include - Struts2 ActionContext and Response for chaining actions -

i have pretty complex problem struts2 chaining actions, in advance patience reading problem. try best describe clearly.

below struts.xml:

<?xml version="1.0" encoding="utf-8" ?> <!doctype struts public     "-//apache software foundation//dtd struts configuration 2.0//en"     "http://struts.apache.org/dtds/struts-2.0.dtd">  <struts>     <constant name="struts.enable.dynamicmethodinvocation" value="false" />     <constant name="struts.enable.slashesinactionnames" value="true" />     <constant name="struts.devmode" value="false" />       <package name="default" extends="struts-default" namespace="/">         <action name="test" class="com.bv.test.testaction1" >             <result name="success" type="chain">y</result>         </action>          <action name="x">             <result name="success">/index.jsp</result>         </action>          <action name="y" class="com.bv.test.testaction2">             <result name="success">/index.jsp</result>         </action>     </package> </struts> 

my logic this: when accessing /myapp/test, testaction1 handle request; in testaction1, "include" action x (my 2nd action in config) this:

responseimpl myresponse = new responseimpl(response); requestdispatcher rd = request.getrequestdispatcher("/x.action"); rd.include(request, myresponse);  

and important thing using customized responseiml when including "x.action".

after including, return "success", result chains action y (3rd action in config);
, @ last, testaction2 continue handle request, go success result, , jsp should rendered, what see blank page.

the jsp file simple: index.jsp

<h1>test!</h1> 

my question/puzzle is:

1. in testaction1, if response servletactioncontext, getting different ones before , after including; before including default response, after including got instance of customized responseimpl; expect same one: i.e.: default response;
2. in testaction2, response servletactioncontext, got instance of customized responseiml. important thing, think should default response instance here, i.e.: org.apache.catalina.connector.response, running on jboss;
3. i getting different actioncontext in testaction2 (compared actioncontext in testaction1).

this problem drive me on nuts, have spent days on it.
advice appreciated!
million!!

my code:

testaction1:

public class testaction1 {   public string execute() {     actioncontext ac = actioncontext.getcontext();     system.out.println("before including: action context : " + ac);     httpservletrequest request = servletactioncontext.getrequest();     httpservletresponse response = servletactioncontext.getresponse();     system.out.println("before including: response : " + response);      responseimpl myresponse = new responseimpl(response);     requestdispatcher rd = request.getrequestdispatcher("/x.action");     try {       rd.include(request, myresponse);        string s = myresponse.getoutput();         system.out.println("get response: " + s);     }     catch (exception e) {       e.printstacktrace();     }      ac = actioncontext.getcontext();     system.out.println("after including : action context : " + ac);     response = servletactioncontext.getresponse();     system.out.println("after including : response : " + response);     return "success";   } } 

responseimpl:

testaction2:

public class testaction2 {    public string execute() {     actioncontext ac = actioncontext.getcontext();     system.out.println("in testaction 2 : action context : " + ac);      httpservletresponse response = servletactioncontext.getresponse();     system.out.println("in testaction 2 : response : " + response);     return "success";   } }

this debug info.

• before including: action context :com.opensymphony.xwork2.actioncontext@c639ce
• before including: response : org.apache.catalina.connector.responsefacade@8b677f
• get response: <h1>test!</h1>
• after including : action context : com.opensymphony.xwork2.actioncontext@2445d7
• after including : response : com.bv.test.responseimpl@165547d
• in testaction 2 : action context :com.opensymphony.xwork2.actioncontext@19478c7
• in testaction 2 : response : com.bv.test.responseimpl@165547d

so, have different actioncontext instances before , after including!!

when rd.include request fired internally inside web server. struts point of view sees new request , new action context created result. (that's why need include 'include' thing on struts2 filter.. it's seeing included requests well). since thread local variables used track action context , when actioncontext.getcontext() context related new request (related include) gets retrieved.

did try resetting response initial 1 in block below

try {       rd.include(request, myresponse);        string s = myresponse.getoutput();         system.out.println("get response: " + s);     }     catch (exception e) {       e.printstacktrace();     } {        servletactioncontext.setresponse(response);     } 

if resolves response issue.. store string 's' variable in action context , retrieve inside action2
