Question

我已经编写了一个web服务，它在UI上运行得非常好，并且所有单元测试都在通过。我能够从Webservice发送请求和响应。

但是当我检查服务器日志时，我会看到这种堆栈跟踪。有没有人早先见过这个例外？

我正在使用AXIS2，Java 6和tomcat 6。

java.lang.ClassCastException: org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver cannot be cast to org.apache.axis2.engine.MessageReceiver

当从不同的类加载器加载类时会发生这种情况。

确保类路径上只有一个axis2 JAR，并且您的应用无法从同一服务器上的其他应用中看到Axis2 JAR。

使用AXIS2运行Web服务时，tomcat服务器日志中的java.lang.ClassCastException
