I am getting exception.

No getter method available for property name for bean under name products

<html:select property="productName">
<html

ptions name="products" property="name" />
</html:select>

"products" is the Set in the session and name is the property to display in the options.

You'll need your code to look like this then

where myFormBean is the name of your struts form bean. Also notice the attribute collection instead of name. Give that a try

Now I am having one more problem, if the Set is empty in the jsp I am getting empty select box. If the Set is empty I need to show as "No values".

How can I do this.

Thanks.

I'd suggest taking care of this in the Action class. Get the list of products from the database, check to see if the list is empty, and if so add the element "No Values" to the list prior to forwarding to the JSP.
