Hi Ding!
You can try this:
<bean:size id="collectionLength" name="dsmccList" />
You may look into struts-bean API documentation to understand how this tag works.

Subject: How to get length of an array(collection)
Hello all,
There is an array(dsmccList) obtained by a self-defined tag, and I wanna to send the
length of the array
as an hidden property, as following:
<iPanel:appListData id='dsmccList'/>
<c:set var="dataCount" value="${dsmccList.length}"/>
But this causes exception:
javax.servlet.jsp.el.ELException: The "." operator was supplied with an index value
of type "java.lang.String" to be applied to a List or array, but that value cannot be
converted to an integer.
Any ideas? Thanks!
