I have no problem to iterator the arrarylist
<s:iterator id="part" value="parts" status="st"> <<s:property value="pid"/><br> </s:iterator> but if i want to pass arraylist parts back to action, can i do following? <s:url action="KeywordprocessAction.action" var="keywordTag"> <s:param name="parts"> <s:property value="parts" /> </s:param> </s:url> <s:a href="%{keywordTag}">Keyword Process</s:a> thanks in advance john
