Struts 2.3 ignores wildcard actions

1.4k views Asked by At

I'm setting up an application that uses Struts 2.3 and Tiles 2. Some pages will be heavily Struts driven (e.g. lots of CRUD) while others will be simple, static HTML/JSP pages. I want to set up some actions that handle specific functionality and send all other URLs to a default action, which will check to see if the appropriate static page exists based on the supplied path. If not, a 404 error or some such will be generated instead.

In struts.xml, I have applied a basic configuration that appears like it should work; however, Struts seems to ignore the wildcard action. The non-wildcard actions work just fine.

Here's the struts.xml:

<?xml version="1.0" encoding="UTF-8"?>

    <package name="main" extends="base" namespace="/">
        <action name="login">

        </action>
    </package>
    <!-- package end -->
 
</struts>

And here's an example of the error I receive:

What am I missing or doing wrong?

Since you are using advanced wildcards then your action name should be a valid regex expression to match the configuration.

Like so

<action name="{.*}" class="com.installation.action.PageAction">
   <result type="tiles">standard-page</result>
</action>
