File Upload JSP

[Rohit Malhotra]

Hi,

I have written a JSP for File Upload which has a form element
<"FORM ENCTYPE="multipart/form-data">
<input type="submit" name="option" value="upload">
<input type="submit" name="option" value="check-in">
</form>
the problem is now. i want to check which button is clicked. by request.getPArameter("option"); however. it does not return any value since the enctp is mulipart/form. Can anyone please let me know how can i check which button is clickd?
Reggards,

How are you parsing the multi-part request? With your own code, or a 3rd-party package?

[Rohit Malhotra]

I am using a third party tool typically FileUpload jar from apache.

The fileUpload component has a guide here that demonstrates how to retrieve the standard request parameters.

[Bear Bibeault]

The documentation of your upload package should tell you how to obtain the non-file parameters. If your package doesn't let you do that, try a different one.

onclick event of button write code to set the value in request/session object

And how exactly do you propose he do that?

within jsp scriplet write
request.setAttribute("todo","upload");

in onclick event

That would be pointless. The onclick event is fired on the client as a Javscript event. Any scriptlet "embedded" in it would have been executed on the server before the page was even sent to the browser.
