Hello, I am having a problem, when i comment this line of code, it
doesn't get the 500 error.

PictureFileScanner pics = new PictureFileFolderScanner(/*
thisfilefolder + */"/images");

But when I have it, I get the ugly error (I copied from the JRUN logs
below)
the definition is this:
public PictureFileFolderScanner(String scanDirectory) throws
IOException

which calls this
   public PictureFileFolderScanner(File scanDirectory) throws
      IOException
   {
      if (scanDirectory.isDirectory()) {
         this.scanDirectory = scanDirectory;
      }
      else {
         throw new IOException("Not a directory \"" + scanDirectory +
"\"");
      }

      filter = new PictureFileFilter();
      rescan(); //upon creation of an image
   }

and here is the rescan() method....

   /**
    * This method scans the directory and appends the list of files
    * to lastPictureNames, depending on what was passed into the
constructor.
    */
   public void rescan()
   {
      aryPictureList = new ArrayList();

      File[] allPictureFiles;
      allPictureFiles = scanDirectory.listFiles(filter);
      for (int i = 0; i < allPictureFiles.length; ++i) {
         try {
            aryPictureList.add(new
PictureFile(allPictureFiles[i].toString()));
         }
         catch (IOException e) {}
      }
      java.util.Collections.sort(aryPictureList);
   }
