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!
