public class JiraWebworkActionDispatcher extends jakarta.servlet.http.HttpServlet
This is the servlet that invokes WebWork actions and then dispatches to their appropriate view.

This servlet is one of the key planks of JIRA architecture.

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(jakarta.servlet.http.HttpServletRequest httpServletRequest, jakarta.servlet.http.HttpServletResponse httpServletResponse) throws jakarta.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 jakarta.servlet.http.HttpServlet
      Parameters:
      httpServletRequest - HttpServletRequest
      httpServletResponse - HttpServletResponse
      Throws:
      jakarta.servlet.ServletException
      IOException
