Geting 500 Internal error

[Praf]

I have application develpoed in using Javascirpt and Ajax functionality. Scenario is that when I clicked on Ajax functionality button on a search of a particular function it populates list from DB but when I pressed enter button instead of clicking Ajax button, then it shows error message as Webpage cannot be dispayed. Can anyone suggest a answer for this why it is not working properly when i pressed enter button, but working properly by clicking Ajax button.

When you press enter is it submitting your form?

No it was not submitting form, later i did changes in Internet option to get exact error message and i got below error message -->
500 Internal Server Error
Servlet error: Request[/CustomerMonDestAssignmentView] does not contain handler parameter named 'method'. This may be caused by whitespace in the label text.

How nice of them to suggest a cause. Is there whitespace in the label text, or is the server just babbling?

What does happen when you click Enter? If you haven't programmed it out explicitly, it may try to use a default-- probably involving values that you haven't set. (MSIE seems to be especially fond of pulling random NaN values out of a hat instead of just playing it safe with zero.) The 500 error is pretty extreme, though. Usually when I make a mistake in javascript the program just pretends it isn't there at all.

Praf, this may help - a 500 error can't be caused by Javascript or Ajax alone. Javascript and Ajax are client-side technologies, that is, they are all executed in the browser. Whatever location your Ajax is sending to on the server is the point of error which is why penders asked:

is it submitting your form?

... whether it's a form or a "get parameter," the problem is in how the server is processing it. So work backwards from there: server errors <- my Ajax is sending malformed data so it can't process it.
