Caroline - I have 3 suggestions.
The first is to make sure that you are using the correct form name in your html:form, and that the form definition is setup correctly in struts-config. The error message you are getting seems (to me at least) suspiciously like it can't find a form property named "anything" in the form you are trying to load up.
The second is to make sure that PageBean has getters/setters for all of its properties, and that it has a valid default constructor.
The third is to try and take the page import="bla" out of the page, and instead set a request variable with the bean data in you loader action. I've never tried doing it using the page import myself, so it may work (maybe somebody else can chip in on that...) but I've definitley had success with the other way.

<html:select size="1" property="anything" multiple="false"> <html:options collection="PageBeans" property="name" labelProperty="name"/> </html:select>
and my way:
<%@ 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>
Both ended with the same 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 --- Amin Lalji <[EMAIL PROTECTED]> wrote:
Try removing the bean:define
And setting your line:
<html:options collection="nameList" property="name" labelProperty="name"/>
to:
<html:options collection="PageBeans" property="name" labelProperty="name"/>
HTH, Amin

Subject: Hate Myself for Not Getting Drop-Down Menu
Right
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 coded some drop-down menu before. This time, I have a collection of JavaBeans instead of a collection of strings. And, I am in trouble again.
I passed a collection of JavaBean(s) upon successful completion of an action:
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 the listpages.jsp, I imported:
<%@ page import="org.dhsinfo.content.PageBean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %> <%@ taglib uri="/tags/struts-bean" prefix="bean" %>
To form a drop-down menu, I did:
<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>
I got this error:
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
