java ServiceClass 对象未实现以下形式的所需方法：OMElement add(OMElement e)

The ServiceClass object does not implement the required method in the following form: OMElement add(OMElement e)

提问by dodger

I am unable to figure out where the error is occurring. I checked my Axis2.xmland I have installed the latest Axis2 API. I am currently using Apache Tomcat 8 and JDK 1.8 for development.

我无法弄清楚错误发生在哪里。我检查了我的Axis2.xml并且已经安装了最新的 Axis2 API。我目前使用 Apache Tomcat 8 和 JDK 1.8 进行开发。

Yeah I did. I finally figured out that in Axis2.xml we need to add

是啊，我做了。我终于想通了，在Axis2.xml中我们需要添加

<messageReceiver mep="w3.org/ns/wsdl/in-only"; class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" /> <messageReceiver mep="w3.org/ns/wsdl/in-out"; class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />

<messageReceiver mep="w3.org/ns/wsdl/in-only"; class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" /> <messageReceiver mep="w3.org/ns/wsdl/in-out"; class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />

This snippet to make it work. I am not sure why this is important instead of default

这个片段使它工作。我不确定为什么这很重要而不是默认

<messageReceiver mep="w3.org/ns/wsdl/in-only"; class="org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver"/> <messageReceiver mep="w3.org/ns/wsdl/in-out"; class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>.

<messageReceiver mep="w3.org/ns/wsdl/in-only"; class="org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver"/> <messageReceiver mep="w3.org/ns/wsdl/in-out"; class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>.

Thanks everyone for your prompt replies. Really helped me a lot to figure out what had to be done.

感谢大家的及时回复。真的帮助我弄清楚必须做什么。
