At the beginning of my trivial servlet below, I get a NoSuchAlgorithmException when I try to create a KeyGenerator. I'm just trying to use the standard Sun cryptography libraries which are part of the JDK 1.6 release (which is running om my server: 1.6.0_03). The libraries should be in the jre1.6.0_05\lib\ext\sunjce_provider.jar For some reason, even if I include the jar in my classes directory, it still gives the exception. Maybe some other class was already loaded by Resin before it got to my stuff?? It works fine on my local Tomcat installation.

Any suggestions would be appreciated.

import java.security.NoSuchAlgorithmException;
import javax.crypto.KeyGenerator;

public class HelloWorldServlet extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();


        try {
            KeyGenerator kg = KeyGenerator.getInstance("AES");
            out.println("<p>Created Keygen!!!</p>");
        } catch (NoSuchAlgorithmException e) {
            out.println("<p>Create Keygen Failed!!!</p>");
        }
