This bean has a map property named 'productMap'. This product map has the product code as the map's key and the product name as the map's value.
We will create a <select> element in our jsp and use the key-value pairs in the productMap to create the <option> tags for the <select> element.
The productMap's key will be the value and the productMap's value will be the text display of the <option> tag. So the productMap's value will be the one shown on the drop down display of the <select> statement.
You will need to create a reference to your Java bean in your JSP using the <bean:define> tag. In this example, we create a reference to the Java bean with the id 'cartVB'.
Then you will need to set a reference for the bean's map property 'cartVB.productMap' to a JSTL variable 'productMap'.
You can then iterate thru the map's elements using the <c:forEach> JSTL tag . You may also use the <c:remove> tag to clear and initialize the JSTL variable but it is optional.
<bean:define id="cartVB" name="cartViewBean" type="com.mycompany.view.CartViewBean"/> <c:remove var="productMap"/> <c:set var="productMap" value="${cartVB.productMap}" /> <select> <c:forEach var="product" items="${productMap}"> <option value="<c:out value="${product.key}" />"> <c:out value="${product.value}" /> </option> </c:forEach> </select>
