Dear all,
We have a application built using Struts.
Below is the architecture in brief :
JSP à Action Class à
Business Delegate à
Session Façade à
Database
We are not using Action forms. We are using
Value Objects (VO) to pass data between web tier and App tier (from action to
EJB via Business Delegate).
Problem:
We have a very big form with many input
fields/select fields.
There are two scenarios
- Insert
the record
This seems fine. We take all the data entered by user on the screen in
action class, create VO and pass it to EJB which inserts into database.
- Update
the record
Here we
have a Problem.
Screen is populated with data retrieved from database. Here user can
update few/all fields. All the fields are under one form. User clicks on
save button. Only one Save button is available on page which submits the
complete page. The problem is that even if user does not update/add any
value and clicks on save button, all the field values (unchanged and
changed, both) will pass till EJB and the whole record in database will get
updated but in reality update require only for changed fields.
Screen is bit complex with all types of input fields with ADD MORE and DELETE
ROWS kind of functionality also. Screen can not have more than one SAVE
button.
Please let us know what to use to solve such kind of performance issues.
Thanks & Regards,
Viral
