Differniate between applet and servlet in java?
Applet: It is run on browser, i mean client side. Servlet: It is run on server, i mean server side.
What is the difference between an applet and a servlet?
Applet is a part of Core JAVA and Servlet of Advance Java. Applet is client side program and Servlet is Server side. When Applet runs it take the resources of client whereas Servlet is processed at server. An Applet's class, jar files can be accessed and downloadable by client but not so in case of servlet. Applets can run under any web browser their execution is dependent on Client as they require JRE Whereas Servlets do not require any thing specific at client side, as they require java enabled web/application Server. Dilpreet Singh (SCJP,OCA 9i) www.geocities.com/heartsinghThe main difference is that a servlet is a server side component while applet is a client side component, moreover, a servlet doesn't have GUI while applet have GUI. A servlet runs inside a server and results are sent to client, so it consumes less network bandwidth, and also secure, while applet runs on client side in a browser, so entire code for applet is 1st sent to client and then it is executed on the client machine itself, so it also consumes more network bandwidth.
Differentiate Java applet and 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.
What is servlet mapping?
A Servlet Mapping is a directive in the web.xml that tells the Servlet Container which class to use when a particular Servlet is called. A Servlet is a class within your Java Web Application. Let's say you have a servlet called MyServlet in the com.example.servlet package. You would need to have a Servlet Mapping pointing the path "/MyServlet" to the "com.example.servlet.MyServlet" class. Without the servlet mapping, you would not be able to invoke your servlet because the Servlet container would not know where it is. JSPs are different - they do not need mappings like this. JSPs exist within the WebRoot of the application, so they are always available. Servlets exist in the WEB-INF\Classes directory once your application is deployed.
What is an applet?
An applet is a small program module which runs under the control of a larger application, for example a web browser.

How easily does servlet integrate into an existing Java application or applet?
(This is a bit subjective). Servlets can integrate easily into an existing Java application or applet, simply because a servlet is just another class, which is a fundamental concept taught to almost every java programmer.
What are types of servlet?
Http servlet and Generic servlet
What is the DOS command applet?
There is nothing called DOS applet.. You can run Java applet from DOS..
When an applet become an applet?
Any Java class that extends java.applet.Applet is an applet. http://java.sun.com/j2se/1.5.0/docs/api/java/applet/Applet.html
What is java servlet chaining?
Servlet Chaining means the output of one servlet act as a input to another servlet. Servlet Aliasing allows us to invoke more than one servlet in sequence when the URL is opened with a common servlet alias. The output from first Servlet is sent as input to other Servlet and so on. The Output from the last Servlet is sent back to the browser. The entire process is called Servlet Chaining.
Why main function is not used in applet programs?
Because an applet runs in a browser, and in this context the one in charge of the launch and execution of the applet is the Java Plug-in software in the browser. This plugin controls the applet life cycle through methods in our applet. These methods are init, start, stop and destroy. In this case the methods that the plugin search to begin the execution of the applet are init (to initialize itself) and start (to start the execution of the task in the applet).
Is there a way to connect an IRC applet to QuakeNet?
QuakeNet has its own webchat applet named 'qwebirc'. Preferably using their own applet. Information about their applet can be found on their website. A direct link to incorporating a client hosted on their server follows, http://webchat.quakenet.org/. Incorporating their applet on your own server is possible too, by installing their applet's source code on your server. A direct link to the source code for the applet can be found at http://qwebirc.org/.
How does Apache httpd work?
Tomcat is a servlet container, and the following is how a servlet container works The init, service, and destroy methods are the servlet's lifecycle methods. The init method is called once by the servlet container after the servlet class has been instantiated to indicate to the servlet that it being placed into service. The init method must complete successfully before the servlet can receive any requests. A servlet programmer can override this method to write initialization code that needs to run only once, such as loading a database driver, initializing values, and so on. In other cases, this method is normally left blank. The service method is then called by the servlet container to allow the servlet to respond to a request. The servlet container passes a javax.servlet.ServletRequest object and a javax.servlet.ServletResponse object. The ServletRequest object contains the client's HTTP request information and the ServletResponse encapsulates the servlet's response. These two objects enable you to write custom code that determines how the servlet services the client request. The servlet container calls the destroy method before removing a servlet instance from service. This normally happens when the servlet container is shut down or when the servlet container needs some free memory. This method is called only after all threads within the servlet's service method have exited or after a timeout period has passed. After the servlet container calls destroy, it will not call the service method again on this servlet. The destroy method gives the servlet an opportunity to clean up any resources that are being held (for example, memory, file handles, and threads) and make sure that any persistent state is synchronized with the servlet's current state in memory.

How do you run applet program?
By Embedding it into a HTML page, create a new file with the extension .html (like app.html) insert following code: No Java 2 SDK, Standard Edition v 1.4.2 support for APPLET!! Adjust the code for your applet file (can't help there i am not a java programmer) or just use : No Java 2 SDK, Standard Edition v 1.4.2 support for APPLET!! but i recommend the first because the applet tag is deprecated and not supported in XHTML
