All Implemented Interfaces:

Serializable, Servlet, ServletConfig

public class ReflexServlet
extends HttpServlet

ReflexServlet is a servlet for the RefleX engine that implements the Web module specification for Active Tags.

All path used in the deployment descriptor (web.xml) MUST use the web URI scheme to denote a path relative to this web application (web:///WEB-INF/myResource). The Active Sheet itself also support the web scheme.

Servlet init parameters

<servlet>
    <init-param>...

Name	Value	Default
activeSheetPath	The path to the Active Sheet.	web:///WEB-INF/active-sheet.web
catalogs	A list of catalogs paths separated with whitespaces. URIs supported include the web URI scheme and the special res URI scheme for precompiled catalog classes.

Context init parameters

<web-app>
    <context-param>...

Name	Value	Default
driver-class	A list of driver class names, separated with whitespaces. When initializing, the servlet just calls Class.forName(...) for each driver.

Deployment

This servlet may be safely deploy to a sharable location without any special precaution, except that the VFS library must be handled by the same class loader than the RefleX library (that is to say they must be deployed either in the webapp library directory or in the servlet engine shared-libraries directory, but must not be separated).
