HELP!!! JRUN JSP 500 Error

[rel...@gmail.com]

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);
}
