Hi,

I have developed an application using RADS. When i searched for the particular report, it takes pretty much time to load the data from database.
Reviewed the query and found tht it is optimized. Also done jsp precompilation option in RADS.
But still it takes longer time to load the screen. Below is the output in milliseconds. Can anyone guide me on this.

For fist time:

time for Query :: 24391 ms
time for coming out of DAO:: 17968 ms
time for coming out of Servlet :: 23968 ms

For second time
time for Query :: 4391 ms
time for coming out of DAO:: 7968 ms
time for coming out of Servlet :: 7968 ms

Please let me know if am missing something. Thanks in advance.

Hi,

Am creating a small application where i am using dispatch action class for Login as well as Change Password button. The login form has two input fields viz Username and Password and both fields cannot be empty.

It is working fine when we click on Login button.

But when we are not entering any inputs and wants to change password, it is not working until and unless i entered some values in two fields.

Please help how to change password for the above case without entering any fields values.

Thanks in advance.
