Class ServletPathMapper

  • All Implemented Interfaces:
    Command, Filter
    public class ServletPathMapper
extends LookupCommand
implements Command

    Command that uses the "servlet path" component of the request URI to select a Command from the appropriate Catalog, and execute it. To use this command, you would typically map an instance of ChainProcessor to an extension pattern like "*.execute" and then arrange that this is the default command to be executed. In such an environment, a request for a context relative URI of "/foo.execute" would cause the "/foo.execute" command to be loaded and executed.
