Hi

You can use logic:iterate to loop  see the bellow example

<logic:iterate id="IdofYourBean" name="hashMap">
           <option value="<bean:write name="IdofYourBean" property="key"/>">
                      <bean:write name="BatchView" property="value"/>
           </option>
</logic:iterate>  

Note: Before using bean id use <bean:define> to define the property. And HashMap property should be in your bean with getter and setters.


Hope this will solve your problem :)

For further information on logic:iterate follow the link

JSTL is far better to use than the logic library. In fact the struts developers recommend it.

Iterating over a map is very simple

<c:forEach var='item' items='${map}'>
   <c:out value='Key=${item.key}, Value=${item.value}'/>
</c:forEach>

If the value is an ArrayList as you say then you just do another c:forEach on the value returned by item.value.

<c:forEach var='mapItem' items='${map}'>
   <c:forEach var='myListItem' items=${mapItem.value}'>
      <c:out value='${myListItem}'/>
   </c:forEach>
</c:forEach>
