Class ScriptServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          groovy.servlet.AbstractHttpServlet
              com.shift.framework.servlet.ScriptServlet

All Implemented Interfaces:

groovy.util.ResourceConnector, java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class ScriptServlet
extends groovy.servlet.AbstractHttpServlet

This servlet will run Groovy scripts as Groovlets. Groovlets are scripts with these objects implicit in their scope:

• request - the HttpServletRequest
• response - the HttpServletResponse
• application - the ServletContext associated with the servlet
• session - the HttpSession associated with the HttpServletRequest
• out - the PrintWriter associated with the ServletRequest

Your script sources can be placed either in your web application's normal web root (allows for subdirectories) or in /WEB-INF/groovy/* (also allows subdirectories).

To make your web application more groovy, you must add the GroovyServlet to your application's web.xml configuration using any mapping you like, so long as it follows the pattern *.* (more on this below). Here is the web.xml entry:

       <servlet>
         <servlet-name>Groovy</servlet-name>
         <servlet-class>groovy.servlet.GroovyServlet</servlet-class>
       </servlet>
   
       <servlet-mapping>
         <servlet-name>Groovy</servlet-name>
         <url-pattern>*.groovy</url-pattern>
         <url-pattern>*.gdo</url-pattern>
       </servlet-mapping>
 

The URL pattern does not require the "*.groovy" mapping. You can, for example, make it more Struts-like but groovy by making your mapping "*.gdo".
