No, it works. You can execute java.exe from within java.exe.
I just tried it with the following program:
import java.io.*;
public class TestProcess {
public static void main(String[] args) throws IOException {
String s = null;
String[] cmdArray = null;
if(args.length < 1) {
System.out.println(
"You must give atleast one argument as the command to execute");
System.exit(0);
} else if(args.length > 0) {
cmdArray = args;
}
Runtime rt = Runtime.getRuntime();
Process p = rt.exec(cmdArray);
BufferedReader br = new BufferedReader(
new InputStreamReader(
p.getInputStream()));
if(br != null) {
while( (s = br.readLine()) != null) {
System.out.println(s);
}
}
}
}
And to test it, give arguments on the command line, like:
java TestProcess java HelloWorld
It worked for me, so you can definitely invoke java.exe from within java.exe
