These byte codes are essentially instructions encapsulated in single type, to what is known as java virtual machine JVM which resides instandard browser. JVM verifies these byte codes when downloaded by the browser for integrity. Java Virtual Machines available for almost all Operating Systems.
JVM converts these byte codes into machine specific instructions at runtime. Java is portable architecture neutral that is java programs once compiled can be executed on any machine that is enabled. Java is distributed in its approach and used for internet programming. Java is robust, secured, high performing and dynamic in nature. Java supports multithreading. There for different parts of the program can be executed at the same time 6.
Internet users can use java to create applet programs and run them locally using java enabled browser search as hot java. Applets can be downloaded from remote machine via internet and run it on local machine.
This system contains web pages that provide both information and controls. We can navigate to a new web page in any direction. This is made possible worth HTML java was meant to be used in distributed environment such as internet. So java could be easily incorporated into the web system and is capable of supporting animation graphics , games and other special effect.
The web has become more dynamic and interactive with support of java. We can run a java program on remote machine over internet with the support of web. Java architecture provides a portable , robust , high performing environment for development. Java provides portability by compiling the byte codes for the java virtual machine which are then interpreted on each platform by the runtime environment. Java also provides stringent compile and runtime checking and automatic memory management in order to ensure solid code.
The JVM will execute the byte code and overcomes the issue of portability. The code is written and compile for one machine and interpreted all other machines. This machine is called java virtual machine. The remaining features of a product can remain in the server. Changing economic model of the software Up-to-date software availability Supports network entire computing. We can build web pages or web document s. The browser reading the document interprets mark up tags to help format the document for subsequent display to a reader.
HTML is a language for describing structured documents. HTML is a platform independent. The browser interprets HTML tags in the web document and displays it. Different browsers show data differently. Examples of browsers used to be web pages include: Netscape Java scripts dynamically typed that is programs do not declare variable types, and the type of variable is unrestricted and can change at runtime.
Typical implementations compile by translating source into a specified byte code format, to check syntax and source consistency. Note that the availability to generate and interpret programs at runtime implies the presence of a compiler at runtime.
Java script is a high level scripting language that does not depend on or expose particular machine representations or operating system services.
It provides automatic storage management, typically using a garbage collector. Java script is embedded into HTML documents and is executed with in them. Java script is browser dependent Java script is an interpreted language that can be interpreted by browser at run time. Java script is loosely typed language Java script is an object based language. Java script is an Event-Driven language and supports event handlers to specify the functionality of a button.
Java script can be used for client side application 2. Java script provides means to contain multi frame windows for presentation of the web.
Java script provides basic data validation before it is sent to the server. It creates interactive forms and client side lookup tables. Servlets are to the server-side what applets are to the client-side -object byte codes that can be dynamically loaded off the net. They differ from applets in that they are faceless objects without graphics or a GUI component.
They serve as platform-independent, dynamically-loadable, pluggable helper byte code objects on the server side that can be used to dynamically extend server-side functionality. Unlike applets, however, servlets have no graphical user interface. They provide a way to generate dynamic documents that is both easier to write and faster to run.
Servlets also address the problem of doing server-side programming with platform-specific APIs: A servlet like this could be part of an order-entry and processing system, working with product and inventory databases, and perhaps an on-line payment system. Other Uses for Servlets Here are a few more of the many applications for servlets:. Allowing collaboration between people. A servlet can handle multiple requests concurrently, and can synchronize requests.
This allows servlets to support systems such as on-line conferencing. Forwarding requests. Servlets can forward requests to other servers and servlets. Thus servlets can be used to balance load among several servers that mirror the same content, and to partition a single logical service over several servers, according to task type or organizational boundaries. Architecture of the Servlet Package The javax. The architecture of the package is described below.
The Servlet interface declares, but does not implement, methods that manage the servlet and its communications with clients.
Servlet writers provide some or all of these methods when developing a servlet. Client Interaction When a servlet accepts a call from a client, it receives two objects:. Information such as the names of the parameters passed in by the client, the protocol scheme being used by the client, and the names of the remote host that made the request and the server that received it. Allows the servlet to set the content length and MIME type of the reply.
HTTP servlets have some additional objects that provide session-tracking capabilities. The servlet writer can use these APIs to maintain state between the servlet and the client that persists across multiple connections during some time period. HTTP servlets also have objects that provide cookies. The servlet writer uses the cookie API to save data with the client and to retrieve this data.
The classes mentioned in the Architecture of the Servlet Package section are shown in the example in bold:. Initialization completes before client requests are handled and before the servlet is destroyed. Even though most servlets are run in multi-threaded servers, servlets have no concurrency issues during servlet initialization. The server calls the init method once, when the server loads the servlet, and will not call the init method again unless the server is reloading the servlet. The init method provided by the httpservlet class initializes the servlet and logs the initialization.
