You are calling method getPin() while your bean defines a getpin() method (note the difference in "P" and "p").
Change method declarations or adjust the JSP code, you should be fine then.

hi,
Thanks for the help but still i am not able to find the difference in the method getpin().It looks as if everything is proper, if at all there is a difference then could you help me out with that particular line of code so that i can make the changes.
Thanks in advance.I am waiting for your reply

You are not following the Java Bean spec. A property called 'pin' or 'acc' needs to have getters/setters in the form 'getPin', 'setPin'. You take the property name ('pin'), capitalize the first letter ('Pin') and place the get/set infront of it ('getPin'). The tags jsp:setProperty and jsp:getProperty are attempting to use the Bean Spec to access your getters/setters which are named incorrectly. If you look closely, that is whata the error message is telling you.

You need to correct the getters/setters for both acc and pin.
