Process and Runtime Class

[Siva Masilamani]

Hi

I was just studying about Process and Runtime class and tried few example and got struck with the below problem.

I am trying to call another java program using differnt JDK by apssing argument.

But the problem is when the argument contain spaces i put them inside the " but still it consider them as two arguments.

Please help.

 
            String javaCommand="/java1.5/bin/java OtherClassName";
            String dataString="/"Test Sample/"";
            String unixCommand = javaCommand + " " + dataString;
            System.out.println("Java Command: " + unixCommand);            
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec(unixCommand);
            InputStream input = proc.getInputStream();
            proc.waitFor();
   

After running this code the length of argument is 2 instead of 1.

When i display the passed arguments in another class,it is showing as two arguments namely "Test and Sample" instead of Test Sample.

Did you try to use java.lang.Runtime#exec(java.lang.String[]) instead ?

Yep

That helped me.
Thanks a lot

Make sure to read the article by Michael Daconta called "when Runtime.exec() won't" before using Runtime.exec().
