nonsense ClassCastException
I'm trying to run some routes in tomcat using the servlet component
(CamelHttpTransportServlet in the web.xml)
In a simple example I've got it running fine, but when I try this in the
real example I get a startup exception that makes no sense at all.
Marking servlet CamelServlet as unavailable
Servlet [CamelServlet] in web application [/job-services] threw load()
exception
java.lang.ClassCastException:
org.apache.camel.component.servlet.CamelHttpTransportServlet cannot be
cast to javax.servlet.Servlet

Clearly CamelHttpTransportServlet can be cast to javax.servlet.Servlet.
Anyone got any ideas what to look at for this?

Yes, seems so. I fixed it by managing the dependencies, but what was
happening made no sense to me as two seemingly "identical" setups
behaved differently.

Hi,
It looks like you have incompatible Servlet API jars included in your WAR.
So your jars do not match the API used by your Tomcat.
Cheers!
