JSP (Java server pages) and servlet basics

This states the requirements for the course which is a tomcat server along with JDK and Eclipse IDE.

This course configures the tomcat server with the Eclipse IDE so that we are finally ready to start coding.

This is a basic program which helps to print hello servlets using the Java servlets. In order to do so, we first have to add the JAR file.

This is a basic tutorial of the Servlet.

In this tutorial, we form a basic HTML page and JSP page. In an HTML page, we can apply JSP. Also in a JSP page, we can make use of HTML elements.

This describes the basic servlets cycle. This starts with loading a servlet class to providing service.

The declarations and expressions statements are described here. In JSP declarations are single line statements for variables for ex. to declare a variable, or called a date function etc. The expression is just like the print statement in Java.

The scripts can be said as combinations of the above two elements which is the expressions and the declarations which can span multiple lines. This lines can span through multiple lines, unlike the above two lines. Thus the loops, declarations etc. can be declared here.

The servlets declarations are mostly used for declaring functions. That is the main difference in the servlets and the scripts that we cannot declare functions in the scriptlets. And also the variables in the scriptlets need to be final.

This tutorial shows that how the HTML and Java comment is not so efficient in JSP and hence we need to use the JSP comments.

The JSP directives give us info about the metadata that is the information about the data present on the page. More on the topic will be seen ahead in the course.

Deployment Descriptor of a file is an artifact that is deployed to some container /engine. This describes how a module should be deployed based on the web annotation number. Here there are a couple of ways shown to change the URL by the web.xml which is the Deployment Descriptor which forms the way the things are arranged on the site.

The same (configuration of deployment descriptor) is shown in a series of steps here.

The following tutorial consists of reading the parameters in the search tab of the browser. Here the same is shown in JSP and also servlets. Hence their uses will be studied further.

In this tutorial, we will study the ways to add a file (local) so that it could be displayed on the web. Here given are the two ways which are unique in their ways which are for the type of the content they deal with. The directive method is for static content and the JSP include is for dynamic content.

In this, we can add packages such as the above-mentioned Date from Java .util.

The primary difference between the above two is that import can be done of a specific feature of some file. Thus while adding we cannot we the 'features' of the files as in import.

The major difference between forward and redirect is that request and response parameters are sent in forward command as contrary to the redirect one. In forward the Url remains intact. Forward requests to another resource within the same server.

In this following tutorial, the model view and control patterns are described. The basic use and advantages of using them along with an example give us their usability.

This is an exercise tutorial. This shows basic redirection in pages while clicking a particular link. Users can try to implement it while performing a task.

This is the solution to the above-stated example that deals with the creation of redirection of pages. This deals with many first time functions such as the request dispatcher, and also the interface of Servlet Context which has many functions which are used to communicate with servlet container, ex. write to a log file, request dispatcher etc.
