(bean-)property gets out of scope/session?
I'm fairly new to Struts, java and servlets so maybe it's a stupid question
but I have this problem:
Based on the pattern that is used by Steve Raeburn in his struts-examples, I
start my web-application with a prepareAction in which I declare
ArrayList codering= new ArrayList();
codering.add("NA");
codering.add("NF");
request.setAttribute("codering",codering);
I then forward to
return mapping.findForward("success");
which redirects to Search.jsp
In Search.jsp I want to use this code:
<html:select property="landCode" >
<html:options name="codering" />
</html:select><BR>
Tomcat however complains:
org.apache.jasper.JasperException: Cannot find bean under name codering
If I replace <html:options> with <html:option>-tags the Search page gives no
problem.
As far as I understand the Struts-architecture, request.setAttribute and
request.getAttribute are complimentory.
In his code-examples, I can't find any directives that could serve to
include the bean (jsp:useBean?)
Maybe I'm overlooking something but who has any thoughts?

or
<html:select size="13" property="subject">
<html:optionsCollection
property="myCollection" value="key" labelProperty="label">
</html:options>
</html:select>
You don't even have to specify value="key" and labelProperty="label"
if the bean in your array list has 2 properties "key" and "label" as
Hakan said.
Take a look at the doc here:
http://jakarta.apache.org/struts/userGuide/struts-
html.html#optionsCollection

SV: (bean-)property gets out of scope/session?
Posted by Håkan Fransson <hn...@ladok.umu.se>.
I'm using the collection attribute instead. The collection is an ArrayList
of individual beans with properties "key" and "label".
<html:select size="13" property="subject">
<html:options
collection="<%= CourseCatalogueJSPAttributes.JSPATTRIBUTE_SUBJECT %>"
property="value" labelProperty="label">
</html:options>
</html:select>
