      Description

      I'm upgrading a Struts 2 portlet application from 2.2.3.1 to 2.3.1. A test of my Action class that extends StrutsSpringTestCase that passed when using 2.2.3.1 now fails when using version 2.3.1.

      I've created a simple Struts 2 portlet example application to demonstrate the issue. You can download the zipped example here:

      http://www.brucephillips.name/struts/struts2helloworldportlet.zip

      Unzip the download.

      In a terminal window navigate to the project's root folder.

      run mvn clean test

      The test will pass.

      Open the pom.xml and change the struts.version property to 2.3.1 and save your change

      run mvn clean test

      The test will now fail.

      Here is part of the error message in the test report:

      Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.314 sec <<< FAILURE!
      testExecute(com.struts2.tutorial.action.DefaultActionTest) Time elapsed: 1.252 sec <<< ERROR!
      Error creating bean with name 'org.apache.struts2.portlet.result.PortletResult': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.struts2.portlet.result.PortletResult]: Constructor threw exception; nested exception is java.lang.NullPointerException - action - file:/Users/bphillips/eclipse_workspaces/kucard/Struts2HelloWorldPortlet/target/classes/struts.xml:11:74
      at com.opensymphony.xwork2.DefaultActionInvocation.createResult(DefaultActionInvocation.java:224)

      I get the same error if the project is using the Struts Spring plugin or not.

      I think the error is in the Struts unit testing framework as I can still run the project successfully. For example after updating the struts.version in pom.xml enter this command in the terminal window:

      mvn jetty:run

      When you see the message [INFO] Started Jetty Server go to this URL in your web browser: http://localhost:8080/struts2helloworldportlet/pluto/index.jsp and you should see the example portlet.

      Could you register an issue ?

      Looks like the problem is with PortletContext which it is not defined.
      To solve your problem override the method as below in the
      DefaultActionTest class:

          @Override 
          protected ActionProxy getActionProxy(String uri) { 
              ActionProxy actionProxy = super.getActionProxy(uri); 
              ActionContext.getContext().put(StrutsStatics.STRUTS_PORTLET_CONTEXT, 
      new MockPortletContext()); 
              return actionProxy; 
          } 
      

      Thanks in advance
