Subject Using my own TrustManager for SSL doesn't work in Tomcat
Date Wed, 02 Jul 2003 01:18:28 GMT
Tomcat 4.1.24-LE, Sun JDK 1.4.1_01-b01, Windows XP 

I need to install my own TrustManager to handle client SSL connections. 

If I write a standalone test program to use my own TrustManager (with
HttpURLConnection), it works fine. 

If I install my own TrustManager in a servlet, the result is exactly as if I
hadn't installed my TrustManager at all. 

I've put the code from my source program into a servlet and done some

In the standalone program, the HTTPS connection is implemented by, so setting the default
SSL socket factory with HttpsURLConnection.setDefaultSSLSocketFactory()
works fine.

In the servlet, the HTTPS connection is implemented by, so
setting the default SSL socket factory as above doesn't work. Instead, I
have to use HttpsURLConnectionOldImpl.setDefaultSSLSocketFactory(), which
(unsurprisingly) is deprecated.

Why does Tomcat cause a different implementation of HttpsURLConnection to be
used? How do I get it to use the non-deprecated implementation?

The only vaguely relevant thing I can find is in, which explicitly adds
"" to the "java.protocol.handler.pkgs"
system property. In 1.4, this is not only unnecessary, but will use an old
version of HttpsURLConnection, so this could be construed as a bug. (See
.) However, I'm not using an SSLServerSocket, and I don't have any SSL in my
server.xml, so I'm not sure what affect it has.
