MyFaces can incorrectly determine that Portlets are not supported
-----------------------------------------------------------------
Key: MYFACES-3375
URL: https://issues.apache.org/jira/browse/MYFACES-3375
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314, Portlet_Support
Affects Versions: 2.0.9
Reporter: Paul Nicolucci
There are two issues I'd like to report here.
1) Bridge Class is specific to Apache
org.apache.myfaces.shared.util.ExternalContextUtils.java /
isPortlet(ExternalContext ec) does the following:
return getRequestType(ec).isPortlet();
This class. contains the logic to determine if Portlet is supported by finding
a Bridge class and can return the incorrect value when a Bridge other than the
Apache Bridge is available. For instance in
WebSphere Application Server (WAS) when running in a Portlet environment the
MyFaces code incorrectly returns a Servlet RequestType.
After looking at the code I see why this is:
//Summary of values obtained
javax.portlet.PortletContext = _PORTLET_CONTEXT_CLASS
javax.portlet.ActionRequest = _PORTLET_ACTION_REQUEST_CLASS
javax.portlet.RenderRequest = PORTLET_RENDER_REQUEST_CLASS
javax.portlet.ResourceRequest = _PORTLET_RESOURCE_REQUEST_CLASS
//Find bridge to tell if portal is supported
Class<?> bridge = ClassLoaderUtils.loadClass("javax.portlet.faces.Bridge");
If the above javax.portlet.faces.Bridge Class is not found then
PortletSupported variables are set to false. There needs to be a better way to
determine if a Bridge is
available and therefore determine if Portlets are supported in this environment.
2) Portlet support is determined globally which is not always the case, a more
granular determination is needed at the application level.
