Observations :
a) The value of the res variable is null, hence calling the setCookie method
is throwing an exception and hence no cookie is being set.
b) The reason you are successfully able to use the getProperty method in the
other Jsp is because your abean variable has a session scope. If you change
the scope to page, the result would be different.
Hope this helps.
Have a nice day.
With regards,
Sachin S. Khanna.
