public class JiraServletDispatcher

extends HttpServlet

Main dispatcher servlet. It works in three phases: first propagate all parameters to the command JavaBean. Second, call execute() to let the JavaBean create the result data. Third, delegate to the JSP that corresponds to the result state that was chosen by the JavaBean. The command JavaBeans can be found in a package prefixed with either of the package names in the comma-separated "packages" servlet init parameter.

public void service(HttpServletRequest aRequest,

             throws 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.

Parameters:

aRequest -

aResponse -

ServletException
