I currently have my
web.xml configured to catch 404s and send them to my spring controller which will perform a search given the original URL request.
The functionality is all there as far as the catch and search go, however the trouble begins to arise when I try to return a view.
<bean class="org.springframework.
web.servlet.view.ContentNegotiatingViewResolver" p:order="1">
<property name="mediaTypes">
<map>
<entry key="json" value="application/json" />
<entry key="jsp" value="text/html" />
</map>
</property>
<property name="defaultContentType" value="application/json" />
<property name="favorPathExtension" value="true" />
<property name="viewResolvers">
<list>
<bean class="org.springframework.
web.servlet.view.BeanNameViewResolver" />
<bean id="viewResolver" class="org.springframework.
web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value="" />
</bean>
</list>
</property>
<property name="defaultViews">
<list>
<bean class="org.springframework.
web.servlet.view.json.MappingJacksonJsonView" />
</list>
</property>
<property name="ignoreAcceptHeader" value="true" />
</bean>
This is a snippet from my MVC config file.
The problem lies in resolving the view's path to the /WEB-INF/jsp/ directory. Using a logger in my JBoss setup, I can see that when I test this search controller by going to a non-existent page, the following occurs:
Server can't find the request
Request is sent to 404 error page (in this case my search controller)
Search controller performs search
Search controller returns view name (for this illustration, we'll assume test.jsp is returned)
Based off of server logger, I can see that org.springframework.
web.servlet.view.JstlView is initialized once my search controller returns the view name (so I can assume it is being picked up correctly by the InternalResourceViewResolver)
Server attempts to return content to
browser resulting in a 404!
A couple things confuse me about this:
I'm not 100% sure why this isn't resolving when test.jsp clearly exists under the /WEB-INF/jsp/ directory.
Even if there was some other problem, why would this result in a 404? Shouldn't a 404 error page that results in another 404 theoretically create an infinite loop?
Thanks for any help or pointers!
