How to get Custom Property from a Portlet?

I have a JSR 286 portlet deployed into Portal. I would like to set a custom property in this portlet and get it either from my controller or JSP view so that I can customize the look based on the value of this custom property.

What methods are availabe? and what suggestions you have to achieve this goal?

Thank you!

Hello,

This is not currently possible.

The properties added through PortletResponse are exposed as headers in HttpServletResponse. Methods for retireving headers in HttpServletResponse were introduced in Servlet Specification version 3.0. Portal 8.2 targets Servlet Specification 2.4 for compatiblity with supported servlet containers, none of which support the latest Servlet 3.0. Portal will target Servlet 3.0 in future releases when support is added for containers that implement it (Tomcat 7, WebLogic 12, WebSphere 8, ...) .

Here is the the API to set and retrieve properties.

    Set property from PortletResponse:

        void setProperty(String key, String value)
        void addProperty(String key, String value)

    Retrieve property from HttpServletResponse (assuming Servlet 3.0):

        String getHeader(String name)
        Collection<String> getHeaderNames()
        Collection<String> getHeaders(String name)

I tested by deploying Portal to Tomcat 7 (not supported for 8.2) then updating web-app to target Servlet 3.0. This appears to work, but please note that modifying the deployment descriptor in this way is unsupported and not gauranteed to work.
