Dear,

First u need to set the hyperlink of the action(in
which u have implemented delete method logic) on the
primary key basis through which u will delete the
record and create an action forard in struts config
file(action of the class in which u have implementated
the logic to diaplay records in the view) and forward
to that action from delete method.

---------------- Struits-config.xml ----------------
<forward name="viewAction"
type="viewAction.do?parameter=methodName">
-----------------------------------------------------

------------------- View ----------------------------
<a href="deleteAction.do?primaryKey=xyz"> Delete </a>
(or use struts link tag)
-----------------------------------------------------

from delete action u need to forward to viewAction and
all display logic will be there.

Plz let me know in case of any inconvenience/problem.

regards,
Buland
