Hello there,

I want a method (or some functionality) to be executed after my web application starts (context loaded). I am using spring 3.0 as framework.

I tried using ServletContextListener which I implemented in my class


my listener class

package myapp.listner; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; public class MyContextListner implements ServletContextListener{ public static long appStart=0L; @Override public void contextDestroyed(ServletContextEvent arg0) { System.out.println("Context Destroyed"); } @Override public void contextInitialized(ServletContextEvent arg0) { appStart=System.currentTimeMillis(); System.out.println("Context Initialised"); } }


and part of web.xml is

<listner> <listner-class>myapp.listner.MyContextListner</listner-class> </listner> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/forms/*</url-pattern> </servlet-mapping>


but its not printing that message.....

I need to convert a decimal number to IEEE 754 half , single, Double precision numbers

I did it for single precision Please help me for half and double precision

code for single what I did is as follows
String globalAnswer=""; ///where answer is stored Float myDec = Float.parseFloat(givenDecimal);//given decimal int intBits = Float.floatToIntBits(Math.abs(myDec)); int sign = intBits & 0x80000000; //intBits = Float.floatToIntBits(Math.abs(myDec)); System.out.println("intbits" + intBits); int exponent = intBits & 0x7f800000; int mantissa = intBits & 0x007fffff; if (myDec > 0) { globalAnswer = Integer.toBinaryString(sign) + Integer.toBinaryString(exponent).substring(0, 9) + Integer.toBinaryString(mantissa); } else { globalAnswer = "1" + Integer.toBinaryString(exponent).substring(0, 9) + Integer.toBinaryString(mantissa); }

Thanks to all!

Hello,

I have one question in mind!

Does only JSP servlets project without any framework run properly?

I mean if multiple users (lets assume 100 users) use it simultaneously, will it work properly?

I am just using JSP servlets and JDBC but declaring all variables local in JSP and Servlets too.

Hello,

I am working on one project where I have used JSP and Servlets only. No framework is used.

Now project is about to end if I want to integrate it with spring framework is it possible?

If possible how?

I have used more JSP pages for controlling and very less servlets hardly 3-4.

Hello,

I need to evaluate the expression. Please help me!

Example:

equation is:
a = b + c * d + e / f
I need to print on console

x= c * d
y = e / f
z = b + x
w = z + y
a= w

I separated the expression by splitting string
but after i am confused what to do!

Please help me.

Thanks to all!

I need low level information about execution of program. suppose how many logical gates are used while executing a code?


How can I get it?

Are there any APIs which provides such classes or information?

What is it?

Absolutely right!

Please tell me that

Does servlet have controller?
It really needs it?

If not how it loaded in memory?

if yes then what is purpose of init() method?
