I am not sure, what you want to show on jsp2
but let me try..

you said you want to submit some DATA from PAGE 1
then retrieve some info from database and show that data
in PAGE 2

But the mapping you shown is not correct for that
follow these steps

1. Create a mapping for action1 which does not take any
ActionForm.

2. Forward the request from that action1 to some jsp1
which will take the input from user(i.e. searchType,age ...)

3. Create a mapping for action2 which takes a  DynaValidatorForm
for all the user data u received in jsp1

4. Extract the info from database using data received
in DynaValidatorForm

5. Set the data in session or request scope in the form of a Bean

6. Forward the request to jsp2

7. In jsp2 show the data using <html:bean> tag or in the form
of html form if you want to again send that data to some third
action.
