How to perform manipulation on form-bean variables??

[Pras Tiwari]

HI,

Following is some code in my JSP file in my struts application:-
============================
<tr>
<td>UNITS</td><td>UNIT PRICE</td><td>SUB TOTAL</td>
</tr>
<tr>
<td><bean:write id="cartbean" property="units"></td>
<td><bean:write id="cartbean" property="unit_price"></td>
<td> ??? /td>
</tr>
============================
Now in my above application code I am successfuly retrieving values of "units" &

"unit_price" fields from my form-bean. But now I want to display multiplication of "units" &

"unit_price"into "SUB TOTAL" column. How should I do this in my JSP?

What code should I write so that I can multiply these two fields & display values in third

column???

PLease help me.

Thanx in advance...

I'd suggest you add a method to your ActionForm bean to do this. For example:

public String getTotalPrice() {
   BigDecimal total = new BigDecimal(units * unit_price).setScale(2, BigDecimal.ROUND_HALF_UP);
   return total.toString();
}

You can then simply put <bean:write id="cartbean" property="totalPrice"> in your JSP.
