I am following your suggestion. I put my "while" loop
in the <c:forEach ...> tag, and I have changed
<%=threadBean.getSender()%>
to
<c:out value="${threadBean.sender}" />
There is a situation which I do not know how to
handle.
Inside the <c:forEach .... > tag, I have a line of
code:
<%=SiteUtil.filter( threadBean.getPostTopic(),
false/*html*/, true/*emotion*/, false/*mvnCode*/,
false/*newLine*/, false/*URL*/ )%>
This JSP expression calls a method 'filter' in another
class SiteUtil.java. And one of the properties
(postTopic) of the threadBean is passed as a parameter
to that method.
How do I use the <c: .......> tag in the above JSP
expression?
Thank you in advance.
