Subject SSL with IBM SDK and IBM JSSE
Date Thu, 13 Feb 2003 17:43:18 GMT

I am using Tomcat 4.1.18 with IBM SDK 1.4.0.  When I have the SSL connector
enabled in server.xml, I can't start Tomcat.  I get the following error:

     java.lang.NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provider

In the server.xml I am using the following for the SSL connector:

     <!-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->
    <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
               port="8443" minProcessors="5" maxProcessors="75"
             acceptCount="100" debug="0" scheme="https" secure="true"
               useURIValidationHack="false" disableUploadTimeout="true">
               clientAuth="false" protocol="TLS"

I have replaced the actual keystore password with xxxxxxxx above.  Since
the IBM SDK 1.4.0 uses the IBM JSSE the following is in my

I have found that the SSL connector works fine when using the IBM SDK 1.3.1
with the Sun JSSE 1.0.3.  In this case my file contains:

Does anyone know if there is a way to configure Tomcat to use the IBM SDK
with the IBM JSSE for the SSL connector.  I have also tried this with
Tomcat 4.0.4 with the same results.  I looked at the source for Tomcat
4.0.6 and found the following in that makes me
think that Tomcat can only work with the Sun JSSE:

     * The name of our protocol handler package for the "https:" protocol.
    private static final String PROTOCOL_HANDLER =

     * The name of the system property containing a "|" delimited list of
     * protocol handler packages.
    private static final String PROTOCOL_PACKAGES =

     * The configured socket factory.
    private sslProxy = null;

I really would like to find a way to use the IBM JSSE if possible.  Any
help would be greatly appreciated.
