Weblogic + HTTPS is always a problem, as Weblogic provides its own SSL layer, not implementing Java’s standard SSL interfaces. Usually that casues ClassCastException, however the problem can expose itself different ways.
Because of a need to include proprietary SSL interfaces (WebSphere is another problem platform, from the perspective) – we do not claim, that PD4ML supports HTTPS. It may work with HTTPS, but it is not guaranteed.
I am not sure, the actual problem is SSL-specific. There are some nuances in HTTP session handling and JSP tag instances reusing under Weblogic. If you’d like to debug – we are ready to provide you with PD4ML taglib sources. Please contact support pd4ml com.
