public class JiraServletDispatcher
extends javax.servlet.http.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.

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 aRequest,
                    javax.servlet.http.HttpServletResponse aResponse)
             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:
aRequest - HttpServletRequest
aResponse - HttpServletResponse
Throws:
javax.servlet.ServletException

getHTMLErrorMessage

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

Parameters:
t - Throwable
