Re: Problem with Url redirection

[Thierry Boileau]

Hello Murilo, could you tell us what is the variable called "context"? A call to "getContext()" should be sufficient since it represents the context of the application. Could you tell us how the EsbApplication is used? In a Component? Best regards, Thierry Boileau -- Restlet ~ Core developer ~ http://www.restlet.org Noelios Technologies ~ Co-founder ~ http://www.noelios.com Hi, After I got the redirection class working I tried to modify to work on mule (www.mulesource.org) On my my example I just create a class and that's it. But mule needs a class which extends org.restlet.Application, and my problems started again. This is my class: public class EsbApplication extends Application {     @Override     public Restlet createRoot() {                      Router router = new Router(context);         router.attach(new Redirector(context, "https://services.dev{rr}",                 Redirector.MODE_DISPATCHER));                 return router;     } } When I do the request I received this exception. 0-Nov-2008 17:51:57 org.restlet.Redirector handle INFO: Redirecting via client connector to: https://services.dev/services/users 10-Nov-2008 17:51:57 com.noelios.restlet.StatusFilter getStatus SEVERE: Unhandled exception or error intercepted java.lang.NullPointerException     at org.restlet.Redirector.redirectDispatcher(Redirector.java:244)     at org.restlet.Redirector.handle(Redirector.java:217)     at org.restlet.Filter.doHandle(Filter.java:150)     at org.restlet.Filter.handle(Filter.java:195)     at org.restlet.Router.handle(Router.java:504)     at org.restlet.Filter.doHandle(Filter.java:150)     at org.restlet.Filter.handle(Filter.java:195)     at org.restlet.Filter.doHandle(Filter.java:150)     at org.restlet.Filter.handle(Filter.java:195)     at org.restlet.Filter.doHandle(Filter.java:150)     at com.noelios.restlet.StatusFilter.doHandle(StatusFilter.java:130)     at org.restlet.Filter.handle(Filter.java:195)     at org.restlet.Filter.doHandle(Filter.java:150)     at org.restlet.Filter.handle(Filter.java:195)     at com.noelios.restlet.ChainHelper.handle(ChainHelper.java:124)     at com.noelios.restlet.application.ApplicationHelper.handle(ApplicationHelper.java:112)     at org.restlet.Application.handle(Application.java:341)     at org.restlet.Uniform.handle(Uniform.java:108)     at org.mule.transport.restlet.RestletComponent$RestletCallable.onCall(RestletComponent.java:44) So.. I looked the Redirector's source on the line 244 and the line is... ->  getContext().getClientDispatcher().handle(request, response); So... I tried to create a context with this lines before create the redirector, but without success. Context context = new Context(); Context.setCurrent(context); I think it was a mule's problem, but I need to solve this to continue my implementation.

So.... I got the successful redirection. I use this class. public class Test {     public static void main(String[] args) throws Exception {         // Create a component         Component component = new Component();         component.getServers().add(Protocol.HTTP, 8182);         component.getClients().add(Protocol.HTTP);         component.getDefaultHost()                 .attachDefault(                         new Redirector(component.getContext(),                                 "http://services.dev{rr}",                                 Redirector.MODE_DISPATCHER));         component.start();     } } I had to modify one thing, I have to use "http://services.dev{rr}" without the '/' before '{rr}' because it was redirecting with two '/', like this: http://services.dev//services/users. Now, I'm trying integrate this application with Mule, but I think I'll need change this code because mule expect classes extending org,restlet.Application. I'll try modify the standalone class to extend Application and after this integrate with mule.
