Actually the above is not what you probably want at all. The above is 
not going to write out the name of the property correctly. You probably 
mean something like...

<html:textarea 
property="someObject[${aProp.someIndex}].subobject[${bProp.someIndex}].someField"/>

I would disagree there. I love JSTL, but the nested tag is nice and 
makes things much cleaner.

Compare a JSTL version vs Nested tag version:

<%-- NESTED TAG WAY OF DOING IT: --%>

<nested:iterate property="departments">
     Department: <nested:text property="deptName"/><br/><br/>
     <div style="margin-left:10px">
         <nested:iterate property="employees">
             Employee: <nested:text property="empName"/>
             E-mail: <nested:text property="email"/><br/>
         </nested:iterate>
     </div>
     <br/><br/>
</nested:iterate>

<%-- JSTL WAY OF DOING IT: --%>

<c:forEach items="${companyForm.departments}" var="dept" 
varStatus="deptStatus">
     Department: <html:text 
property="departments[${deptStatus.index}].deptName" 
value="${dept.deptName}" /><br/>
     <div style="margin-left:10px">
         <c:forEach items="${dept.employees}" var="emp" 
varStatus="empStatus">
             Employee: <html:text 
property="departments[${deptStatus.index}].employees[${empStatus.index}].empName" 
value="${emp.empName}" />
             E-mail: <html:text 
property="departments[${deptStatus.index}].employees[${empStatus.index}].email" 
value="${emp.email}" />
             <br/>
         </c:forEach>
     </div>
     <br/><br/>
</c:forEach>
