Execute java class from a batch file called from runtime.exec

Question

Hi.
I don´t know if this question fits here.
I wan´t to execute a batch file (on Win XP) with runtime.exec. That batch file will execute another java program.
I have the following code:
Resolutor.java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
public class Resolutor {
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          Runtime r = Runtime.getRuntime();
          //String[] command = { "cmd.exe", "/C",".\\lanzar.bat .\\ .\\ 001.res:001.dtt" };
          String[] command = { "cmd.exe", "/C",".\\tarea\\lanzar.bat " + args[0] + " " + args[1] + " " + args[2]};
          try {
               //Process proceso = Runtime.getRuntime().exec("lanzar.bat");
               Process proceso = Runtime.getRuntime().exec(command);
               InputStream stderr = proceso.getErrorStream();
            InputStreamReader isr = new InputStreamReader(stderr);
            BufferedReader br = new BufferedReader(isr);
            String line = null;
            System.out.println("<ERROR>");
            while ( (line = br.readLine()) != null)
                System.out.println(line);
            System.out.println("</ERROR>");
               int exitVal = proceso.waitFor();
               System.out.println("EXITVAL: " + exitVal);
          } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (InterruptedException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
}lanzar.bat
java Lanzador %1 %2 %3Lanzador.java
import java.util.Vector;
public class Lanzador {
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          Repetitiva rpt=new Repetitiva();
          String rutaFicheros=args[0];
          String rutaResultado=args[1];
          String[] ficheros=args[2].split(":");
          Vector<String> ficheroDatos=new Vector<String>();
          for(int i=0;i<ficheros.length;i++){
               ficheroDatos.add(ficheros);
               System.out.println(ficheros[i]);
          System.out.println("RUTA DE FICHEROS: " + rutaFicheros);
          System.out.println("RUTA DE RESULTADOS: " + rutaResultado);
          System.out.println("CALCULAR");
          rpt.setRepetitiva(ficheroDatos, rutaFicheros, rutaResultado);
          rpt.calcular();
}I´ve got Resolutor.class in /res and the other two files (and the rest of the files for running) in /res/tarea.
If I execute /res/tarea/lanzar.bat from the command line everything works fine, it calls java and runs lanzador without problem.
The problem comes when I try to execute the batch file via Resolutor.class. It executes the batch file without problem, but it throws a *java.lang.NoClassDefFoundError: Lanzador* when launching the new java application.
Any ideas of how can I solve that problem. (It must do it via batch file).

Answer 1

Well, I tried putting in the bat file java -classpath .\tarea Lanzador %1 %2 %3 and didn´t work.
I ve tried the bat modification, and the directory in x.txt is k:\res instead of k:\res\tarea.
I´ve tried to modifiy it to java .\tarea\Lanzador and didn´t work so I have put a cd like the following and it appears to work.
cd tarea
java Lanzador %1 %2 %3Thanks for the replies.
