Question

I am trying to use Runtime.exec to run a class file from my java code but not able to launch the new process on Linux,The same is working on the windows..

I want or launch the process from GUI (which I am running from a jar file named Launch.jar) on a button click.

So I used the following code.

String curpath=System.getProperty("user.dir");
 Runtime.getRuntime().exec(new String[] { "/bin/bash", "-c", "java -classpath"+curpath+File.separator+" Launch.jar LaunchNewProcess" });

Answer 1

I think you need to leave a space after -classpath

Runtime.getRuntime().exec(new String[] { "/bin/bash", "-c",
"java -classpath "+curpath+File.separator+" Launch.jar LaunchNewProcess" });

Update: try this:

Runtime.getRuntime().exec(new String[] { "/bin/bash", "-c",
"java -jar "+curpath+File.separator+"Launch.jar" });
