spring context - webapplication context in restlet 2

[Rahul Juneja-2]

I wanted to get some spring injected beans in my resource file. and i have looked at the integration with spring in other ways but i would not be very interested in that as i want to keep spring separate from restlet. Also i am aware of the concern that this way my application will be tied to Servlet api. but i think i am fine with that as i will be running on tomcat only.

I looked at "SpringServerServlet" and tried calling getWebApplicationContext() or getServletContext() but in both the cases i am getting exception. I did not do anything else. except calling this method from the resource file. Is there any other steps i need to follow to get the springContext or webappllication context to get the beans from the spring.

Any help on this is highly appreciated.

Thanks,

Rahul

getServletContext() inside a servlet is provided by the JEE API.  If  
that's throwing an exception, you have a non-restlet-related problem.

I'm not so familiar with SpringServerServlet, but it appears that it  
is loading the spring application context from the standard (for  
spring) JEE location.  Are you loading the application context using  
ContextLoaderListener?

You might also try out RestletFrameworkServlet.  It allows you to  
configure restlet in approximately the same way you configure Spring  
MVC.

Again, though, if you can't invoke getServletContext() from inside a  
servlet, none of these solutions are going to work for you.

Rhett,

I tried the following things in ServerResource File. anyways thats ok but i have a question about why Restlet doesn't expose the Servlet context which is one of the attributes added to the context of the application. "org.restlet.ext.servlet.ServletContext" ?

Thanks,
Rahul

Do you mean "why doesn't Restlet expose the ServletContext in the  
ServerResource API"?  Because that would create a dependency in  
Restlet core on a JEE class.  Restlet core is designed to run without  
JEE.

Rhett,

But still i guess its good to have an interface or something which can have an implementation in case we are running within the container. maybe inside the jee version of the restlet.

Thanks,

Rahul

Hi Rahul,

 

In Restlet 2.0, the ServletContext is copied into an "org.restlet.ext.servlet.ServletContext" attribute of the Restlet application attached to the ServerServlet. You should be able to retrieve it this way:

 

ServletContext sc = (ServletContext) getContext().getAttributes().get(“org.restlet.ext.servlet.ServletContext”);

 

Let us know if it doesn’t work.

No, it doesn't work.  

I have some spring beans I exported to the servlet context.  In my debugger, I can see that the context.parentContext.attributes does contain my exported beans but I can't get to them through the api.

Hi there,

I've just tried the following code with the latest from SVN trunk:

package test;

import javax.servlet.ServletContext;

import org.restlet.Application;
import org.restlet.Request;
import org.restlet.Response;
import org.restlet.data.MediaType;

public class MyApplication1 extends Application {

    @Override
    public void handle(Request request, Response response) {
        ServletContext sc = (ServletContext)
getContext().getAttributes().get(
                "org.restlet.ext.servlet.ServletContext");

        response.setEntity("hello1: " + sc.getServerInfo(),
                MediaType.TEXT_PLAIN);
    }

}

And it displayed the following in my browser:

        hello1: Apache Tomcat/6.0.18

I guess, you might be using an older version of Restlet without the fix.
Could you try again with a recent snapshot?

Note that while fixing a life cycle issue on 10/28, I broke ServerServlet.
This has just been fixed in SVN trunk today, but this wasn't related to
ServletContext however.

Best regards,
Jerome Louvel
