Question

Using Spring and Struts together gives no error
message in the console, but only a:

HTTP Status 404 – Servlet action is not available

in the Browser.

The logs give no clue whatsoever.

Answer 1

When Struts’ action servlet fails to startup for whatever reason,
the resulting error can be as above.

In my case – struts using springs spring-struts integration –
the necessary spring jars (esp. spring-struts) were missing from the
class path of my web application.

The following maven dependencies worked:

    <properties>
    <spring.maven.artifact.version>
        3.0.3.RELEASE
    </spring.maven.artifact.version>

    <spring.security.maven.artifact.version>
        3.0.3.RELEASE
    </spring.security.maven.artifact.version>

Note: if you don’t use spring-security you can very likely drop the spring-security related dependencies, also the exclusion in spring-struts was necessary to include the latest struts version instead of 1.2.9
