Running external class

Question

Hi
i need call some external class from web service method.
Normally it works, but somehow it doesnt work when i'm calling it from web service.
Do you know where is problem and how to solve it?
Thanks in advance.
code is bellow:
try {
            String[] cmd = new String[3];
            cmd[0] = "cmd.exe" ;
            cmd[1] = "/C" ;
            cmd[2] = "java -cp lib\\jade.jar;lib\\jadeTools.jar;lib\\iiop.jar;lib\\base64.jar;lib\\http.jar;lib\\log4j-1.2.14.jar;. resender.WatchdogStarter bubak bubu";
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec(cmd);
            // any error message?
            StreamGobbler errorGobbler = new
                    StreamGobbler(proc.getErrorStream(), "ERROR");
            // any output?
            StreamGobbler outputGobbler = new
                    StreamGobbler(proc.getInputStream(), "OUTPUT");
            // kick them off
            errorGobbler.start();
            outputGobbler.start();
            // any error???
            int exitVal = proc.waitFor();
            System.out.println("ExitValue: " + exitVal);
        } catch (Throwable t) {
            t.printStackTrace();
        }where StreamGobbler is:
public class StreamGobbler extends Thread {
    InputStream is;
    String type;
    StreamGobbler(InputStream is, String type) {
        this.is = is;
        this.type = type;
    public void run() {
        try {
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String line=null;
            while ( (line = br.readLine()) != null)
                System.out.println(type + ">" + line);
        } catch (IOException ioe) {
            ioe.printStackTrace();
}

Answer 1

solved.
Problem was that application server couldnt find external class so i
specified it with absolute path.
