Manage HTTP headers with Java Servlets: Quick Notes
2008-10-15 13:43:00 In Java Servlets API, both HttpServletRequest and HttpServletResponse interfaces (in javax.servlet.http package) provide methods to programatically manipulate HTTP headers. There are a number of standard HTTP headers exchanged between a web server and a client (eg: a browser). "Content-Type" is a commonly used header (which is used to specify MIME type) in Servlets. In this article we are discussing how headers are read/written with Servlet classes.Reading HeadersA servlet can read HTTP headers sent by a client request using HttpServletRequest interface. This interface has two methods for this.String getHeader(String headerName)int getintHeader(String headerName)Both these methods are similar except getIntHeader() method is used to return value of headers with int type values. Below code shows how value of "User-Agent" header is read from the user request. (HttpServlet.doGet() method is used in the example).import javax.servlet.http.*;import java.io.*;public class MyServlet extends ...

Session Tracking In Servlets
2007-04-17 21:28:00 As HTTP is a stateless protocol, any interaction between client browser and servlet lasts as long as the browser is connected to server and the moment browser is closed this session is lost,in no way server will know anything about its client,if client access this server again.In applications where keeping a track of end user is must like in an online shopping or online banking applications,keeping a track of session between user and server is a must.In servlets, various mechanisms are suggested for maintaining session between both entities.One of them is through cookies.Cookies are server sent,small bits of text files which are stored in client browser and this is dependent upon whether client browser supports cookies or not.By default these cookies are deleted the moment client-server communication ends but they can persist for a specified period of time by a developer.When the browser access the same site again then already stored cookie in browser is exchanged with server.Here i...
What is the difference between Java Servlets and Java ServerPages (JSP)?
2007-04-17 21:22:00 A JSP is a Servlet with a Web page flavor.There are more similarities than differences between the two.JSP uses its own tags which are ultimately using tag libraries implemented in Java.The source code of a servlet with HTML embedded in out. print (...) statements, gives dynamic features to webpages but that makes a cumbersome process to maintain servelts from web design perspective.If someone has implemented GUI related code inside servlet then each time a small GUI change will result in recompilation of the whole code.Hence business logic centric development should be done inside servlet and JSP gives a choice of combining both in much targeted way.JSP was devised to differentiate the tasks of web designers,responsible for look and feel of the webpages, from web developers who deal in business logic development.So both entities have focused interest met through JSP.In fact, a JSP gets compiled into a servlet.
