Command line won't work with ProcessBuilder

Question

Hi,
I am trying to run the following command line from the ProcessBuilder:
java -cp .\dist\ReflexionTest.jar ReflexionTest.Main2but I always get a
CreateProcess error=2, the specified file cannot be foundYet, when I run the code from a DOS window, it works fine. I have made sure that both commands are started from the same directory.
Anybody knows what is happening? How can I solve this?
Thanks,
J.

Answer 1

I am using the second constructor.
Here is the code for class Main1:
package ReflexionTest;
import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
public class Main1 {
    public static void main(String[] args) {
        System.out.println("Starting Main1");
        System.out.println("Main1 USER DIR = " + System.getProperty("user.dir"));
        ProcessBuilder MyPB = new ProcessBuilder("java -cp " + "ReflexionTest.jar" + " " + Main2.class.getName());
         File TempDir = new File(System.getProperty("user.dir") + File.separator);
         MyPB.directory(TempDir);
        Process TheProcess = null;
        try {
            System.out.println("Starting Main2 process\n");
            TheProcess = MyPB.start();
            System.out.println("\nExit value = " + TheProcess.exitValue() + "\n");
        } catch (IOException ex) {
            System.err.println(ex.toString());
}And here it is for class Main2:
package ReflexionTest;
public class Main2 {
    public static void main(String[] args) {
        System.out.println("Main2 started !!!");
}Both classes are in the same Netbeans project. Main1 tries to call Main2 from the ReflexionTest.jar itself. I have manually copied the ReflexionTest.jar file in the user dir file.
Thanks,
