 What impact a JavaBeans object can produce when it is stored in Servlet Request object?

 

 

 JavaBean object that is stored in Servelet Request object remain accessible for the duration of current request. In other words until you continue to forward request to another servlet/JSP the bean value would be available    

 

Question No: 34    ( Marks: 2 )

After a thread is started, via its start() method or that of the Thread class, the JVM invokes the thread's run() method when the thread is initially executed.

 What is the significance of error page?

 

We can configure error pages in jsp and servlets to direct the control to a custom error page, showing a friendly error message to the user when an exception is thrown in the page. Error pages enable you to customize error pages. You can even hide them from the user's view entirely, if you want. This also makes possible to maintain a consistent look and feel throughout an application, even when those dreaded error messages are thrown. An Error JSP is called by the web server when an uncaught exception gets occurred.

Some custom, server-specific URL change

 

 

Question No: 37    ( Marks: 3 )

 Differentiate between Sequential Execution and multithreading.

Every program has atleast one thread. Programs without multithreading executes sequentially. That is, after executing one instruction the next instruction in sequence is executed. If a function is called then until the completion of function the next instruction is not executed. Similarly if there is a loop then instructions after loop get only executed when loop is completed.

Multithreading allows two parts of the same program to run concurrently A problem with single-threaded applications is that lengthy activities must complete before other activities can begin. In a multithreaded application, threads can be distributed across multiple processors (if they are available) so that multiple tasks are performed concurrently and the application can operate more efficiently. Multithreading can also increase performance on single-processor systems that simulate concurrency—when one thread cannot proceed, another can use the processor.

 

 

 

 

 

 

 

 

  

Question No: 38    ( Marks: 5 )

 Which technology is used in JAVA to support following layers?

Question No: 39    ( Marks: 5 )

 How cookies are sent to a client?

   Create a Cookie Object

Cookie c = new Cookie (“name”, “value”);

 

 

Setting Cookie Attributes

c.setMaxAge(60);

 

 

Place the Cookie into HTTP response

Response.addCookie(c);

 

Question No: 40    ( Marks: 10 )

 What are the characteristics of web services?

Interoperable

Economical

Automatic

Accessible

Available

Scalable

 

Question No: 41    ( Marks: 10 )

 What is the usage of sleep (int time) method?

Sleep method will Causes the currently executing thread to wait for the time (milliseconds) specified

Waiting is efficient equivalent to non-busy. The waiting thread will not occupy the processor.

Threads come out of the sleep when the specified time interval expires or when interrupted by some other thread

Thread coming out of sleep may go to the running or ready state depending upon the availability of the processor.

High priority threads should execute sleep method after some time to give low priority threads chance to run otherwise starvation may occur

Sleep can be used for delay purpose i.e. anyone cal call Thread.sleep()method
