Hi, thanks for the reply.
First, 'anything' is the property for the <html:select
....> tag; therefore, 'anything' has nothing to do
with my particular problem.
Second, There is no problem with the database
operation. Data are retrieved and can be displayed
using the <c:forEach ....> tag. Now, it is the
drop-down menu.
I have a collection of JavaBean(s) upon successful
completion of an action to pass onto a .jsp:
Collection pages = service.getPages();
request.setAttribute( "PageBeans", pages );
The individual JavaBean in the Collection is called
PageBean. The PageBean has only one property called
'name' (I made it simple for testing purpose) with the
get and set methods.
In my listpages.jsp, I have
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ page import="org.dhsinfo.content.PageBean" %>
<bean:define id="nameList" name="PageBeans"
scope="request" type="java.util.ArrayList" />
<html:select size="1" property="anything"
multiple="false">
<html:options collection="nameList"
property="name" labelProperty="name"/>
</html:select>
it ended with this error message:
Http Status 500 root cause
javax.servlet.jsp.JspException: Cannot find bean
under name org.apache.struts.taglib.html.BEAN
and in the Tomcat logs file:
2004-09-20 12:03:38
ApplicationDispatcher[/DHSInfo] Servlet.service() for
servlet jsp threw exception
javax.servlet.jsp.JspException: Cannot find bean under
name org.apache.struts.taglib.html.BEAN
