Intro
Similar to ASP, which uses C#, JSP is the one with uses Java behind. To deploy those applications we need a servlet container, like Apache Tomcat or JBoss EAP – Undertow. JSP dynamic web content, as XML. Together.
Deploy
We need a servlet container so in this case, we can use Jetty for the demonstration. Eclipse Jetty is a Java HTTP (Web) server and Java Servlet container, I will talk more about it on another post.
JSP Custom TAG
One of the most interesting features in my opinion about JSP, which is a nice feature btw, is the possibility to create custom tags HTML based on the HTML rules – ofc. Just follow the template below with the attributes you need.
TEMPLATE FOR HTML 4
<?xml version=”1.0″ encoding=”UTF-8″ ?>

Jsp will validate the HTML version on the begin of the page. Please use plain simple JavaScript in case you need validation.
