I try to extend my RESTful web service in an EAR as follows:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
<interceptors>
<class>org.jboss.seam.rest.validation.ValidationInterceptor</class>
</interceptors>
</beans>
However, I'm getting a stacktrace as described in https://issues.jboss.org/browse/AS7-1100 .