To do initialization specific to your servlet, override the init method following these rules:. If an initialization error occurs that renders the servlet incapable of handling client requests, throw an Unavailable exception. This method takes the parameter name as an argument and returns a String representation of the parameter's value. The specification of initialization parameters is server-specific.
In the Java Web Server, the parameters are specified with a servlet is added then configured in the Administration Tool. For an explanation of the Administration screen where this setup is performed, see the Administration Tool: Adding Servlets online help document.
If, for some reason, you need to get the parameter names, use the getparameternames method. When a server destroys a servlet, the server runs the servlet's destroy method. The method is run once; the server will not run that servlet again until after the server reloads and reinitializes the servlet.
When the destroy method runs, another thread might be running a service request. The Handling Service Threads at Servlet Termination section shows you how to provide a clean shutdown when there could be long-running threads still running servicerequests. Using the Destroy Method The destroy method provided by the httpservlet class destroys the servlet and logs the destruction.
To destroy any resources specific to your servlet, override the destroy method. The destroy method should undo any initialization work and synchronize persistent state with the current in-memory state. The following example shows the destroy method that accompanies the init method shown previously: A server calls the destroy method after all service calls have been completed, or a server-specific number of seconds have passed, whichever comes first.
If your servlet handles any long-running operations, service methods might still be running when the server calls the destroy method. You are responsible for making sure those threads complete. The next section shows you how. The destroy method shown above expects all client interactions to be completed when the destroy method is called, because the servlet has no long-running operations.
The server tries to ensure this by calling the destroy method only after all service requests have returned, or after a server-specific grace period, whichever comes first. If your servlet has operations that take a long time to run that is, operations You must make sure that any threads still handling client requests complete; the remainder of this section describes a technique for doing this. If your servlet has potentially long-running service requests, use the following techniques to: Keep track of how many threads are currently running the service method.
Provide a clean shutdown by having the destroy method notify long-running threads of the shutdown and wait for them to complete. Have the long-running methods poll periodically to check for shutdown and, if necessary, stop working, clean up and return. Tracking Service Requests To track service requests, include a field in your servlet class that counts the number of service methods that are running.
The field should have access methods to increment, decrement, and return its value. The service method should increment the service counter each time the method is entered and decrement the counter each time the method returns. This is one of the few times that your httpservlet subclass should override the service method. The new method should call super. Providing a Clean Shutdown To provide a clean shutdown, your destroy method should not destroy any shared resources until all the service requests have completed.
One part of doing this is to check the service counter. Another part is to notify the long-running methods that it is time to shut down. For this, another field is required along with the usual access methods. Creating Polite Long-running Methods. The final step in providing a clean shutdown is to make any long-running methods behave politely. Methods that might run for a long time should check the value of the field that notifies them of shutdowns,and interrupt their work if necessary.
The service method supports standard HTTP client requests by dispatching each request to a method designed to handle that request. For example, the service method calls the do Get method shown earlier in the simple example servlet. Requests and Responses: You must parse this data yourself to obtain the parameters and values. They can not be used together in a single request.
Closing the Writer. This header is often the only one manually set. Your servlet should override the method or methods designed to handle the HTTP interactions that it supports. This section shows you how to implement methods that handle the most common HTTP requests: The default implementation of do Options automatically determines what HTTP options are supported and returns that information.
These methods are not typically overridden. The servlet description is a string that can describe the purpose of the servlet, its author, its version number, or whatever the servlet author deems important. You are not required to override this method, but applications are unable to supply a description of your servlet unless you do. Writing Your First Servlet Servlets are also easy to develop.
This document discusses the following minimum steps needed to create any servlet: Write the servlet Save the file with a. Test the servlet Invoke the servlet from a JDK1.
Its general implementation serves as a basis for more sophisticated state models, such as persistent user profiles or multi-user sessions. A session is a series of requests from the same user that occur during a time period. This transaction model for sessions has many benefits over the single-hit model.
It can maintain state and user identity across multiple page requests. It can also construct a complex overview of user behavior that goes beyond reporting of user hits. Server-Side Session Objects and Users Session tracking gives servlets and other server-side applications the ability to keep state information about a user as the user moves through the site.
Java Web Server maintains user state by creating a Session object for each user on the site. These Session objects are stored and maintained on the server.
When a The session ID matches the user with the Session object in subsequent requests. The Session object is then passed as part of the request to the servlets that handle the request. Servlets can add information to Session objects or read information from them. Session Endurance After the user has been idle for more than a certain period of time 30 minutes by default , the user's session becomes invalid, and the corresponding Session object is destroyed. A session is a set of requests originating from the same browser, going to the same server, bounded by a period of time.
Loosely speaking, a session corresponds to a single sitting of a single anonymous user anonymous because no explicit login or authentication is required to participate in session tracking. The second part of the method gets an integer data value from the Session object and increments it.
