Constant Field Values

singleton_editor

protected static XHTMLFormEditor singleton_editor

Singleton XHTMLFormEditor reference. There's no reason to have more than one XHTMLFormEditor instance kicking around, or to incur the setup overhead more than once. So we maintain a single reference for use.

Constructor Detail

XHTMLUIEditorServlet

public XHTMLUIEditorServlet()

Method Detail

doGet

public void doGet(javax.servlet.http.HttpServletRequest req,
                  javax.servlet.http.HttpServletResponse res)

Pass HTTP 'GET' request over to handleRequest method.

Overrides:

doGet in class javax.servlet.http.HttpServlet

doPost

public void doPost(javax.servlet.http.HttpServletRequest req,
                   javax.servlet.http.HttpServletResponse res)

Pass HTTP 'POST' request over to handleRequest method.

Overrides:

doPost in class javax.servlet.http.HttpServlet

handleRequest

protected void handleRequest(javax.servlet.http.HttpServletRequest req,
                             javax.servlet.http.HttpServletResponse res)

Use our XHTMLFormEditor to process the request.

failout

protected void failout(java.lang.String text,
                       javax.servlet.http.HttpServletResponse res)

Die with the appropriate message

getXHTMLFormEditor

protected XHTMLFormEditor getXHTMLFormEditor(javax.servlet.http.HttpServletRequest req,
                                             javax.servlet.http.HttpServletResponse res)

Initializing accessor for the XHTMLFormEditor we use. Once the instance is set up, we just return it without any synchronization overhead.

createFormEditor

protected void createFormEditor(javax.servlet.http.HttpServletRequest req,
                                javax.servlet.http.HttpServletResponse res)

This method initializes our XHTMLFormEditor instance. This method is synchronized so that two separate servlet instances won't both try to initialize the common reference at the same time. We test that our reference is null, so subsequent calls to this method after things are set up are harmless.
