This is the servlet that invokes WebWork actions and then dispatches to their appropriate view.

This code was copied from the webwork ServletDispatcher originally and has since diverted some what for JIRA purposes. We no longer share any code.

service

public void service(javax.servlet.http.HttpServletRequest httpServletRequest,

             throws javax.servlet.ServletException,
                    IOException

Service a request. The request is first checked to see if it is a multi-part. If it is, then the request is wrapped so WW will be able to work with the multi-part as if it was a normal request. Next, we will process all actions until an action returns a non-action which is usually a view. For each action in a chain, the action's context will be first set and then the action will be instantiated. Next, the previous action if this action isn't the first in the chain will have its attributes copied to the current action.

Overrides:

service in class javax.servlet.http.HttpServlet

Parameters:

httpServletRequest - HttpServletRequest

httpServletResponse - HttpServletResponse

Throws:

javax.servlet.ServletException

IOException
