Hi All

I struts we can handle the exceptions using

1) validations: here we validate inputs and contron will be transfered to the input page of the action as per the validation rule voilation or we can simply validate the values in action class and send the contron on to desired page.

2) using declarative Exception Handling: in deployment descriptor we can declare on which type of exception request should be redirected to which page.

Waiting for comments.

hi

to handle the errors:

in struts project to handle the error objet by using ActionError object and to handle the errors by using ActionErrors object.

for suppose

ActionError ae1 new ActionError( err.one );

ActionError ae2 new ActionError( err.two );

Action Errors aes new ActionErrors();

aes.add(ae1);

aes.add(ae2);

saveErrors(request aes);//store the errors object in request object

to handle exception:

1)using try and cach blocks

2)using declarative exception handling technique

to handle the exceptions by using global exceptons tag in struts-config.xml

<global-exceptions>

<exception key gen.err type java.lang.ClassNotFoundException path /gen.jsp />

whenever that exception will be came it executes the gen.jsp page.
