If my collection is in my form bean, this is how I would do it in the JSP:
<bean:define id="myCollection" name="myFormBean" property="myCollectionField" />
<html:options collection="myCollection" property="myValueField"
labelProperty="myLabelField" />

If bean X is already instantiated and in the request/session, then all you would have
to do is change your <bean:define> tag to reference the attribute name of bean X:
// do this in your action somewhere
request.setAttribute("beanX", new BeanX() );
// and this in your JSP
<bean:define id="myCollection" name="beanX" property="myGlobalCollection" />
Note that if this utility bean is global to the web app., then you probably want to
put the bean into the ServletContext, so that it's only created once. Then you would
fetch it from the ServletContext in your action and stuff it into the request so it
can be accessed from your JSPs.

Not a dumb question. The docs for <html:options> are difficult to understand, and the
semantics for the tag's attributes are completely non-intuitive.
