am simply trying to detect which files in current dir (i.e., current
webapp) are directories..

You can get a list from File by using a FileFilter
<http://java.sun.com/javase/6/docs/api/java/io/FileFilter.html>

<snippet>
package snippet;
public class Snippet
{
  public static void main( String [] args )
  {
   File test = new File( args [0] );
   if ( test.isDirectory() )
   {
     File [] subDirs = test.listFiles(
       new FileFilter ()
       {
         public boolean accept( File t )
         {
          return t.isDirectory();
         }
       } );
     for ( File t : subDirs )
     {
       System.out.println( t.getName() );
     }
   }
  }
}
