Trouble calling a secure Web Service requiring client certificate

[frank.bowar]

I've got a TOMCAT application that pulls data from a Web Service and just
recently the Web Service was hardened to require client certificates.
 
I debugged all my certificate issues and got my Java class that talks to the
Web Service working just fine as a stand-alone app.  However, I'm having
trouble getting it to work within Tomcat.  My certificate is not being sent
to the Web Service.
 
This is how I initialize my keystore and truststore:
 
    System.setProperty("javax.net.ssl.trustStore",
"c:\\certs\\datahub.keystore");
    System.setProperty("javax.net.ssl.trustStorePassword","turstpass");
    System.setProperty("javax.net.ssl.keyStore",
"c:\\certs\\SDXWebservice.pfx");
    System.setProperty("javax.net.ssl.keyStorePassword","keypass");
    System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");

 
I'm using Tomcat 6 and JRE 1.6.
 
My web app is not secure and I had been using the out-of-the-box server.xml
file, but I've been playing with an SSL connector on 8443, but I still can't
get it to work and am not sure if I need to add this connector or not.
 
I'm not a security expert at all and have really been struggling with this
for far too long!  
 
Any and all help is appreciated.
 
Thanks in advance.
