There are a few problems with your code.
First is the fact that any object used in a
struts tag must be in some scope (either page, request, session, or application). It's not enough just to declare a scriptlet variable. So, your scriptlet should look like this:
This code puts the array in page scope, so now it's available to a Struts tag.
The second problem is that you're using the wrong attribute of the html:options tag. If you've got a collection of Strings and you want each String to be both the label and the value of the option, you simply specify the name of the collection or array as the
name attribute. So, your html:options tag should look like this:
Regarding the difference between html:options and html:optionsCollection, here is the rule I generally use:
If you've got an array or collection of strings that represent both the label and the value of the option, use html:options just like I showed you in the example above.
If you've got a collection of JavaBeans for which one bean property represents the label and another represents the value, use html:optionsCollection. Example:
In the above example, the LabelValueBean has a
label and a
value property.
