Q:

Case Sensitivity of Action Names in Struts 2

Is there an easy way to make Struts 2 action names case insensitive? Currently I have the following action defined:
<action name="printTest" class="MyClass" >
  <result name="error">/WEB-INF/jsp/error.jsp</result>
  <result name="input">/WEB-INF/jsp/test.jsp</result>
  <result name="success">/WEB-INF/jsp/test.jsp</result>
</action>

If the user types URL /app/printtest.do instead of  /app/printtest.do this action is not executed. 
Other then mod_rewrite on the httpd level or something like that, the only option that I know about right now is simply adding the same exact action and changing the name to printtest. Ideally it would be a simple config change to struts.xml.

A:

No configurable option, AFAIK, for case insensitive mapping. 
So, I believe  you have answered the question yourself: either Apache's mod_rewrite, or write the extra mappings in the config.
You could also write your own ActionMapper, extending DefaultActionMapper (method
parseNameAndNamespace() ),  but I suspect it would be overkill... :-)
