Hello,
I do have a problem with forwarding done in CXF.
I have a service implementation like this:
@Path("/foo")
public interface FooSpec {
@GET
Response foo(@QueryParam("bar") String bar, @Context HttpServletRequest
request, @Context HttpServletResponse response);
}
public class Foo implements FooSpec {
@Context
private ServletContext servletContext;
public Response foo(final String bar, final HttpServletRequest request,
final HttpServletResponse response) {
final RequestDispatcher view =
servletContext.getRequestDispatcher("/hello.jsp");
try {
view.forward(request, response);
} catch (Exception e) {
return
Response.serverError().entity(e.getMessage()).build();
}
return null;
}
}
And I am using a JAXRS-Servlet like this:
<servlet>
<servlet-name>JavaServer Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet>
<servlet-name>RestfulApp</servlet-name>
<servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class>
<init-param>
<param-name>jaxrs.serviceClasses</param-name>
<param-value>
org.foo.bar.Foo
</param-value>
</init-param>
<init-param>
<param-name>redirects-list</param-name>
<param-value>([\w/])+.css ([\w/])+.jsp ([\w/])+.faces ([\w/])+.js
([\w/])+.gif ([\w/])+.jpg ([\w/])+.jpeg ([\w/])+.png</param-value> <!--
matches: /images/hello.jpg for example -->
</init-param>
<init-param>
<param-name>redirect-servlet-path</param-name>
<param-value>/</param-value>
</init-param>
<init-param>
<param-name>redirect-servlet-name</param-name>
<param-value>JavaServer Faces Servlet</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RestfulApp</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>JavaServer Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
JSP pages are located at the following location:
/appcontext/*.jsp
REST-services are located at the following location:
/appcontext/rest/*
Ø ISSUE 1
When performing the very first request to this service after deployment, I get
the following exception. This happens only the very first time. After this
exception (on reload), it works well until next re-deployment/restart.
com.sap.engine.services.servlets_jsp.server.exceptions.ServletNotFoundException:
Requested resource [/foo] is not found.
When analyzing this in Firefox, it states, that the request URI is:
http://server:port/appcontext/rest/foo
So the request seem to be valid but for some reason, it looks like the request
would be:
http://server:port/appcontext/foo
But that is not the case.
When checking the other REST services, every single one of them throws this
exception on the very first request. The RequestDispatcher seems to have a
problem on the first request per REST service.
Ø ISSUE 2
When I have done a forwarding to a JSP page, it does keep the /rest context
from the JAXRS servlet, even when I do specify redirect-servlet-name with the
JSP servlet.
So when defining relative links in that JSP page, the do get the /rest part
added to them. So I guess the JAXRS servlet does add its context to the JSP
servlet.
Thank you in advance and best regards,
Marko
