issue in iterating map type in struts2

Question

I've tried to iterate the variable of map type in jsp .. but the result page shows nothing

product details is of type Map<String,String>

//Action

public String execute() {
productDetails = displayServiceDao.fetchProductDetailsService( product );}
public Map<String , String> getProductDetails() {
return productDetails;   
}
public void setProductDetails( Map<String , String> productDetails ) {
this.productDetails = productDetails;
}

//jsp

<s:iterator var="studentEntry" value="productDetails.entrySet()">
<s:property value="%{#studentEntry.getKey()}"/>
<s:property value="%{#studentEntry.getValue()}"/>
</s:iterator>

Note:i am not adding values to map in action class..i add it through the return value of a function

I think you need to decide what you want to do with the keys and values in your map. You could do:

<s:iterator value = "productDetails" >
    <s:property value="key"/>
    <s:property value="value"/>
</s:iterator>

Nb this will iterate over the entrySet of you map and use a Map.Entry object which contains key and value properties.
