SOAP submission issue

Question

I am using SOAP message over HTTPS.
Our architecture:
Client submission server uses TOMCAT 4.1..29, JDK 1.4.2 with JSSE
I am using com.sun.net. ssl.HttpsURLConnection object to open url connection with submission server.
Submsiion server at the other end has IIS configred to authenticate digital certificate information for the incoming SOAP envelope.
My code works fine except in some instances IIS does not find the certificate info in HTTP session. What causes to strip off this certificate info? If I use browser to submit the same SOAP message it works fine for all submissions, that means IIS server at the other end always receives the certificate info.
I eliminated the doubt on Tomcat web server at my end by simply running the similar code as pure java application using commnad prompt and still I get the same issue ( certificate info is not in session)
Please note that our network has no proxy server. SOAP message file size is just few KB.
Please check the code below and any feedback, suggestion is wel come

Thanks for your reply.
Yes I tried hardcoding the values still the problem persists.
Is there any possible code part i am missing here?
