Read XML file-->listDropdown

[renu richard]

Hi,
I have three dropdown boxes in a JSP. The values to be populated in the drop down list are available in the XML file. Once the value is selected in th first drop down list, it has to display the the correspoding values in the second box after reading the mapped values from the XML and so on.
Can anyone tell me how can i achieve this.

Use XML Parsers to get the lists and show in drop donw list and for loading another drop down lists use Ajax.

Let me know if im not clear

Rajani,
I am familiar with JSP's. But i dont know anything about AJAX. Could you please refer me to any URL's where i could see similar kind of sample code or where i can learn aout AJAX. Also is it not possible to achieve this functionality with javascript alone.(not using AJAX)

Start with this article to learn how Ajax works. Then adopt a library such as jQuery or Prototype to do your Ajax for you.

Also is it not possible to achieve this functionality with javascript alone.(not using AJAX)

Not unless you preload all possible values on the page in JavaScript variables in advance.

I hope this one Implementing Ajax in Java web application using JQuery helps.

Yes , with out Ajax also you can implement it.The only problem is you need to submit the entair form to the server.Just call another action if any one selects one item from first dropdown list.

If you want any simple ajax example please gothrough the following link

But this is for beginers....
