec() removes the newline characters. The problem doesn’t exist when using ProcessBuilder, but I’d rather not have to worry about parsing my list of arguments. Is there a way to preserve the newlines when calling exec()?In case anyone wants to see it, her

java stdout processbuilder
Is it possible to redirect the output stream back into a process, or not redirect it at all?The backstory: I am trying to launch an executable using processbuilder. (Source dedicated server / srcds.exe to be exact)As a result of launching it with the processbuilder, the console window of this executable remains empty. A few seconds after launch, the executable crashes with the error “CTextConsoleWin32::GetLine: !GetNumberOfConsoleInputEvents” because its console is empty.

android android-service processbuilder intentservice
I’m aware of this SO question: Java ProcessBuilder: Resultant Process Hangs and this problem should not be similar, because my long and CPU-intensive task continues happily after its launching activity/service has crashed.Initially I tried wrapping the operation into new Thread(new Runnable() {…}); and the result was the activity crashing with Process my.package.name (Pid: 1000) has died.Then I moved the task into a Service’s onStartCommand and also into a IntentService’s onHandleIntent both r

java linux crash multithreading processbuilder
I’ve been trying to use Java’s ProcessBuilder to launch an application in Linux that should run “long-term”. The way this program runs is to launch a command (in this case, I am launching a media playback application), allow it to run, and check to ensure that it hasn’t crashed. For instance, check to see if the PID is still active, and then relaunch the process, if it has died.The problem I’m getting right now is that the PID remains alive in the system, but the GUI for the application hangs.

I have been experimenting with Process and ProcessBuilder and come with this SSCCE.import java.io.IOException;public class TestProcess {public static void main(String[] args) {Process process = null;ProcessBuilder pb = new ProcessBuilder(“notepad.exe”);try {process = pb.start();} catch (IOException e) {e.printStackTrace();}//have some time to close notepadtry {Thread.sleep(10*1000);} catch (InterruptedException ignored) {}try {System.out.println(process.exitValue());} catch (IllegalThreadStateEx

java processbuilder
I am having a strange issue when trying to execute a block of code (more particularly the ProcessBuilder class in Java)Code that works:package modules.user.verify;import java.io.*; import java.util.*; import java.net.*;public class VerifyUser { public static void main(String[] args) {boolean listening = true;try {ServerSocket server = new ServerSocket(20002);while(listening) {Socket client = server.accept();PrintWriter out = new PrintWriter(client.getOutputStream(), true);BufferedReader in = new

java shell exec processbuilder
I’m looking into a most efficient way to decide:Should I preprend the user-provided command line with the shell executable If yes, what would that executable be? (/bin/sh? /usr/bin/perl? /usr/bin/ksh? c:/../cmd.exe?)It is known that to start a shell script from Java one should start the shell instead:ProcessBuilder pb = new ProcessBuilder(“/bin/sh”, “script.sh”, “arg1”, “arg2);To start a binary one should start the binary itself:ProcessBuilder pb = new ProcessBuilder(“/path/binary”, “arg1”, “arg

java 7zip processbuilder
I am writing a java program on windows platform. I need to compress certain files into a zip archive. I am using ProcessBuilder to start a new 7zip process:ProcessBuilder processBuilder = new ProcessBuilder(“7Z”,”a”,zipPath,filePath); Process p = processBuilder.start(); p.waitFor();The problem is that the 7zip process never exits after completion. It does create the required zip file but after that just hangs in there. This means that the waitFor() call never returns and my program gets stuck. P

I am experiencing a weird problem with the Java ProcessBuilder. The code is shown below (in a slightly simplified form)public class Whatever implements Runnable {public void run(){//someIdentifier is a randomly generated stringString in = someIdentifier + “input.txt”;String out = someIdentifier + “output.txt”;ProcessBuilder builder = new ProcessBuilder(“./whateveer.sh”, in, out);try {Process process = builder.start();process.waitFor();} catch (IOException e) {log.error(“Could not launch process.
