I'm trying to expose my web service by extending SpringBeanAutowiringSupport. I'm using GlassFish 3.1 and Spring 3.0.5.RELEASE.

I'm following the tutorial [here](http://www.javacodegeeks.com/2010/11/jaxws-with-spring-and-maven-tutorial.html).

However, **when I go to the URL of my web service I get a ClassCastException.**

Any ideas on what I'm missing or doing wrong?

```
