How to iterate Set elements using Struts 2 tags

Question

I have two Sets

set1  contains("A","B","C","D") elements
set2  contains("E","F","D","G") elements

I want to compare every element of set1 with every element of set2 and display matched elements using Struts2 tags.

Answer 1

Try the code below:

<s:iterator var="val1" value="set1">
 <s:iterator var="val2" value="set2">
  <s:if test="#val1 == #val2">
   <s:property /><br>
  </s:if>
 </s:iterator>
</s:iterator>
