IMAP/SSL: problem connecting from a web application

Question

Hi,
I try to connect to a IMAP/SSL server (with a self-signed certificate) from a web application. I followed http://www.javaworld.com/javatips/jw-javatip115.html.
When I try to connect from a java application it works fine. But when I try it from a servlet, it fails:
javax.mail.MessagingException: gaeron.gcrm.test.mail.DummySSLSocketFactory;
  nested exception is:
     java.net.SocketException: gaeron.gcrm.test.mail.DummySSLSocketFactory
     at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:461)
     at javax.mail.Service.connect(Service.java:236)I use Tomcat 5.5, jdk1.5.0_06 and javamail-1_3_3_01. Here is my code:
          Security.setProperty( "ssl.SocketFactory.provider", "gaeron.gcrm.test.mail.DummySSLSocketFactory");
Properties props = new Properties();
Session session = Session.getDefaultInstance(props);
Store store = session.getStore("imaps");
store.connect(server, 993, username, password);
store.close();Can anybody help me?
Thanks,
Előd.

I am not sure there is a class called MBoxSSLFactory. Is that a typo? We are in the same boat. We have a web application running on Tomcat that needs to connect to the IMAP store on the MS Exchange 2003 Server. It was working fine until we enabled Basic Authentication - SSL/TLS required setting on it.
In order to eliminate any complications due to Tomcat and all we are trying to get a simple standalone program that talks to IMAP server (using the DummySSLSocketFactory, DummyTrustManager etc) working.
I am stuck on the same error: (shown below is the stack trace and the code we are running). I have tried all the suggestions that have been posted on this "Unconnected Sockets not implemented" issue. I have tried it with both Jdk 1.4.2_08 and JDK 1.5.0.
The JavaMail version is 1.4. If I use JavaMail version 1.3.1 it complains that there is no store type "imaps". If I use "imap" and not "imaps" as the store type I end up getting "Authentication Failed" exception.
Instead of a DummyTrustManager I even tried importing a certificate. We have deployed a Verisign trial certificate on the EXchange server side. So when we run the InstallCert program (http://blogs.sun.com/andreas/entry/no_more_unable_to_find) it allows us to add the valid certificates to our keystore. Once that is done we have tried to create TrustManager based on that keystore. But NOPE..No success. same problem.
We have been stuck on this one for the last 4 days and we have a very critical client deployment that is hampered by this one. I know it is turkey time now..but would really appreciate it if some one can help us out.
