Thanks

hi

To bypass some of the interceptors in the default stack.

Create your own interceptor stack and add what interceptors you want to the stack .
As you can also struts 2 by default is providing lot of stacks. you can see all the stacks in struts-default.xml

I put the following code in struts.xml

<interceptors>
					<interceptor-stack name="MyOwnStack">
					                <interceptor-ref name="servletConfig"/> 
					                <interceptor-ref name="prepare"/>
					                <interceptor-ref name="chain"/>
					                <interceptor-ref name="checkbox"/>
					                <interceptor-ref name="staticParams"/>
					                <interceptor-ref name="params">
					                                <param name="excludeParams">dojo\..*</param>
					                </interceptor-ref>
					                
					                <interceptor-ref name="conversionError"/>
					                <interceptor-ref name="validation">
					                    <param name="excludeMethods">input,back,cancel,browse</param>
					                </interceptor-ref>
					                <interceptor-ref name="workflow">
					                    <param name="excludeMethods">input,back,cancel,browse</param>
					                </interceptor-ref>
					</interceptor-stack>
		</interceptors>

		<default-interceptor-ref name="MyOwnStack"/>

Does the above lines of code ensure that only the above interceptors are invoked? How will I verify that?

That's just how S2 works--only interceptors in stacks being used are called.

Facing the same problem..

instead of controlling it at configuration level, I want to bypass the execution of Action/next interceptors in the stack .. is it really possible ?
Let me explain my problem in detail here..

I need to check a cookie at interceptor and need to execute different actions based on cookie value.. I tried in below way, I am able to redirect the response to desired action and page but with exceptions. Here is the code ..

if(cookieExists==false){				
 
   response.sendRedirect(differntUrl);
   return null; 
}
return invocation.invoke();

Error Message
java.lang.IllegalStateException: Cannot create a session after the response has been committed
org.apache.catalina.connector.Request.doGetSession(Request.java:2301)
