How to set a form bean property of type HashMap in jsp

[Vaneet Sharma <va...@crisil.com>]

Can anybody tell me how to set a form bean property of type 
java.util.HashMap in a jsp page.
Actually i am prepolulating this property in action and then forwarding to 
a jsp page.
In this jsp page i need to again set this property ,so tht if there is 
some validation error then this HashMap is not lost.
So tht is why i want to set this property of type HashMap in jsp page .

If all you need to do is to copy the property you  can use  <bean:define>

If your hashmap is being set as a request attribute

<bean:define name="mapAttributeName" id="copiedMap" scope="request"/>

If its a property of the form bean then,

<bean:define name="formBean" property="mapProperty" id="copiedMap"
scope="request"/>
