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.

Re: Class Cast error upon deploying Camel web app
Hi I assume the JAXB version being provided by JBoss 6 is pretty outdated and not really compliant with Camel 2.10.4 as JBoss 6 is from end 2010.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 groupIdcom.sun.xml.bind/groupId artifactIdjaxb-impl/artifactId version2.1.13/version /dependency Babak Chris Wolf wrote Has anyone seen this error?

Re: Class Cast error upon deploying Camel web app
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? 20:18:03,218 INFO org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory [STDOUT] [...] Caused by: java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(Unknown Source) [:1.6.0_29] at org.springframework.beans.factory.xml.DefaultDocumentLoader.createDocumentBuilderFactory(DefaultDocumentLoader.java:89) [:3.1.0.RELEASE] at org.springframework.beans.factory.xml.DefaultDocumentLoader.loadDocument(DefaultDocumentLoader.java:70) [:3.1.0.RELEASE] at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:388) [:3.1.0.RELEASE] On Fri, May 3, 2013 at 5:15 PM, Babak Vahdat babak.vah...@swissonline.ch wrote: Hi I assume the JAXB version being provided by JBoss 6 is pretty outdated and not really compliant with Camel 2.10.4 as JBoss 6 is from end 2010.

Re: Class Cast error upon deploying Camel web app
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 On Fri, May 3, 2013 at 8:28 PM, Chris Wolf cwolf.a...@gmail.com wrote: Thanks, I tried that and now the error as shown below.