The third part outputs the page, including the current value of the counter. When run, this servlet should output the value of the counter that increments every time you reload the page. This guarantees that the session tracking headers are sent with the response. In this example, an Integer object is read from the Session object, incremented, then written back to the Session object.
Any name, such as sessiontest. When choosing names, remember that the Session object is shared among any servlets that the user might access. Servlets may access or overwrite each other's values from the Session. Thus, it is good practice to adopt a convention for organizing the namespace to avoid collisions between servlets, such as: Session Invalidation Sessions can be invalidated automatically or manually.
When a session is invalidated, the Session object and its contained data values are removed from the system. After invalidation, if the user attempts another request, the Session Tracker detects that the user's session was invalidated and creates a new Session object. However, data from the user's previous session will be lost. Session objects can be invalidated manually by calling session. This will cause the session to be invalidated immediately, removing it and its data values from the system.
The session ID is a string that is sent as a cookie to the browser when the user first accesses the server. On subsequent requests, the browser sends the session ID back as a cookie, and the server uses this cookie to find the session associated with that request.
There are situations, however, where cookies will not work. Some browsers, for example, do not support cookies. Other browsers allow the user to disable cookie support.
In such cases, the Session Tracker must resort to a second method, URL rewriting, to track the user's session. URL rewriting involves finding all links that will be written back to the browser, and rewriting them to include the session ID. For example, a link that looks like this: This is then used to obtain the proper Session object.
Implementing this requires some reworking by the servlet developer. Instead of writing URLs straight to the output stream, the servlet should run the URLs through a special method before sending them to the output stream. Determine URL Rewriting: Rules for URL rewriting are somewhat complex, but in general if the server detects that the browser supports cookies, then the URL is not rewritten.
The server tracks information indicating whether a particular user's browser supports cookies. Return URL modified or the same: Otherwise, the URL is returned unmodified. For example, a servlet that used to do this: Send redirect response. Encode redirecturl "http: MultipleServlets URL conversions are required only if the servlet supports session tracking for browsers that do not support cookies or browsers that reject cookies.
The consequences of not doing these conversions is that the user's session will be lost if the user's browser does not support cookies and the user clicks on an un-rewritten URL. Note that this can have consequences for other servlets. If one servlet does not follow these conventions, then a user's session could potentially be lost for all servlets. Page compilation also simplifies the task of supporting session tracking. To that end, if URL rewriting is Additional APIs In addition to the Session object, there are a few more classes that may interest the servlet developer.
Description httpsessioncontext Class The httpsessioncontext is the object that contains all existing and valid sessions.
The http session context can be obtained by calling get Session Context on the Session object. When the Session object is invalidated, its contained values are also removed from the system. Some of these values may be active objects that require cleanup operations when their session is invalidated.
If a value in a Session object implements HttpSessionBindingListener, then the value is notified when the Session is invalidated, thereby giving the object a chance to perform any necessary cleanup operations.
Session Swapping and Persistence An Internet site must be prepared to support many valid sessions. A large site, for example, might have hundreds, or even thousands, of simultaneously valid sessions. Because each session can contain arbitrary data objects placed there by the application servlets, the memory requirements for the entire system can grow prohibitively large. To alleviate some of these problems, the session tracking system places a limit on the number of Session objects that can exist in memory.
This limit is set in the session. When the number of simultaneous sessions exceeds this number, the Session Tracker swaps the least recently-used sessions out to files on disk.
Those sessions are not lost: This system allows for more sessions to remain valid than could exist in memory. Session invalidation is not affected by session swapping.
If a session goes unused for longer than the normal invalidation time, the session is invalidated, whether it is in memory or on disk. Session invalidation is set in the session. Sessions are written to and read from disk using Java serialization. For this reason, only serializable objects put into the Session object will be written to disk. Any objects put into the Session object that are not serializable will remain in memory, even if the rest of the Session object has been written to disk.
This does not affect session tracking, but does reduce the memory savings that the Session Tracker gets from swapping a session to disk. For this reason, the servlet developer should try to put only serializable objects into the Session object. Serializable objects are those that implement either java. Serializable or java. The session-swapping mechanism is also used to implement session persistence, if the session persistence feature is enabled.
When the server is shut down, sessions still in memory are written to the disk as specified in the session. When the server starts again, sessions that were written to disk will once again become valid. This allows the server to be restarted without losing existing sessions. Session persistence is intended for preserving sessions across server restarts.
It is not meant to be used as a general long-term session persistence mechanism.
Customizing Session Tracking Session-tracking interfaces are in the javax. Properties You can customize properties in the Session Tracker. The properties are kept in the server. These property settings are applied to all sessions, and cannot be tuned for individual sessions. Parameter Description 45 Default.
