RE: Spring-loaded Restlets with Context dependencies
Hi Dustin, Thanks for reporting your solution and for the support! I'm sure it will help others. Regarding the WAR client, it is normally automatically added by the ServerServlet#createComponent() method, which is invoked at the end of SpringServerServlet#createComponent. No need to declare it anymore.

I'm using the org.springframework.beans.factory.config.PropertyPathFactoryBean class to provide a Context to my component, which is now defined in Spring: !-- Component. This will be loaded by the Servlet according to the web.xml definition of org.restlet.component -- bean name=component class=org.restlet.ext.spring.SpringComponent property name=defaultTarget ref=application / property name=context ref=component.context / property name=clientsList list valuehttp/value valuefile/value /list /property /bean !-- Context -- bean name=component.context class=org.springframework.beans.factory.config.PropertyPathFactoryBean / I had to override the SpringServerServlet.createComponent() method to add a ServletWARClient to the Spring loaded component since simply declaring 'war' in the clientsList is not sufficient. The ServletContext is required to build one of those Clients. I need the WAR protocol to load my FreeMarker Templates from my WAR, as well as my CSS and JavaScript files. I hope I did this in the best way possible and didn't miss something simple that prevented me from doing the extra work. Maybe this will help someone else! Thanks to the Restlet team for everything. I am enjoying myself none the less. Dustin Dustin N. Jenkins wrote: All, I'm using the 1.2 (2.0) snapshot with JDK 1.6. All of my beans are loaded by Spring. This is working really lovely for the most part, except for any bean that relies on the Context to be passed in. How do we create ChallengeGuards, for example, in Spring, when we don't have a Context to pass to it? I used to override the default Constructor to use a Restlet instead of a Context, which would act as a Parent and I could call getContext() from that bean. That Parent bean used to be the Application, which is initialized by the SpringServerServlet. The problem is that Spring is loading in all the beans first, which means the Parent's Context is null, which used to be alright prior to 2.0. What is the solution for this problem? Do I need to create a Spring Component around my Application? I don't use a Component now, only an Application. Thanks! Dustin -- Dustin N.

RE: Can a filter read entity non-destructively?
Hi Keith, Did you know we have already ported those examples? Check the org.restlet.example module for source code. Otherwise, the getEntityAsForm() method caches the result by default, so you could invoke it again later down the road. However, the Resource class doesn't know about that and from its point of view, the original entity isn't available anymore. One way to workaround this is to replace the Request's entity with the parsed Form: request.setEntity(myForm.getWebRepresentation()); Best regards, Jerome Louvel -- Restlet ~ Founder and Lead developer ~ http://www.restlet.org Noelios Technologies ~ Co-founder ~ http://www.noelios.com -Message d'origine- De : Keith McDonald [mailto:keithmmcdon...@gmail.com] Envoyé : mardi 12 mai 2009 18:06 À : discuss@restlet.tigris.org Objet : Can a filter read entity non-destructively? To teach myself Restlet, I am trying to port the example bookmarking application from chapter 7 of Richardson and Ruby's RESTful Web Services. In their example, they put before filters on their objects to check if the user whose information is being requested matches the user whose credentials were used to authenticate. It does this by looking at the user name in the entity. I tried to recreate this functionality in Restlet by creating a subclass of Filter called MustSpecifyUserFilter and reading the entity by calling getEntityAsForm inside the filter's beforeHandle method, but this causes the entity to be marked as unavailable and a 400 to be returned before my Resource code can process it (In my Resource subclass, I am only overriding storeRepresentation rather than handlePut). Should I give up trying to use Filters to recreate this functionality or is there another way such as overriding handlePut to ignore the available attribute on the entity?

RE: SiteMesh-like functionality for Restlet?
Hi Rhett, For very similar purpose, we rely on FreeMarker at Noelios and are extremely happy with it. It is easy to define and reuse HTML layout macros. I suggest having a look at their manual: http://www.freemarker.org/docs/index.html Their mailing list is also quite reactive. Another option is Velocity for which we also have a Restlet extension.

Hi, So far I've been using Restlet for API-only functionality -- resources that only have XML and/or JSON representations. Now I'm thinking about using it for the HTML interface for a project. One tool which I've always used to help with web GUIs is SiteMesh ( http://www.opensymphony.com/sitemesh/ ), which is a filter which decorates the pages generated for individual views with the common elements for your site (e.g., navigation), decoupling your site layout from the content of individual pages. SiteMesh works very well, but unfortunately it is an actual JEE servlet filter and seems to rely heavily on JEE APIs. I'm considering using Restlet to render the GUI for this project in order to decouple it from JEE, so SiteMesh is probably out. (I haven't looked closely at the source to see if the JEE stuff could be factored out, but that's an option if there's no better way.) I've looked around a bit, but I haven't found an equivalent that works with Restlet. (I found a page about using freemarker macros to emulate layouts, but that's the closest I've come.) Does anyone have any solutions for handling HTML layouts with Restlet that they particularly like?
