Question

I recently switched one of my static html files to a Spring controller that uses a JSP to render its view. I use jetty to test locally and local testing shows the page rendering fine. Upon deploying to our test server, which uses Tomcat 6.0.26, I get the following exception:

javax.servlet.ServletException: Could not get RequestDispatcher for [/WEB-INF/jsp/index.jsp]: check that this file exists within your WAR
    org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:219)
    org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:250)
    org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1060)
    org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:798)
    org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716)
    org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

I have confirmed that the JSP exists in the war I deploy and the exploded directory that tomcat creates upon deployment. Here is what my web.xml and front-controller-servlet.xml files look like respectively (web.xml shorted slightly):

front-controller-servlet.xml:

            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        </bean>
    </beans>

The difference between my dev instance and test instance is that the dev instance is deployed to the root (localhost/search.html) whereas the test instance is deployed to server.com/appname/search.html. Appname is the name of the *.war file I deploy. I have tried adding the full path as the prefix to the jps files (/appname/WEB-INF/jsp/) and a number of other combinations with no luck. I have verified that the jsp-api jars are in the tomcat lib directory. My tomcat install is the basic/default install.

Answer 1

The issue was caused by the default jsp servlet being removed from the default web.xml of the tomcat install. This had been done by a former co-worker and not to my knowledge. Replacing the test server’s web.xml with the default web.xml (which included url-patterns/servlets for handling jsp files) corrected the issue.
