what is the difference between application server and web server?
459102
Application server is a Web server with the notion of logic. In other words, you can host applications there and expose those applications through a Web-based product. Web servers just service up content, HTML pages and other Web-capable files.

Apache is a webserver, listen by default on http port 80, and Tomcat is a servlet engine, which can be integrated with apache to listen on 80 port and the webservers are very helpful in big applications \n1) to handle / share load the request from the clients, ( by filtering the static content requests)\n2) to implement the application security by isolating the application server (here it is tomcat) from the webserver.\n\nWebservers are more advantageous in a geographically distrubuted web application.

Application server :- jboss,weblogic,websphere etc.These servvers implements J2EE standards  Webserver :- Apache webserver.Generally holds static html,images etc.\ndead lock occures in Threads

ASP is short for Automatic Server Page.\n\nActive Server Pages (ASP) is Microsoft's server-side technology for dynamically-generated web pages that is marketed as an add-on to Internet Information Services (IIS).\n\nProgramming ASP websites is made easier by various built-in objects. Each object corresponds to a group of frequently-used functionality useful for creating dynamic web pages. In ASP 3.0 there are six such built-in objects: Application, ASPError, Request, Response, Server and Session. Session, for example, is a cookie-based session object that maintains variables from page to page. Application Center Test is also available for load testing.\n\nMost ASP pages are written in VBScript, but any other Active Scripting engine can be selected instead by using the @Language directive. JScript (Microsoft's implementation of ECMAScript) is the other language that is usually available. PerlScript (Perl) and others are available as third-party installable Active Scripting engines.

web server is a computer with ISA server  or apache ,.... on it.you can put your website (for example html files) on it and make a virtual directory and refer it to there.then people on that network can go to your web page : http://computername/default.html\napplication server is a place to put your other data that network users connect to them and use those data in their programs\ngo to your browser or run : &#92;&#92;computername

plain and simply put, a server is the computer which directs network traffic (ie. permits or denies), it provides services to clients (ie. print, DHCP, DNS, File Sharing, Storage, and many more). A client is ANY machine that utilizes said services from a Server, being this is true, at times if a server is using services from another server, then the one server is in effect a client.

active server pages.net is really composed of two parts - microsoft's active server pages technology and microsoft's .net framework technology.   aspx.net uses a code behind file to perform server behaviors. it helps you create web pages that can post information to a server, or get information from a server, like registration forms, logins, etc.

Web services are a way of providing remote methods for applications, websites etc. They are generally consumed by running either a post or get and data is transmitted through the soap protocol, generally as an xml feed.\n\nFor example you may have a simple webservice method which retrieves an individual record by passing an id.\n\nThese services can be exceedingly useful when combined with ajax (asynchronous javascript and xml) as the page doesnt need to be refreshed to show changes in data.

As and example, instead of having to write every function you might need you can call functions using the interface provide by an  API. Assuming you can find an API that does what you want.\n\n\nAn application programming interface (API) is the interface that a computer system, library or application provides in order to allow requests for service to be made of it by other computer programs, and/or to allow data to be exchanged between them

The Java Servlet API allows a software developer to add dynamic content to a Web server using the Java platform. The generated content is commonly HTML, but may be other data such as XML. Servlets are the Java counterpart to dynamic web content technologies such as CGI, PHP or ASP. Servlets can maintain state across many server transactions by using HTTP cookies, session variables or URL rewriting.\n\nThe Servlet API, contained in the Java package hierarchy javax.servlet, defines the expected interactions of a web container and a servlet. A web container is essentially the component of a web server that interacts with the servlets. The web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access rights.\n\nA Servlet is an object that receives requests (ServletRequest) and generates a response (ServletResponse) based on the request. The API package javax.servlet.http defines HTTP subclasses of the generic servlet (HttpServlet) request (HttpServletRequest) and response (HttpServletResponse) as well as an (HttpSession) that tracks multiple requests and responses between the web server and a client. Servlets may be packaged in a WAR file as a Web application.\n\nMoreover, servlets can be generated automatically by JavaServer Pages (JSP), or alternately by template engines such as WebMacro. Often servlets are used in conjunction with JSPs in a pattern called "Model 2", which is a flavor of the model-view-controller pattern.

It depends on what you want to do, and what you want to share. \n\nFor users, I always recommend Windows, since there are many many applications that you can run.  But maintain your computer.  Remove unused programs and delete useless files.  Keep your SpyWare under control, and your Anti-virus software running and updated.   Configure your firewall as needed.  \n\nFor Web applications, I prefer a Linux server.   The software is much cheaper, and security is handled better.  I simply don't rent, or recommend Windows servers for web use.  (Although I am currently working on an ASP application).   \n\nOf course, I agree that Macs have the best PRINT graphic applications... PERIOD. \n\nGood luck

Well, if I were you I would save the web application that I am making in the root folder that is available in the Tomcat folder. On running the tomcat server the page will automatically be displayed. Try it out. Oh by the way, make a folder of yours inside this root folder and then type the following in the address bar:\nhttp://localhost:8080/folder\nPls note that the port can change. Also the folder name is not case sensitive. Take care and all the best!

Let me understand the question, you want to know what kind of work goes on, at the server side of a network, right ?\nA server is the main person in the network. Anything & everything that is being worked on in network, has to pass through a server. A Server helps to co-ordinate every task with the back end. Now every application has a front end & a back end. Front end is what is visible to the end user and back end is what stores all the data, all the files, and helps in bridging the systems. Server also provides security to the data by not allowing end users to modify it without the admin's consent. I hope this answers your question...\nhttp://www.microsoft.com/windowsserver2003/sbs/serverinfo/default.mspx

The main difference between a mainframe and a server is that a mainframe can run for years without a scratch, it's more secure, you can use any kind of software on it and much more. They are usually used inside huge companies because they cost a lot! The fact that some companies started prefering servers is only because they want to make more profit. I mean instead of buying 3 mainsframes they could buy 30 servers that could do the work for some time, and then if everything goes well they either change their mind and want to buy mainframes or servers again and again! I don't see any other reason!

phillip, if you don't know what you're talking about, don't talk.\nThere IS no difference.\nSee, a web server is USUALLY considered an HTTP or FTP server, ie. something most browsers can see.\nbut technically, any kind of proces which opens a certain port and listens to in on a machine is a server...A web server.\nWell, that given it's tunning on TCP/IP, otherwise it's another type of server...Like an Apple Sever, for example.
