JSP and Servlets

[isi.catch]

Hi all...

I actually have two questions...

1)

I want to display certain messages depending upon the option selected in the combo box. As soon as the option is selected i want the corresponding messages to be displayed. That is I dont want to use submit button. I think this can be done in javaScript but im not sure how

2)

how do i upload a file from the users system into a folder on the server side??


Thanks in advance...

For the file upload take a look at this.

It sounds like you're looking for AJAX (Asynchronous Javascript And XML). It's quite easy to do. In short, you implement a few functions that work with a specific object (unfortunately different ones, depending whether it's IE or not). Then you tie it to an onClick() (or equivalent).

Alternatively, you could just use onClick() (or equivalent) to call a method to change it (this is only if you don't need to continuously check for changes to the data you want to display).
