Subject [jira] Closed: (FELIX-574) Replace Action and Render service interfaces by the Servlet interface
Date Mon, 29 Sep 2008 11:24:44 GMT

     [ https://issues.apache.org/jira/browse/FELIX-574?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Felix Meschberger closed FELIX-574.

       Resolution: Fixed
    Fix Version/s: webconsole-1.0.2

The Action and Render interfaces are now deprecated and replaced with the use of the Servlet
API javax.servlet.Servlet interface.

The OSGi Manager listens for registered Servlet services and assumes those with a "felix.webconsole.label"
service registration property to be targeted at extending the Web Console.

In addition an abstract implementation AbstractWebConsolePlugin is provided, which may be
extended to render information or to act upon change requests.

Finally any services registered as Action or Render services are wrapped into proxy servlets
and for the moment still supported.

>             Fix For: webconsole-1.0.2
> The OSGi web console currently defines the Action and Render service interfaces to extend
the console with more functionality. Experience shows that this is probably not the best of
all ideas. In addition, modifying the console to allow for rest-ful URLs (FELIX-566), would
also be more complicated if we keep these interfaces.
> To make it simpler to just plug into the OSGi web console, the Action and Render service
interfaces should be dropped and be replaced by using the javax.servlet.Servlet interface
as the extension point. Any servlets registered with some define service registration property
is taken up by the OSGi web console as an extension employing the white board pattern.
