30 Different Types of URL Patterns in Java Web Application | Adv Java Servlet Programming Tutorial

#Different #Types #of #URL #Patterns: #adv java #Advance #Java #Servlet #Programming #Tutorial - Creating URL Completely from scratch level by specifying hostname/ip address, port number, web root name etc... details is nothing but creating/framing "Absolute URL".

- Framing url by specifying the identification name of the resource is called as framing relative url.

- So avoid working with absolute urls in the web-resource programs of web application to make our web application as WODA(Write Once Deploy Anywhere) application, for this its recommended to use relative url's as like:

Ex: Absolute action URL (Not recommended)
-----------------------------------------
form action="http://localhost:2020/VoterApp/vturl" method="get"
------- Absoulute Action URL (not Good)
-------
-------
/form
or

pw.println("a href='http://localhost:2020/VoterApp/input.html' Home /a");
Absoulute Action URL (not Good)

Ex: Relative URL (recommended)
------------------------------
form action="vturl" method="get"
------- *1 -- Relative Action URL (Good/recomed to use)
-------
-------
/form
or

pw.println("a href='input.html' Home /a");
*2 -- Relative Action URL (Good/recomed to use)

Here href is called as hyer reference
Here https is called HTTP of Over SSL (SSL is used to send data over encrypted format)


Note - The modification done in .html, .xml etc file will be recoginzed by underlaying server automatically, without reloading , recompiling of the web application.

- But the modification done in .java file will not be recognized by server automatically.
(to recognize atuomaticaally .java file modification we need to recompile all servlet/java file & need to reload java web application --- compulsory)
