Java EE (Java Enterprise Edition) General Discussion

Hello,
I have some stress with my webservice client implementation.

I do the following (I can post source code if needed):
- As usual:
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
- Install my TrustManager
- Install my DefaultHostnameVerifier
- Register a custom type
- Make a javax.xml.rpc.Call to access a webservice

My observations:
The code works well when using an HTTP URL, just changing the target URL to HTTPS causes the problem.
The HTTPS web service (on server) works well seeing a HTTPS client using the weblogic SSL implementation, or an AXIS client can easily connect.
When I use a simple and direct "Open HttpsURLConnection on URL("https://xxx.service?WSDL"); print-out-all-that's-coming-in", it works well. I think my SSL access is made correctly.
The client does not complain about not-installed SSL things, all certificates are accepted, etc. No problem at this part.
System.setProperty("javax.net.debug", "all") is set, but i dont see anything of interrest.
I use the packages contained in 'java_xml_pack-summer-02_01' of SUN (jaxm-1.1_01, jaxp-1.2_01,jaxr-1.0_02 etc and the jsse 1.0.3).
The server is weblogic 7.

Calling
call.setTargetEndpointAddress("http://arakis:7001/traces_ws/searchCertificate");
works well while
call.setTargetEndpointAddress("https://arakis:7002/traces_ws/searchCertificate");
causes (after 2 minutes):

Exception in thread "main"

What I note is that the call is using a HttpURLConnection object and NOT a HttpsURLConnection object (so problems are 'normal' i guess), but I dont have any clue what I have to do to instruct the client to use HTTPS other than specifying HTTPS in the target.

Hope someone has an idea
