Hi all, I've just downloaded and unzipped the JBossAS 5.0.0CR1 package, and eager as I am, I immediately started it using bin\run.bat. This error appeared on the console: 14:58:48,222 ERROR [AbstractKernelController] Error installing to Create: name=ManagedConnectionFactoryParserDeployer state=Configured | java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from vfszip:/C:/Java/jboss-5.0.0.CR1/lib/jaxb-impl.jar/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader.
