Hello,
I'm trying to run simple Spring web app with DispatcherServlet
web.xml
<servlet>
<servlet-name>resteasy</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>resteasy</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
----------------------------------------------------
resteasy-servlet.xml
<!-- Import basic SpringMVC Resteasy integration -->
<import resource="classpath:springmvc-resteasy.xml"/>
<!-- the only @Path entity -->
<bean class="com.xx.xx.xx.Devices"></bean>
----------------------------------------------------
I have

AFAIget the core issue is the absence of Registry in a context map:
LinkDecorator.java
....
public void beforeMarshal(Object entity) {
UriInfo uriInfo =
ResteasyProviderFactory.getContextData(UriInfo.class);
ResourceMethodRegistry registry =
(ResourceMethodRegistry)
ResteasyProviderFactory.getContextData(Registry.class);
!!!!!! registry==null here
// find all rest service classes and scan them
RESTUtils.addDiscovery(entity, uriInfo,
registry);
Unfortunately I can't find the place where Registry should be inserted
into the context map.
But it's definitely not in org.jboss.resteasy.core.SynchronousDispatcher:441
public void pushContextObjects(HttpRequest request, HttpResponse response)
{
Map contextDataMap = ResteasyProviderFactory.getContextDataMap();
contextDataMap.put(HttpRequest.class, request);
contextDataMap.put(HttpResponse.class, response);
contextDataMap.put(HttpHeaders.class, request.getHttpHeaders());
contextDataMap.put(UriInfo.class, request.getUri());
contextDataMap.put(Request.class, new RequestImpl(request));
contextDataMap.putAll(defaultContextObjects);
}
Does anybody use DispatcherServlet?
