Setting up the servlets etc. for RPC on Guice 2

[sondresb]

Hi,

As I mentioned briefly in another thread, I wanted to share the set-up I used to get the servlets and filters configured in a Guice 2 webapp. Here goes:

            /** Sets up filters and servlets for Smart GWT RPC. */
            private void configureSmartGWTRPC() {
                //since we cannot annotate third party lib, bind them here in singleton scope
                this.bind(IDACall.class).in(Scopes.SINGLETON);
                this.bind(FileDownload.class).in(Scopes.SINGLETON);
                this.bind(DataSourceLoader.class).in(Scopes.SINGLETON);
                this.bind(Init.class).in(Scopes.SINGLETON);
                this.bind(CompressionFilter.class).in(Scopes.SINGLETON);

                //set up URLs to be served by Smart GWT servlets
                serve("/sc/init").with(Init.class);//URL not used, but simulates load-on-startup (Guice uses order from here)
                serve("/sc/IDACall*").with(IDACall.class);//had to remove "/" before * compared to sample project to avoid a 404 message
                serve("/sc/DataSourceLoader").with(DataSourceLoader.class);
                serve("/sc/skins/*").with(FileDownload.class);
                serve("/sc/system/modules/*").with(FileDownload.class);
                serve("/sc/system/development/*").with(FileDownload.class);
                serve("/sc/system/reference/skin/*").with(FileDownload.class);

                //add the filter that behaves more or less like mod_deflate
                filter("/sc/*").through(CompressionFilter.class);
            }

Hope someone finds this useful.

PS. This is replacing any web.xml config for SmartGWT, only the Guice context listener to set up the module + the guice filter will be there.
