ServiceClass对象未以下列形式实现所需的方法:OMElement add(OMElement e)

Question

我无法弄清楚错误发生的位置.我检查了我的Axis2.xml,我安装了最新的Axis2 API.我目前正在使用Apache Tomcat 8和JDK 1.8进行开发.

Exception in thread "main" org.apache.axis2.AxisFault: The ServiceClass object does not implement the required method in the following form: OMElement add(OMElement e)
    at org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:508)

我遇到过同样的问题

我通过更新WSDL版本解决了它,如下所示

http://www.w3.org/ 2004/08/wsdl/in-only - > http://www.w3.org/ ns/wsdl/in-only

&

http://www.w3.org/ 2004/08/wsdl/in-out - > http://www.w3.org/ ns/wsdl/in-out

示例services.xml

前

<service name="Axis2HelloWorld" >
    <Description>
        Please Type your service description here
    </Description>
    <messageReceivers>
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
        <messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </messageReceivers>
    <parameter name="ServiceClass" locked="false">com.ciber.webservices.Axis2HelloWorld</parameter>
</service>

新

<service name="Axis2HelloWorld" >
    <Description>
        Please Type your service description here
    </Description>
    <messageReceivers>
        <messageReceiver mep="http://www.w3.org/ns/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
        <messageReceiver  mep="http://www.w3.org/ns/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </messageReceivers>
    <parameter name="ServiceClass" locked="false">com.ciber.webservices.Axis2HelloWorld</parameter>
</service>

面临同样的问题。对WEB-INF-> services-> MyService-> META-INF-> services.xml进行以下更改

从：

<messageReceivers>
		<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
		<messageReceiver  mep="http://www.w3.org/2004/08/wsdl/in-out"  class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</messageReceivers>

至：

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