a.final int MAX_STUDENTS;

Dear Ranchers

Can anyone help me with this problem:

I have created a servlet using javamail api. When I test the servlet I get a null pointer exception thrown by the InternetAddress class. See the source code comment //******. The mail is sent and received succesfully by the recipient although a null pointer is thrown. The stack trace states the problem occurs at line 569 of InternetAddress.java. I dont have the source code.

I have disguised the problem behind a friendly error page that refreshes and redirects back to the home page.

Source code as follows:
package tsl.mail; import javax.servlet.*; import javax.servlet.http.*; import java.io.*; import javax.mail.*; import javax.mail.internet.*; import java.util.*; public class MailServlet extends HttpServlet{ .... public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException{ // retrieve form parameter values String to = request.getParameter("to"); String from = request.getParameter("from"); String subject = request.getParameter("subject"); String message = request.getParameter("message"); // Create a session with the mail server Properties props = new Properties(); props.put("mail.host","gwmail.nmit.vic.edu.au"); Session mailSession = Session.getInstance(props,null); try{ // Create address objects - null pointer is thrown next line Address fromUser = new InternetAddress(from); // ******* Address toUser = new InternetAddress(to); // Create the message body Message body = new MimeMessage(mailSession); body.setFrom(fromUser); body.setRecipient(Message.RecipientType.TO, toUser); body.setSubject(subject); body.setContent(message,"text/plain"); Transport.send(body); }catch(AddressException ae){ throw new ServletException(ae.getMessage()); }catch(MessagingException me){ throw new ServletException(me.getMessage()); }catch(NullPointerException npe){ throw new ServletException(npe.getMessage()); } } // doGet } // MailServlet

Any OCP ranchers
Can anyone advise on the following?
Do I need to enroll in Oracle training course (very expensive) to learn and obtain certification? Is DIY acceptable and will it be ok with Oracle themselves?

Dear Ranchers
I come accross www.cheatsheet.net. where they are offering real exam questions for $29. I didnt find SCWCD only SCJP1.4. Could it be true? If so does this site devaluate the certification.
Has anyone purchased their mocks/real questions? I would be interested in your feedback.
