Re: options-Tag

[Ted Husted]

The simplest thing is to use the LabelValueBean class provided by the example.   In your Action, a database query (or equivalent) would create a collection of LabelValueBeans, and then insert the collection into the request context.   First, the database query executes a query and returns the rowset as an instance variable named list..   Then you can transfer the rowset to a collection (e.g. ArrayList)     public ArrayList fetchList() throws SQLException {     if (result==null) { return (null); }     else {       String defaultValue = "1980"; // FIXME - YEAR       String defaultLabel = "ALL"; // FIXME       ArrayList list = new ArrayList();       list.add(new LabelValueBean(defaultLabel,defaultValue)); // Defaults at top of the list       while (result.next()) {         String year = result.getString(1);         list.add(new LabelValueBean(year, year));       }       return(list);   }   And,   request.setAttribute("salesYears",salesYearsList);   There is a working example of this using a DISTINCT query in "Struts with a Fruit Glaze", found at < http://husted.com/about/struts >   I haven't tried it, but I think the part about "only property" refers to whether the label (in the drop down) use the same or different labels. *********** REPLY SEPARATOR *********** On 1/15/2001 at 11:28 PM Johann Dorn wrote: Hello,   I have some problems with the options tag, which I want to use in conjunction with my ActionForm.     In the example application the collection is filled directly in the subscription.jsp <%-- In real life, these would be loaded from a database --%> <%   java.util.ArrayList list = new java.util.ArrayList();   list.add(new org.apache.struts.example.LabelValueBean("IMAP Protocol", "imap"));   list.add(new org.apache.struts.example.LabelValueBean("POP3 Protocol", "pop3"));   pageContext.setAttribute("serverTypes", list); %>         According to the Documentation the options-Tag can be used in a different way: - The ActionForm  bean can contain the collection, - Only property is specified - The value of this attribute is the name of a property of the ActionForm bean associated with our form, which will return the collection.     But I alwas get expceptions like 'javax.servlet.ServletException: Cannot create iterator for PersForm@dafb2f4a'     Can anyone give me an example or some hints how the options-Tag must be used in conjunction with the ActionForm?     Best Regards Johann Dorn
