The Java Servlet is like every other Java class. You can compile it using the javac command or if you are using a Integrated Development Environment (IDE) like Eclipse, it will compile the class for you.
One main difference w.r.t Servlets is the fact that, they get deployed into EAR files (Enterprise Archive Files) and not JAR files (Java Archive Files) like normal java apps.
Servlets are like other/normal Java classes. they can be compiled using the javac command.
Tomcat is a server. It is used to deploy and run Servlets and not compile them. A Servlet is a java file and has to be compiled just like any other Java Class.
Java Servlet is used for Server Side programming for developing Web Applications. It easily employs Database Connectivity. We can also use JSP however it cannot replace a Java Servlet.
Java Applet is an application designed to transmit on internet to execute on java compatible browsers. Java Servlet is a server side program used to provide services to clients.
Networking is a basic action. A servlet in Java is a single part of networking, a single task.
One can run and compile a Java applet program by agreeing to the terms and downloading it. It is possible to get a compiler online that will compile and run Java programs.
You compile it.You compile it.You compile it.You compile it.
Yes you can but it is not required. A Servlet is nothing but another .java file and all rules that are applicable to standard Java classes are applicable to them. Note: Even if you write a constructor in a servlet, it will not get executed.
No. Javascript code can be present inside a JSP but not inside a servlet. A Servlet is a pure java class.
Servlet is more faster than JSP, but JSP is more convenient than Servlet and JSP is clearly superior, shorter, simple and easier to use. JSP can be perceived as Java in HTML code. JSP require no explicit compilation as like servlets and can keep in the web application server as HTML file. The web application server in turn compile the java code in JSP and load it in its library for future execution. Servlet can be perceived as HTML in Java code. The servlet is the class file, which would be loaded in the web application server as a program. The program output will be directed to the outstream object which in turn direct to the client as HTML elements.
Advance java is the implementation of servlet in web pages.
You cannot. HTML is a static file and it cannot interact with a Java Servlet. A Servlet can always redirect to a HTML page but the other way round cannot happen.
Java Servlet Development Kit is an integrated development kit used to build, test, and deploy Java Servlet applications. JSDK allows most standard Web server such as Netscape servers, IIS, Apache and others to load servlets . JSDK is a suite of software for easing the development of Java servlets.
