Description

I am running Struts "7.0.0-M9" along with Spring Boot "3.3.2" + Spring Security with embedded tomcat version is "10.1.26"

 

Environment:

Struts 2 "7.0.0-M9"

Spring Boot "3.3.2"

Tomcat "10.1.26"

Java 21

 

I have a Struts Action class annotated with :

@Result( 
  name = Action.INPUT,
  location = "/WEB-INF/content/%{#request.device}/login.jsp",
  type = "dispatcher"
)

 I have noticed that after returning from the Action class (ViewLoginAction.java) the framework is invoking the above JSP using a DispatcherType.GET instead of DisplatcherType.FORWARD.

StrutsRequestWrapper is missing request attribute "jakarta.servlet.forward.request_uri"

Then, tomcat "org.apache.catalina.core.ApplicationDispatcher" doForward method fails to find that attribute in the following line:

if (hrequest.getAttribute(FORWARD_REQUEST_URI) == null)
{ 
  ...
  ...
  // then tomcat defaults to setting value of various request attributes 
  ...
  ...
}
 

 

And after that, tomcat calls "processRequest(request, response, state);" in the same instance "ApplicationDispatcher" and fails to resolve a FORWARD dispatcher type below.

 

Instead, it resolves a REQUEST. And when tomcat sees REQUEST dispatcher type it does a GET on the JSP, instead of FORWARD.

 

Should StrutsRequestWrapper have request attribute "jakarta.servlet.forward.request_uri"?  If not why tomcat is resolving a GET instead of FORWARD? 

 

I do not see this issue with Struts 6.6.0 + Spring 2.7.18 with embedded Tomcat "9.0.83". which is based on javax.servlet instead.
