Hi All
>From looking in the archives (and not finding what I was looking for)
I have a feeling I may be about to open a can of worms and possibly
leave myself open to abuse. Please go gently with me.
I've managed to get GWT integrated into Spring MVC when deployed to a
real tomcat server. I've configured web.xml to redirect urls to Spring
and then an MVC class passes back my GWT page as a view. It works
well! But not in hosted mode.
This is how I've got the hosted mode
(<project>\tomcat\webapps\ROOT\WEB-INF) web.xml configured:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>shell</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>shell</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
and the shell-servlet.xml looks like this:
<bean name="gwtShellServlet" class="co.uk.marauder.SpringGWTShellServlet"/>
<bean name="messageImpl" class="co.uk.marauder.server.MessageImpl">
<constructor-arg value="What's up doc?"/>
</bean>
<bean id="urlMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<map>
<entry key="/co.uk.marauder.MyApplication/**/*"
value-ref="gwtShellServlet" />
<entry
key="/co.uk.marauder.MyApplication/rpc/Message"
value-ref="messageImpl" />
</map>
</property>
</bean>
SpringGWTShellServlet basically takes GWTShellServlet and makes it
into a Spring Controller:
public class SpringGWTShellServlet extends GWTShellServlet implements
Controller, ServletContextAware
{
private static final long serialVersionUID = 6499284524261360631L;
private ServletContext servletContext;
@Override
public ModelAndView handleRequest(HttpServletRequest
request,HttpServletResponse response) throws Exception
{
this.doPost(request, response);
return null;
}
@Override
public void setServletContext(ServletContext servletContext)
{
this.servletContext = servletContext;
}
@Override
public ServletContext getServletContext()
{
return servletContext;
}
}
It works if I have a simple RPC service interface (e.g. a single
method that returns a string), but anything more complicated, like
passing back a List of user defined objects doesn't.
In both cases I get the error:
[INFO] StandardContext[]ERROR: The serialization policy file
'/co.uk.marauder.MyApplication/5BA8A5B3E35F40698BB0BF65F390BCF2.gwt.rpc'
was not found; did you forget to include it in this deployment?
[INFO] StandardContext[]WARNING: Failed to get the SerializationPolicy
'5BA8A5B3E35F40698BB0BF65F390BCF2' for module
'http://localhost:8888/co.uk.marauder.MyApplication/'; a legacy, 1.3.3
compatible, serialization policy will be used. You may experience
SerializationExceptions as a result.
I'm assuming my problem is that my server side RPC class is no longer
accessed via GWTShellServlet...?
Has anyone else tried this or know how I can fix it? Or do I have the
wrong approach?
