java.io.IOException: unsupported keyword

Hi,

We encountered an error when trying to make a secure connection/https posts to URL "java.io.IOException: unsupported keyword ?". We are using JDK 1.3.1, Weblogic 6.1SP5 in SUN Solaris.

We have imported the following "Comodo Class 3 Security Services CA"/GTE Cuber Trust to the truststore. We were able to do a secure connection to other URL who are using verisign certs.

What could be the problem of the unsupported keyword error? Could this be because of Comodo because we can posts data to a verisign registered URL?

The following are the error message from the logs:

For the sake of anyone who may find this thread via Google as it is one of the top results for this error:

This error is caused by a version of SSL Certificates that Java 1.3 can't cope with. The only known solution is to upgrade Java to 1.4
