package com.WCM.Vignette; import java.io.*; public class Import_In_VCM { /** * @param args * @throws WCM_Exceptions * @throws * */ void Call_From_Import() throws WCM_Exceptions { File dir1 = new File("C:\\Path"); String s = null; try { //start the command prompt String[] cmds = {"cmd.exe /k start dir"}; int i; for(i=0;i<cmds.length;i++) { System.out.println(cmds[i]); } /* * run the vgnimport command */ Process p1 = Runtime.getRuntime().exec("cmd.exe /k start vgnimport -u user -p pwd -h machine:port -s D:\\Datanew12.zip",null,dir1); // read the standard output of the command BufferedReader stdInput = new BufferedReader(new InputStreamReader(p1.getInputStream())); //BufferedReader stdError = new BufferedReader(new // InputStreamReader(p1.getErrorStream())); // read the output from the command System.out.println("Here is the standard output of the command:\n"); /*while ((s = stdInput.readLine()) != null) { System.out.println(s); } // read any errors from the attempted command System.out.println("Here is the standard error of the command (if any):\n"); while ((s = stdError.readLine()) != null) { System.out.println(s); } catch (IOException e) { System.out.println("hi u r in catch"); throw new WCM_Exceptions("Exception occurred "); } } }

In this code when i commented while(s = stdInput.readLine()) the prog started working
But now the problem is two command prompts are strated simultaneously for the same file.
I mean i am calling this class( Call_From_Import) from other class in a loop in which values in zip file are modified...If i use system.exit or p1.waitfor or p1.destroy only 1 cmd prompt is started
