How to iterate an ArrayList of object array using JSTL?

I have a list of object array like this.

List<Object[]> reqUserDetails = new ArrayList<Object[]>();

Now I have to iterate this list and take values like Object[0],Object[1].... How can I do this using JSTL?

The general syntax is to itearate it like ,

<c:forEach items="${outerList}" var="innerList">
  <c:forEach items="${innerList}" var="item">
     // Print your object here
  </c:forEach>
</c:forEach>

and in your case , 

<c:forEach items="${reqUserDetails}" var="firstVar"> 
      <c:forEach items="${firstVar}" var="secodVar"> // firstVar will hold your object array
         <c:out value="${secondVar.field1}" /> // on iterating the object array 
      </c:forEach>
  </c:forEach>

as it contains array of objects inside the List . so the outerList will hold the Object[] which you need to iterate again.

Hope this helps !!

From controller: 

List<Object[]> reqUserDetails = new ArrayList<Object[]>();
request.setAttribute("reqUserDetails", reqUserDetails);

And from view side, you can iterate your list as per your requirement.

  <c:forEach items="${reqUserDetails}" var="objectList"> 
      <c:forEach items="${objectList}" var="object">
      <tr>
        <td>${object.field1}</td>
        <td>${object.field2}</td>
        <td>${object.field3}</td>
         ........
      </tr>
     </c:forEach>
    </c:forEach>
