Hi Kri,
Narrowing (explicit cast) means you want to shove something big into something small (float --> int) and you need to let the compiler know that your aware that there could be a "possible loss of precision". Widening (implicit cast) doesn't require you to write the cast, the conversion will happen automatically beacuse the compiler knows a byte value will fit inside an int .

Also spend some time learning about access modifiers (public, private, protected, default).

Hi Maen,

check out Programmer Certification Study FAQ. There is lots of useful stuff there.
If your using the Bean tags or HTML tags in your iteration set the filter attribute to true. Check out web page
for more information.

In my project i have one jsp page with 5 buttons and each button has different functionality based on button click i want to call respective Action form and in my action class (only one) i want to check which button is clicked.
please tell me do we have any tag in struts for pagination.

hi bhumika ,
In most cases there are several benefits to a single ActionForm (manageability, relationship preservation, etc...). It sounds like you just want to perform a defined operation in your Action class based on which button is selected, if this is the case check out the DispatchAction or DispatchLookup Action if you don't want to use JavaScript buttons. Let me know if you need more info.

The pasted code is not setting any of the parameters...
proc.setString(1, beanName.getSomeValue()); should have 200 of these.

I agree, the form name in validation.xml should be the same as the action name in the configurations file.

are any of the form elements validating?

use the onClick attribute to submit the form.

on reset you can drop the bean reference from the session or have a clearValues method in your bean that will clear all bean values.

This type of thing should only be done by a DBA. Oracle can and should manage this process on its own.

your logic tag is fine. Could you post declare, setter and getter for blnRecsFound. What is the bean scope in JSP?
