Problem using Runtime.exec

[ktlim]

Hi all, I have some problems regarding the use of Process class.

I have an external application that I need to call using Process. The external application that I use is BulkImageProcessor which is a plugin for Paint.Net. It can use command line parameters to call the functions of the program.

In my code, I wrote something like this.

Runtime rt = Runtime.getRuntime();
String command = "C:\\Paint.NET\\PDNBulkUpdaterCmd.exe ";
command += "\"C:\\pictures\\*.*\" ";
command += "\"\/oC:\\pictures\\converted\" ";
command += "/alg:bicubic ";
command += "/oft:jpg";

Process p = rt.exec(command);

Fatal Error: Could not locate PDNBulkUpdater.dll!
System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0X8007002)
  at System.Reflection.Assembly.nLoadFile(String path, Evidence evidence)
  at System.Reflection.Assembly.LoadFile (String File)
  at PDNBulkUpdaterCmd.Program.Main(String[] args)

I am not sure what went wrong because when I try to execute in the command prompt, the command works. Did I miss out anything?

You need to have PDNBulkUpdater.dll in the working directory of the java programme.
