Question

我尝试使用axis2设置网络服务。我使用Apache Tomcat 7和动态Web版本2.5在Eclipse下创建了一个Dynamic Web Projet。我已将Axis 2 Facets添加到配置中。

我有以下课程：

package com.jo.ws;

public class Test {
    public int add(int a, int b) {
        return a + b;
    }
}

然后我使用Bottom up Java bean Web Service为projet创建了一个WebService，并将我的Test类添加到服务实现中。我选择了＆＃34;开始服务＆＃34;在滑块中，并将配置中的Apache Axis更改为Axis 2.然后，我使用默认选项生成默认的services.xml文件。

我可以通过以下地址访问我的项目：

http://localhost:8888/Axis2WS/

这会显示Axis 2页面，我可以看到我的服务处于活动状态

 http://localhost:8888/Axis2WS/services/listServices

正确生成并显示wsdl

如果需要，我可以发布。

但现在如果我这样做：

http://localhost:8888/Axis2WS/services/Test?method=add&a=2&b=1

我明白了：

<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Text xml:lang="en-US">wrong number of arguments</soapenv:Text>
</soapenv:Reason>

我的Eclipse控制台日志中也出现了错误，包含以下堆栈跟踪：

知道我做错了什么吗？

感谢您的帮助！

错误来自我在浏览器中输入的网址.. 调用该方法的正确URL是：

http://localhost:8888/Axis2WS/services/Test/add?a=3&b=2

您需要更换＆＃34;？＆＃34;用＆＃34; /＆＃34;在方法名称之前，然后在添加＆＃34;？＆＃34;之后写下参数。在您的方法名称之后
