Error Occurred When Using JSP Expression Inside Struts c:forEach Tag

[JiaPei Jen]

I am using the Struts framework. I have a JSP where a collection of JavaBeans are received in a request scope.

<%
Collection threadRows = ( Collection )request.getAttribute( "ThreadBeans" );
%>

Each of the JavaBeans, which I name it as ThreadBean, has a number of properties. In the beginning of my JSP and right after the <%@ page import="org.MyOrg.MyProj.message.ThreadBean" %>, I have

<bean:define id="threadbean" name="ThreadBean" type="org.apache.artimus.message.ThreadBean" scope="request" />

I iterate through the collection using the <c:forEach ....> tag:

<c:forEach id="threadBean" items="${threadRows}" varStatus="idx">
   <c:choose>
      <c:when test="${(idx.count+1)%2==0}">
         <tr bgColor=#EEEEEE>
      </c:when>
      <c:otherwise>
         <tr bgcolor=#FFFFFF>
      </c:otherwise>
   </c:choose>
    <td colspan="3">
        <a href="viewthread?thread=<c:out value="{threadBean.threadID}" />">
        <B>
        <%=SiteUtil.filter( threadBean.getPostTopic(), false/*html*/, true/*emotion*/, false/*mvnCode*/, false/*newLine*/, false/*URL*/ )%>
        </B>
        </a>
    </td>
    <td align="center">
        <c:out value="${threadBean.sender}" />
    </td>
    <td align="center"><c:out value="{threadBean.threadReplyCount}" /></td>
    <td align="center"><c:out value="{threadBean.threadViewCount}" /></td>
    <td align="center">
        by <c:out value="${threadBean.lastPostMemberName}" />
    </td>
</tr>
</c:forEach>
 

I have an expression in the <c:forEach .... >; tag. In that expression, I am calling the 'filter' method of another class SiteUtil.java (this class is also imported to my JSP). I have to pass one of the properties of the ThreadBean as a parameter to that 'filter' method; i.e. threadBean.getPostTopic(). And it is an error. My JSP cannot be compiled because of it.

What is the correct way of doing it?

My guess: eliminate the bean:define tag(s)

I have tried without the <bean efine ........> tag. I got the same error messages. Therefore, it is something else that caused the problem.
