struts.action.excludePattern not working,

Question

struts.action.excludePattern is not working for me in Struts 2, i had place servlet cal in form action, form will submit on hyperLink click.

struts.xml:

<constant name="struts.action.excludePattern" value="/PunchoutOrder"/>

web.xml

  <servlet>
    <description></description>
    <display-name>PunchoutOrder</display-name>
    <servlet-name>PunchoutOrder</servlet-name>
    <servlet-class>com.PunchoutOrder</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>PunchoutOrder</servlet-name>
    <url-pattern>/PunchoutOrder</url-pattern>
  </servlet-mapping>

jsp:

<form id="form1" name = "form1" method="post" action="PunchoutOrder">
<input type="image" alt="Submit" src="images/submit.png" onclick="Submit(form1);return false;"/>

Getting below Error:

15:26:37,512 WARN  [Dispatcher] Could not find action or result
There is no Action mapped for namespace / and action name PunchoutOrder. - [unknown location]

Answer 1

I was having the same problem and ran into several hints at how to fix it. However the solution I found, at least in Struts 2.2.2 was that I was using the wrong filter in my web.xml. After some digging through Google and SO posts I found that changing from:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

To:

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

After changing the filter, my exclusion pattern constant in the struts.xml immediately started functioning as expected.

This is also documented here: https://cwiki.apache.org/confluence/display/S2WIKI/Troubleshooting+guide+migrating+from+Struts+2.0.x+to+2.1.x#TroubleshootingguidemigratingfromStruts2.0.xto2.1.x-FilterMapping%2CdefaultActionextensions%2CandServlets

Although the previous entry says to explicitly declare the action extensions, I found it was unnecessary after fixing my filter declaration.

Answer 2

it seems as if your syntax isn't entirely correct. I fell upon the same issue and correcting the regular expression worked for me. After adding the line

<constant name="struts.action.excludePattern" value="/exclude/.*?"/>

to my struts.xml, everything works as expected. Request within this path are now returned with 404 errors instead of struts error message "There is no Action mapped for namespace ..."
