Executing two commands at the same time from Runtime.getRuntime

Question

Hi everybody,
I m executing a command of imageMagic from javacode to crop and for changing the quality of image.The code is as below :
String changeQuality = new String("convert " + originalImage
                    + " -crop " + imageWidth + "x" + imageHeight + "+" + imageX
                    + "+" + imageY + " -quality " + quality + " " + finalImage);
               Runtime.getRuntime().exec(changeQuality);
But before going to next page of jsp I want the size of the finalImage. So I m calling a new function from the base file, from which i m calling the above function, for getting the size of image:
public String getSize(String finalImage) {
               proc = Runtime.getRuntime().exec("identify " + finalImage);
As identify cmd gives the size and various values of image but this command is showing the size zero. and if try to read the file then it shows FileNotFoundException.It means the file is not on the server.
What should i do to execute both the command and getting the right result.
Any help is appreciated.
Thanks in advance.
