public class OptionsHolder {
Map options = new HashMap();
public OptionsHolder() {
options.put("key1", new LabelValueBean("foo","key1"));
options.put("key2", new LabelValueBean("foo","key1"));
}
public Collection getOptionsCollection() {
return options.values();
}
public Map getOptionsMap() {
return options;
}
}You can then use the getOptionsCollection() method to render the options in the first form. Then in the page where you want to display the value for the key, you can use JSTL. Assuming the ServletContext attribute name were "optionsHolder" and the key was in the property 'key' on the form:
<c:out value="${optionsHolder.optionsMap[MyForm.key]}"/>Another alternative is to create a mapped property in the OptionsHolder bean; then use Struts support for mapped properties in the bean:write tag.
Finally, a third alternative would be to fetch the value in the action that processes the form. Extract the desired value then set it as a request attribute for display on the subsequent JSP. With this approach you might not need to use the OptionsHolder class and instead just iterate over the collection looking for a match.

I've loaded a collection of valid options and their descriptions as a ServletContext attribute, for use in an <html:options> tag. It works as intended in a generated html <select> tag. Once a user selects an option, the option value (rather than the description) is recorded in a form bean, and the form bean is forwarded to another form. So far so good.
What I'd like to do in the next form is display the description of the selected option, using the option as a lookup key to the original collection. Is there an existing struts tag that will allow me to do this?
