get the output of c++ application from java application

[manel1989]

hi everyone!

I want to get the output of my c++ application from my jaca applacations o i use a file abs.bat to get it done
i used this code in .bat:

start readxmlresou.exe 

that commande line opens readxmlresou.exe that is in my desktop and execute it, now i want to get the output of that application to my application java, i wrote this code but i doesn't work:

public Process DoSysCommand(boolean bWait) throws IOException
       {

           Runtime runtime1 = Runtime.getRuntime();
           final Process process = runtime1.getRuntime().exec(new String[]{"C:\\Users\\abdelhalim\\Desktop\\abs.bat", "readxmlresou.exe"}, null, new File("C:\\Users\\abdelhalim\\Desktop\\"));
           process.getInputStream();
           OutputStream out = null;
           InputStream in= null;

        // Consommation de la sortie standard de l'application externe dans un Thread separe
        new Thread() {
            public void run() {
                try {
                    BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
                    String line = "";
                    try {
                        while((line = reader.readLine()) != null) {
                            // Traitement du flux de sortie de l'application si besoin est
                           System.out.println("line="+ line);           
                        }
                    } finally {
                        reader.close();
                    }
                } catch(IOException ioe) {
                    ioe.printStackTrace();
                }
            }
        }.start();

        // Consommation de la sortie d'erreur de l'application externe dans un Thread separe
        new Thread() {
            public void run() {
                try {
                    BufferedReader reader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
                    String line = "";
                    try {
                        while((line = reader.readLine()) != null) {
                            // Traitement du flux d'erreur de l'application si besoin est
                        }
                    } finally {
                        reader.close();
                    }
                } catch(IOException ioe) {
                    ioe.printStackTrace();
                }
            }
        }.start();

           try
           {
               process.getInputStream();
               if(bWait)
               {
                   process.waitFor();


               }
           }

           catch(InterruptedException e)
           {
               System.err.println(e.getMessage());
           }
           return process;
       }
}

what i get when i press the button in the GUI in java is the readxmlresou.exe ( the console vs2010 c + + shows the output of the c++ application) and then it bloked there , the 2 applications bloked in this stage,even c + + application does not close

I will try to figure it out , so if YOU have any idea about that ,I am really very grateful for your help
