I would like to run a class file from my application. I managed to compile the java file, but got stack with executing it. To be more clear, i will post my code here:
    public static void main(String args[]) throws Exception
        try {
            String line;
            Runtime rt = Runtime.getRuntime();
            String[] cmd = { 
                "c:/progra~1/Java/jdk1.5.0_05/bin/javac.exe", "c:/Temp/Test1/MainTest.java"};    
            Process p = rt.exec(cmd);
            int exitVal = p.waitFor();
            System.out.println("After compilation value: " + exitVal);
            String[] cmd2 = {
                "cmd.exe", "/c","c:/progra~1/Java/jdk1.5.0_05/bin/java.exe -cp MainTest"};
            Runtime rt2 = Runtime.getRuntime();
            p = rt2.exec(cmd2);
            BufferedReader input = new BufferedReader(new InputStreamReader(p.getErrorStream()));
            String temp = "";
            while((temp = input.readLine()) != null) {
         catch(IOException e) {
            System.err.println("Error on exec() method");
After compilation the exit value is 0 and creates a class file. But when i try to run it is either jumps to an exception and prints errors or prints the error from a BufferedReader:
java.lang.NoClassDefFoundError: c:/Tem/Test1/MainTest
Exception in thread "main"

I have tried several way for cmd2 commands but just would not run.
Any help would be much appriciated.
