Malcolm Edgar commented on CLK-564:
-----------------------------------
I was thinking that the ResourceService would cache the resources internally
with the realpath overriding any JAR resources.
Glassfish 3.0 sounds nice.
Presumably on the Servlet 3.0, this service wouldn't be needed used so we
simply would not map the ClickServlet to handle /click/* requests.
What do you think about migrating our the META-INF/web to META-INF/resources,
we could have the XmlConfigService and ResourceService also support
META-INF/web for backward compatibility.
> Add ResourceService for serving static resources

> Key: CLK-564
> URL: https://issues.apache.org/jira/browse/CLK-564
> Project: Click
> Issue Type: New Feature
> Components: core
> Affects Versions: 2.1.0
> Reporter: Malcolm Edgar
>
> The Click static resource deployment strategy of writing *.htm, *.css and
> image files to the web application /click/ directory does not work on all
> application servers. In particular WebLogic and WebSphere have security
> restrictions which prevent this from occuring. In these scenarios users are
> have to deploy these applications to the WAR file at build time. Google GAE
> also does not support this deployment mode.
> A solution to this problem is to use the ClickServlet to serve these
> resources. By adding an additional web.xml mapping:
> <servlet-mapping>
> <servlet-name>ClickServlet</servlet-name>
> <url-pattern>/click/*</url-pattern>
> </servlet-mapping>
> The ClickServlet could use a ResourceService interface obtained from the
> ConfigService which returns the resource data. A default ClickResourceService
> would be provided which loads all the resources at application initialization
> time. This service would scan all the JAR files for resources in META-INF/web
> as is currently done in XmlConfigService and would cache them in memory. The
> service would also scan all the resources under the WAR /click/ directory.
> These resources would override any defined in the application JAR files.
> This could be a good feature for 2.1.0, we should possibly delay the 2.1.0 RC
> release to include this feature.
