web-services - Axis2 Web 服务客户端失败 AxisFault : Address already in use: NET_Bind

Question

我正在使用 Axis 2 和 tomcat maven 插件(使用 Eclipse 嵌入式 Maven 启动)开发 Web 服务。出于测试目的，我使用 AXIOM 开发了一个 Web 服务客户端。

当我在我的系统 (Windows 7 Pro) 上运行客户端时，我遇到了各种行为，其中大部分是失败的:

极少数情况下，客户端程序能够成功访问到web服务。

Web 服务和客户端程序运行良好，我在其他计算机(仍然是 Windows 7 Pro)上测试了两者。当我从另一台计算机成功运行 Web 服务客户端时，它也有效。

这里是 pom.xml 中 tomcat 插件的定义:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>        
    <dependencies>
      <dependency>

        <contextFile>${basedir}/src/test/resources/tomcatconf/context.xml</contextFile>
        <!-- 
        <configurationDir>${basedir}/src/main/tomcatconf</configurationDir>
         -->
    </configuration>
    <executions>
      <execution>

        <phase>pre-integration-test</phase>

          <goal>run</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

网络服务客户端程序:

  static String address_WS   = "http://localhost:9966/services/GetGedFile";

  /**
   * @param args
   */
  public static void main(String[] args) {

    final EndpointReference targetService = new EndpointReference(address_WS);

    /* ... */

    try {
      Options options = new Options();

      ServiceClient client = new ServiceClient();
      options.setTo(targetService);
      options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
      options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, "true");
      options.setTimeOutInMilliSeconds(360000);

      client.setOptions(options); 

      OMElement result = client.sendReceive(serviceOp);

      String response = result.getFirstElement().getText();
      System.err.println("WS call result: " + response);

      OMNode node = result.getFirstElement().getFirstOMChild();
      if (node instanceof OMText) {                  
        OMText txt = (OMText) node;                  

        String data = txt.getText();
        byte[] dataBytes = Base64.decode(data);

        String realString = new String(dataBytes,"UTF-8");
        System.out.println("pseudo binary data received : " + realString);
      }

    } catch(AxisFault af) {
      af.printStackTrace();
    } catch (UnsupportedEncodingException e) {
      e.printStackTrace();
    }
  }

我曾尝试清理 Windows 服务、停止防病毒、使用其他端口(不同于端口 9966)、用 IP 地址替换 localhost : 都是徒劳的。我已使用 TCPView 监控我的系统，以检查 axis 网络服务是否使用与 tomcat 插件中配置的端口相同的端口。

还有其他想法吗？

我的问题是通过更改客户端程序的 java 运行时解决的。我使用的是 IBM Jdk 5(这是 Web 服务服务器的要求)，我切换到标准 Jre 6。
