Forgive me, I'm new at this...
I am using: Java v 1.4.2_02-b03
: Tomcat v 4.1.29
I�m having trouble getting an HttpsURLConnection to work as expected. I suspect I am
missing something (possibly a great many things) and would appreciate any insight
anyone could provide. I've not been able to find a single source that addresses this
problem although I've found bits and pieces in several places.
I have a simple servlet running in Tomcat that does nothing more than report back that
it is alive. Posting to it at http://myserver:8080/simpleServlet/simpleServlet returns
a response of:
<simpleServletResponse>I am alive!</simpleServletResponse>.
Additionally I have a simple client app that calls the servlet with a POST. The client
can run on either the same machine as the server or a different machine.
1. Using an HttpURLConnection in the client app works fine. I can call the
servlet on either port 8080 (http) or 8443 (https). This works from either machine.
2. If I do nothing other than change the HttpURLConnection to an
HttpsURLConnection then everything falls apart immediately and I don�t understand why
(I do believe I have the proper imports included and it all compiles fine). From
everything I can tell I should be able to replace the one with the other.
3. Keystores & certificates: I have generated certificates for both machines
using keytool and have imported the client machine certificate into the trustedcerts
file on the server machine. I have NOT had any of these certificates signed by a
certificate authority (and due to complexities I won�t go into here that isn�t likely
to happen). Do the certificates need to be signed by a CA in order for
HttpsURLConnection to work?
4. The result of calling the method url.openConnection() is that �null� is
printed to the screen then program execution simply stops. No Exception seems to be
thrown � everything just stops� Why?
HttpsURLConnection conn = (HttpsURLConnection) myurl.openConnection();
Ultimately I would like to get Client-Certification working but haven�t been able to
find a good guide out there for doing so. At the moment I am taking small steps in the
hope of gaining a better understanding. Any help would be greatly appreciated.
Thanks in advance !
