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

Question

我正在尝试学习 WebServices (Axis2)

我正在使用 Jboss EAP 7.0、带有 JDK 8 的 eclipse_mars 和最新的 Axis2 (axis2-1.7.4)。

运行客户端代码时，

package com.durgasoft.service;

public class Test {
public static void main(String[] args) throws Exception{
    CalServiceStub stub = new CalServiceStub();
    //Code to invoke add()
    CalServiceStub.Add params =
    new CalServiceStub.Add();
    params.setI(13);
    params.setJ(10);
    CalServiceStub.AddResponse
    res = stub.add(params);
    int result = res.get_return();
    System.out.println(result);
    } 
}

我得到的错误是:

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)
    at org.apache.axis2.description.OutInAxisOperationClient.handleResponse(OutInAxisOperation.java:368)
    at org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOperation.java:414)

    at com.durgasoft.service.CalServiceStub.add(CalServiceStub.java:181)
    at com.durgasoft.service.Test.main(Test.java:12)

我查看了 StackOverFlow 上的以下帖子:

1. https://stackoverflow.com/questions/35720181/the-serviceclass-object-does-not-implement-the-required-method-in-the-fowingoll

   尝试更新 http://www.w3.org/2004/08/wsdl/in-only至 http://www.w3.org/ns/wsdl/in-only和 http://www.w3.org/2004/08/wsdl/in-out至 http://www.w3.org/ns/wsdl/in-out

2. 尝试在 service.xml 中添加操作标签，如 Simple axis2.xml for Axis2 embedded in webapp

3. 此外，我什至确保 Axis2.xml 中描述的 messageReceivers 和 service.xml 中提到的相同。我有 完全没有想法了。如果你知道怎么做，请帮助我 解决这个问题。

我已经创建了服务，

package com.durgaSoft.service;

public class CalService {

    public int add(int i, int j){
        return i+j;
    }
}

我用过eclipse wsdl生成工具来生成WSDL。生成的WSDL文件如下图所示。

我也遇到了这个问题，我解决了。

继续服务文件中的这条路径:

WebContent--> WEB-INF--> services--> ProjectName--> META-INF--> sevices.xml

之后更改此代码:

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

到:

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

并改变这个:

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

为此:

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

因为在 axis2.xml 文件中你使用的是这个 URL。所以检查并更改它。
