.bat files and java program

I know that I have posted something just like this before, but I just can't get this to work. I want to have my application call a .bat file and execute it. Can anyone please supply me some code (maybe just a small program) that executes a .bat file from within the program itself. This would be very helpful. I just can't get it to work at all.

To open notepad in a windows system:
import java.io.*; // Needed for IOException
public class Notepad
public static void main(String[] args)
try
Runtime.getRuntime().exec("notepad");
catch (IOException ioExc)
System.out.println("Something has gone horribly wrong!");
Notes:
1) notepad is usually in the path system variable. You will probably have to type in the entire path to the .bat file you want to execute.
2) The .exec(programName) will block until the program is terminated.
3) You are losing any semblance of system independance by doing this.

Executing a .bat file from java code

Im writing a utility and i need to be able to create and execute a .bat file from my program. I can create the .bat file fine but when i try to execute it nothing happens. I tried to use the following line of code to try to execute the .bat file (called make.bat) :
try
String parameterString = "\"C:\\WINNT\\System32\\cmd.exe\" C:\\ITS_Test\\make.bat";
Runtime.getRuntime().exec(parameterString);
catch (Exception e)
System.out.println(e);
The Runtime.getRuntime()exec() method worked fine when trying to execute an excel file but for some reason it dosen't want to work for the DOS prompt. Any ideas?

Thanks everyone for all the replies.
I have tried all the above with no luck. Im using netbeans, does anyone think that it could be a problem with the IDE.
I tired the following code :
String parameterString = "cmd.exe /C \"C:\\ITS_Test\\make.bat\"";
Process pr = Runtime.getRuntime().exec(parameterString);
pr.waitFor();
This code does not throw any exceptions but just hangs. I also tried:
String [] parameterString = {"cmd", "/c", "C:\\ITS_Test\\make.bat"};
Process pr = Runtime.getRuntime().exec(parameterString);
pr.waitFor();
and:
String parameterString = "\"C:\\WINNT\\System32\\cmd.exe\" \"C:\\ITS_Test\\make.bat\"";
Process pr = Runtime.getRuntime().exec(parameterString);
pr.waitFor();
with the same result. Does anyone know why it just hangs and nothing happens (no exceptions thrown)?

How to Call .XDO file From Java Program

Hi,
I have developed a report in using BI Publisher version 10.1.3.
I created the report and it only created XDO files. If I want to call XDO file from Java program how I can do that.
What are the APIs available to do that.
Thanks
-Ashutosh

Hi,
the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

Everytime I try to type something in the search box a further box appears to tell me this is a JSON file and what program should I use to open it.
This has only happened since reinstalling my system a couple of weeks ago.
I am not really interested in what a json file is I simply want to get rid of this pop up box.

Photoshop does not close files and the program does not quit.

I have been on the phone with tech support for over an hour. Photoshop does not close files and the program does not quit. I am on a Mac and I am using Photoshop CC 2014.

Have you tried uninstalling Photoshop CC and re-installing? Another thing to try is to remove all Photoshop CC plist files. There is also the Cleaner tool:
