我使用 Axis2 创建了一个安静的 Web 服务。我在服务器上部署了 .aar 文件，当我尝试通过 axi2 服务使用 url 访问该 web 服务时，它显示了我在 web 服务中使用过的 java 页面的错误，例如：

<getActivitiesResponse>
    <statusCode>300</statusCode>
    <statusMessage>NO_RESULTS_FOUND</statusMessage>
</getActivitiesResponse>

但是，当我尝试使用一些尝试使用请求参数访问 url 的客户端代码进行访问时，它会说：

  java.io.IOException: Server returned HTTP response code: 500 for URL

我正在使用 OMElement 来创建请求和响应

你好 servlet 是

<servlet>
    <servlet-name>helloServlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

你能帮我吗...我花了很多时间来构建库...并解决类路径

我想通了。其实我需要配置axis2.xml文件：

在消息格式化程序中，这应该被添加

<messageFormatter contentType="application/json"
        class="org.apache.axis2.json.JSONMessageFormatter" />
</messageFormatters>

在消息生成器中

<messageBuilder contentType="application/json"
        class="org.apache.axis2.json.JSONOMBuilder" />
</messageBuilders>

这解决了我的问题。希望它会帮助别人。
