Spring Portlet MVC 3.0 Release : File not found: /WEB-INF/servlet/view

[chengkhoon]

I have written a simple HelloWorld portlet with Spring 3 Portlet MVC and deploy to Vignette Portal Server and it throws errors with the following stack trace:
ERROR - DispatcherPortlet - Could not complete request
javax.portlet.PortletException: javax.servlet.ServletException: File "/WEB-INF/servlet/view" not found

at org.springframework.web.portlet.FrameworkPortlet.p rocessRequest(FrameworkPortlet.java:522)
at org.springframework.web.portlet.FrameworkPortlet.d oDispatch(FrameworkPortlet.java:470)

Notes:
When I switch to Spring 2.5.6 with the same source code, it works fine.
Any help would be appreciated. I'm hereby attached the detail logs for further investigation.
Here is my environment:
jdk 1.6.0_17, spring 3.0.1, Tomcat 6.0.20, Vignette Portal Server 7_4

The ViewRendererServlet Mapping is reside in web.xml:
<servlet>
<servlet-name>view-servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.ViewRenderer Servlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>view-servlet</servlet-name>
<url-pattern>/WEB-INF/servlet/view</url-pattern>
</servlet-mapping>

I really need some leads about whether is a bug from Vignette Portal or from Spring 3. It's just work fine in Spring 2.5.6.
Is there a workaround ? Otherwise I have to bypass Spring Portlet MVC and just implement with GenericPortlet.

Looking at the stack trace it appears to be entering the ViewRendererServlet but is failing somewhere in the Tomcat JspServlet, so my guess would be that either the viewResolver configuration is incorrect or the jsp is missing/invalid. Can you post the full web.xml, application context files (both applicationContext.xml and helloWorld-portlet.xml, and /WEB-INF/jsp/helloWorld.jsp.

[cmelgar]

I have a feeling this is probably a bug in Vignette Portal. The log shows the viewResolver is correctly generating the jsp path, and the stacktrace message indicates the JspServlet is trying to find /WEB-INF/servlet/view instead of /WEB-INF/jsp/helloWorld.jsp. This is a real possibility if the PortletRequestDispatcher doesn't setup the correct context for the included servlet/jsp (including provide a correct implementation of the servlet RequestDispatcher). I'm speculating here, but since Spring 3.x supports JSR 286, but Spring 2.5.x doesn't, it is possible that the portlet container is behaving differently once you use the updated Spring jar files.

You could easily check this independent of Spring by creating a GenericPortlet that does an include on a Servlet that does an include on a jsp. You could also see if it makes any difference whether you do this as a JSR168 or JSR286 portlet.

make changes similar to the following:

web.xml

<servlet-mapping>
     <servlet-name>ViewRendererServlet</servlet-name>
     <url-pattern>/whoSucksForNotMappingWebInfUrls</url-pattern>
</servlet-mapping>

Add the following to portlet.xml

<init-param>
     <name>viewRendererUrl</name>
     <value>/whoSucksForNotMappingWebInfUrls</value>
</init-param>

Yes, this sucks because you are mapping a freely accessible URL, but that is all you have available.

Hi,
i am using the same environment, and i think that i have the same problem.

Could you tell me if you solved it? and how did you solve?


thanks a lot

See the instructions above. Basically, map it to a URL that is NOT under WEB-INF.
