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.

Method Detail

init

public void init(javax.servlet.ServletConfig config)
          throws javax.servlet.ServletException
Initialize dispatcher servlet

Specified by:
init in interface javax.servlet.Servlet
Overrides:
init in class javax.servlet.GenericServlet
Parameters:
config - ServletConfig
Throws:
javax.servlet.ServletException

service

public void service(javax.servlet.http.HttpServletRequest httpServletRequest,
                    javax.servlet.http.HttpServletResponse httpServletResponse)
             throws javax.servlet.ServletException
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

getHTMLErrorMessage

protected String getHTMLErrorMessage(Throwable t)
Return an HTML error message for the throwable

Parameters:
t - Throwable
Returns:
A String with an error message
