Class Cast error upon deploying Camel web app
Has anyone seen this error? I'm trying to deploy on JBoss6. I was
able to deploy before without issues. I guess
it's some kind of "classloader-Hell" issue due to JEE weirdness.

Actually, I forgot the baked-in xerces/xalan are in namespace javax.xml, but
the standalone xerces/xalan are in org.apache.
In any case, I added some other components which caused Maven to
pull in xalan-2.7.0 and there was already xalan-2.7.1 proved by JBoss,
so I added exclusions in the pom.xml
Thanks,
Chris

Thanks, I tried that and now the error as shown below.
Note that jboss6 was built with jdk-1.5, so it comes with it's own
xerces/xalan, so I'm
thinking there's a class with the JRE baked-in xerces/xalan (I'm running with
jre-1.6). On the other hand, I have been able to deploy successfully
before and I did
even without the special camel-jboss classloader. So do I need that?

Hi
I assume the JAXB version being provided by JBoss 6 is pretty outdated and
not really compliant with Camel 2.10.4 as JBoss 6 is from end 2010.
Do you have any jaxb-impl inside your WAR/EAR being included? If not maybe
try to add the following dependency inside the POM of your Web-App so that
jaxb-impl-2.1.13.jar gets included into your WEB-INF/lib folder of your WAR
getting precedence to the one from JBoss AS.
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.1.13</version>
</dependency>
