I am working on a simple method that will assign a specific extension

find anything marking a valid extension, however, I do not want to add
an extension if one is found.

You might try the URI class. Make a URI, get the path, and then just
check that one string for a valid extension. This will be much easier
than trying to parse a URI yourself.

package uritest;

import java.net.URI;
import java.net.URISyntaxException;

public class Main {

     /**
      * @param args the command line arguments
      */
     public static void main(String[] args) throws URISyntaxException {
         // TODO code application logic here

         URI uri = new URI( "http://www.blah.com/registration/" );
         String path = uri.getPath();
         if( path.endsWith("/") )
             path = path.substring( 0, path.length()-1 );
         if( !path.matches( ".+\\..*") )
             path += ".jsp";
         System.out.println( path );
     }

}
