I'm trying to get the stock portfolio example from the book Rich Internet
Applications with Adobe Flex and Java to work with Flex Builder 3 and Flex Data
Services 2.6 under JBoss. The book was written for Flex 2 and Flex Data
Services 2 so maybe I need to modify something for the latest versions of those
products.

The .war file deploys on JBoss without any problems, but when I go to the URL
I get this error:

Error: No class registered for interface 'mx.styles::IStyleManager2'.

I have no idea why it is referring to an E: drive since I don't use one.
Maybe this is some artifact from Adobe's build of its libraries.

Does anyone have any idea what my problem is?

Thanks.
