Unable to scan WEB-INF for JAX-RS annotations

严重: Exception sending context initialized event to listener instance of class org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap

java.lang.RuntimeException: Unable to scan WEB-INF for JAX-RS annotations, you must manually register your classes/resources

因为web.xml配置了

        <listener>
<listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
</listener>

所以，出现这种错误，就是因为缺resteasy-jaxrs-2.3.3.Final.jar，添上就好了

居然还搞了半天才解决，贴在这里当做警告

配置后的工程开发环境：

jackson-core-asl-1.9.13.jar
jackson-jaxrs-1.9.13.jar
jackson-mapper-asl-1.9.13.jar
javassist-3.11.0.GA.jar
jaxrs-api-2.3.1.GA.jar
resteasy-jaxrs-2.3.1.GA.jar
scannotation-1.0.3.jar
servlet-api.jar

用jackson-core-asl-1.9.12.jar不能正常启动，必须1.9.13
