I received outstanding guidance yesterday on integrating wicket-spring into my
application and combined with the write-up along with a lot of other similar
articles/blogs I found online, I'm confident I'm on the right track. I have
encountered an error that has me a little mystified and was hoping someone
could help shed some light. I'm getting the following exception when I attempt
to start Tomcat within Eclipse:
java.lang.IllegalStateException: bean of type
[org.apache.wicket.protocol.http.WebApplication] not found
Full stack trace below.
Despite having defined my WebApplication bean in the applicationContext.xml,
this exception appears at start-up, leading me to believe that it cannot find
my applicationContext.xml configuration, though I feel that I'm pointing Spring
and Wicket in the right direction with the following:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
I have also adjusted my filter to leverage SpringWebApplicationFactory as
follows:
<filter>
<filter-name>wicket.wicketFilter</filter-name>
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
<init-param>
<param-name>applicationFactoryClassName</param-name>
<param-value>org.apache.wicket.spring.SpringWebApplicationFactory</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>wicket.wicketFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
And in my applicationContext.xml, my WebApplication bean has been defined:
<bean id="wicketApplication" class="com.oa.frontoffice.FrontOfficeApp" />
Lastly, I have the following in my init() method on the WebApplication object:
getComponentInstantiationListeners().add(new SpringComponentInjector(this));
Has anyone encountered this exception before who can offer me some advice on
where to start digging?

Then you probably don't use wicket-spring. Or you store your app context in a
Wicket component, e.g., a page.
The "official" documentation is
https://cwiki.apache.org/confluence/display/WICKET/spring.html
IMHO it's problematic because it tells you first about things you don't want to
use.
There's a chapter in the new free Wicket guide, but it's very basic as well.
So, here's my method / recommendation:
