I'm getting this error while running my ASP.NET app on IIS7. I've tried doing what it says to do but it doesn't help. The WebResource.axd handler must be registered in the configuration to process this request. > <!-- Web.Config Configuration File --> > > <configuration> > <system.web> > <httpHandlers> > <add path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" validate="True" /> > </httpHandlers> > </system.web> > </configuration> I'm using a little bit of AJAX which is what I think is causing the issue. Has anyone encountered this before? I figured it out so I

Where exceptions occur in the UpdatePanels I've implemented in the ASP.NET web app I'm building, they cause a JavaScript error on the page with some high level error output available in the alert. This is OKish for development, but as soon as the system is in Production, it's obviously no good for multiple reasons. I can surround troublesome activities with Try Catch etc to control the Javascript error but in some cases, I want to take actions on the main page etc to support the user experience.

How can I use GWT together with Visual Studio to create an ASP.NET website? If it is possible. Thanks You can use GWT to generate the client side code writing in Java and use asp.net for the back end. It's a little trickier as you won't get the serialization across the wire for free that you'd get from using Java on the back end too. I wouldn't really recommend this approach it's bound to be a hassle to maintain. I'd recommend using a good javascript toolkit instead, such as jquery and jquery UI. GWT can be used with any back end with a little work. Out of the box it uses a servlet container
