Right from the box, no. You'll have to write a bean that reads your data from the database and put it in two arrays (one for values, other for labels) or collections. Then, you can use the and tags to create the combobox and populate the option from the arrays. The main idea of struts is to separate presentation (your combobox) from the data, so the need for an intermediate bean (the controller) to manage them. Pierre Métras

Hi Pierre, Thanks a lot.I am going through the docs to look at the usage of the select and option tags. Once again thanks a lot for that quick response!!!

Re: Support for ComboBox
Again on the ComboBox, How should the arrays be passed to the jsp page. I can think of a couple of ways to do it. 1. Could be passed through the session object. 2. Could be instantiated as part of the ActionForm. Could someone please throw some light on this. Thanks.

Re: Support for ComboBox
It depends of how persistent are the data you want to put in you Combo., e.g. if you have to fill in a combo with countries, this will not change during your application so you could put it in the session or even in the application scope, but for data that have to change a lot it's maybe a good idea to put them in the request scope and so to fill the data in the ActionForm Thierry Cools Senior Java Developer S1 Brussels Kleine Kloosterstraat, 23 1932 st.
