Problem with logic:iterate tag

[Mohammad Akon]

Hi, I am trying out an example. The codes & configurations are ----->

strusts-config.xml

        <action path="/EditProduct"
                type="com.admin.EditProductAction"
                name="productForm"
                scope="request"
                input="/editproduct.jsp"
                validate="true" >
            <set-property property="loginRequired" value="true"/>
            <forward name="success" path="/SearchProduct.do"/>
            <forward name="error" path="/editproduct.jsp"/>
        </action>
...........
...........
<action path="/SearchProduct" 
                type="com.admin.SearchProductAction" 
                scope="request" > 
            <set-property property="loginRequired" value="true"/>
            <forward name="success" path="/viewproduct.jsp"/>
            <forward name="error" path="/searchorder.jsp"/>
        </action>
...........
...........
<action path="/UpdateProduct" 
                type="com.admin.GetProductAction" 
                name="productForm" 
                scope="request" 
                validate="false" >
            <set-property property="loginRequired" value="true"/>
            <forward name="success" path="/editproduct.jsp"/>
            <forward name="error" path="/viewproduct.jsp"/>
        </action>
............
............

fragment of editproduct.jsp :- It allows the user to edit a product in the database.

I don't see logic:iterate in the editproduct.jsp. I see the close tag. And I see an open/close form tag. The open tag for logic:iterate needs to be nested somewhere in the form.
