無法使用Apache axis2和寧靜的Web服務通過客戶端代碼訪問Web服務

Question

我使用Axis2創建了一個寧靜的Web服務。 我在服務器上部署了.aar文件，當我嘗試通過axi2服務使用url訪問該webservice時，它顯示了我在webservice中使用過的java頁面中的錯誤，例如：

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

但是，當我嘗試使用一些嘗試訪問帶有請求參數的URL的客戶端代碼時，其說法是：

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

我正在使用OMElement進行請求和響應創建

你好servlet是

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

您能幫我嗎...我花了很多時間來建立圖書館...並解決了類路徑

Answer 1

我想通了。 實際上，我需要配置axis2.xml文件：

在郵件格式化程序中，應添加

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

在郵件生成器中

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

這解決了我的問題。 希望它能幫助別人。
