Atlas/JavaScript getting started problem

I'm trying to get started with Atlas and associated necessary javascript at
the same time. I started out at
http://atlas.asp.net/walkthroughs/gettingstarted/basic.net where they have
an application (which I have pasted below) that displays a string returned
from a web service.

One problem is that the application doesn't work. It errors out at....

Samples.AspNet.HelloWorldService.HelloWorld(SrchElem.value,OnRequestComplete);

saying that Samples is undefined. Can anyone tell me what is wrong?

Another thing I'm curious about is that the author of the article said it
was necessary to NOT use a codebehind file but did not say why. Why can't a
code-behind file be used?

Thanks,
T

I am not sure what your web service code looks like, but you may have an
issue with the namespace name. If you could post that code, that would be
great.

As for the code-behind comment, I believe the author was stating that you do
not need to use the code behind for the ASPX page. Since atlas is calling a
web service you may or may not need to implement any code-behind for your
aspx page. If you are not performing any post back routines then you wouldn’t
necessarily need any code behind.

It is definitely the namespace -- I had the same error.

Change:
Samples.AspNet.HelloWorldService.HelloWorld(SrchElem.value,
OnRequestComplete);
to where ever your web service is located in your project -- mine was just

HelloWorldService.HelloWorld(SrchElem.value,OnRequestComplete);
