Bruce Phillips reopened WW-3763:
--------------------------------
This problem has resurfaced in version 2.3.3 and was not fixed in that version.
Please see below:
The 2.3.3 release of the Struts Portlet Plugin breaks using a Struts
application as both a portlet and as a standalone Java application. I believe
the issue is similar to https://issues.apache.org/jira/browse/WW-3763. Thought
we had fixed that issue, but additional changes made to the Struts Portlet
plugin source code after the patch was applied have caused the same problem.
I wonder if this line (69) in PortletRenderUrl
if (PortletActionContext.getPortletContext() == null ||
"none".equalsIgnoreCase(urlComponent.getPortletUrlType())) {
servletRenderer.renderUrl(writer, urlComponent);
return;
}
is part of the issue. Does urlComponent.getPortletUrlType() still return
"none" ?
Here is the stack trace when executing an action that is for the standalone web
application (extends struts-default) when also using the Struts 2.3.3 portlet
plugin and actions in package that extends struts-portlet-default)

> I've got a few Struts application where I use the Struts 2 portlet plugin to
> create a portlet and still have a standalone web application.
> This worked fine through Struts 2 portlet plugin version 2.2.1.1. For an
> example of this problem download and unzip this Eclipse/Maven project:
>
> http://code.google.com/p/struts2-examples/downloads/detail?name=Struts2CRUDPortletExample_Finish.zip
> (read the README.txt file for how to build/deploy).
> This project uses Struts 2.2.1.1. It builds a war file that when deployed to
> Tomcat will register a portlet (that can be used in the Pluto portal
> container) and a web application that can be accessed via calls to Struts
> Actions.
> I tried to upgrade this project to use Struts version 2.3.1.2 (both core and
> portlet plugin). The port let still works fine. But after upgrading to
> 2.3.1.2 when trying to load an action for the standalone version (an action
> defined in package extends="struts-default") I get the following exception:
