Classpath from Web Start

Question

Hello!
I need make following funcionality : from GUI application, opne new JFrame in another JVM.
I do it like ->
                String mainClass = MainClass.class.getName();
                String classPath = System.getProperty("java.class.path");
System.out.println(" classpath -> " + classPath ); // when run it from Web Start in output see :   claspath -> C:\Program Files\Java\jre6\lib\deploy.jar
                ProcessBuilder pb = new ProcessBuilder( "java", "-classpath", classPath, mainClass );
                try {
                    taProcess = pb.start();
                } catch (IOException e) {
                    e.printStackTrace();
                }When I run it from my IDE - everything working fine. I can run something in other JVM.
But if I run it from Java Web Start, I get wrong classPath (web starts classPath)
Question is : How can I get my application class path, when I run it from Web start?? ( press on jnlp link)

Answer 1

You code make use of manifest of the jar file to reload the classpath.
