Comments on: Configuring DWR 3.0 with spring using annotations

I’m trying to make this work with Spring 3.0.3’s mvc:annotation-driven approach, but have failed so far with exception:

javax.servlet.ServletException: No adapter for handler [org.directwebremoting.spring.DwrController@36d2b3]: Does your handler implement a supported interface like Controller?

The problem is that with mvc:annotation-driven directive, only classes annotated with @Controller stereotype can act as controllers in Spring, but it seems that DwrController is not annotated with @Controller.

Any workaround for this? (aside from modifying the dwr framework to add @Controller to class DwrController)

Thanks,

Enrico

Well, has been a while since this post, but there wasn’t really any other source for this. The problem is (I think) that the bean is defined in two different contexts. I moved everything from the global applicationContext.xml to [..]-servlet.xml, and now it works.

Excellent guide to get me up and running,

1 comment though was that the section “Next comes the configuration required by the DispatcherServlet, :” states to update dwrexample-servlet.xml, I found that I needed to put these updates in the /WEB-INF/applicationContext.xml file referenced from the web.xml.

I want to use Spring 3 and dwr 3 and their annotated capabilities. I set all spring properties (web.xml , servlet) , annotate controllers.

When I want to use DWR with annotations integrated in spring i get :

java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: Duplicate name found. See logs for details.
at org.directwebremoting.spring.SpringConfigurator.configure(SpringConfigurator.java:143)
…………….
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘DwrAnnotationURLMapper’: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘__dwrController’: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: Duplicate name found. See logs for details.

I can’t find solution.

Hi,

I integrate DWR 3.0 with Spring 2.5 and its working fine for me. Now I am looking for ExtJs with DWR and Spring. Can anybody tell me how can I do that. I already done a mock example but I am not pretty sure about it. If any one have any idea please share it.

I already done it with DWR 2 and Spring 2.5. But I am looking it with DWR 3 and Spring MVC. If you guys have any idea please share it.

I add configuration on applicationContext.xml as describe below :

dwrController

Than i kick url : http://localhost:8084/SpringMVCItemCategoryWiringAnnotationDWR/dwr
Viola now I have list about classes known to DWR. But none class controller on there even I already mark with @RemoteProxy and @RemoteMethod.
Error message as describe on my previous comments.
Any ideas?

I’ve just migrating from DWR 2 into DWR 3.0.
I follow as you describe and viola when I kick url

I’ve got message on page ” Error: java.lang.SecurityException: No class by name: ItemController”.

Any ideas? since I already map using @Controller in my bean.

Rgds,
Aries
