After discussing with BrianC, we took a different approach - instead of trying to make things serializable or to switch the weblogic behavior off, we wrap objects with dummy handler that holds wrapped object in a transient field. This is done on setAttribute() and on getAttribute() the original object is unwrapped.

As suggested by BrianC, there are two central places where all requests go through: MainServlet#protectRequest and #encryptRequest. While this is true for Tomcat; I find out we need to fix some more places on Weblogic (?!).

Note: this fix only solves HttpServletRequest.getAttribute(). Similar thing should be applied on session and servletContext once when we notice this issue.

The problem happens in the following line of microblogs-portlet\microblogs\view_microblogs_entries.jsp:

We put PortletURLImpl in the request as attribute and Weblogic serialize it on getAttribute(). For more details about this Weblogic behavior, please visit: http://www.liferay.com/community/wiki/-/wiki/Main/Weblogic+tips#section-Weblogic+tips-*.getAttribute%28%29+and+Serialization

I've tried to fix using following ideas:

• enable optimistic-serialization property, both in weblogic.xml (was already set) and on domain

• running Weblogic in PRODUCTION mode, since in the development mode the server may test attributes regardless the above setting

• finally, I've tried to add missing Serialized interfaces where it was missing:

  • SharedSessionServletRequest

  • PortalContextImpl

  • PortletContextImpl

  • PortletRequestImpl

but this still didn't help. After above changes, weblogic.servlet.internal.WebAppServletContext is not serializable and we can not do anything about it (not Portals class).

Running into this issue again so I am reopening this ticket:
