我正在使用 Jboss 5.0.1、jdk 1.6.0 更新 31 并将 EJB 实现为 Web 服务,并且我在 Web 服务模块中的方法在我的示例 BenefitLevel 数组对象中返回一个 JavaBean 对象数组。在 JBoss 中执行时会抛出以下异常:

我的 Web 客户端代码如下:

       <body>

         try
                           {
                        InitialContext ic = new InitialContext( );
                        CarrierWS carrierws = (CarrierWS)ic.lookup("java:comp/env/service/CarrierWS");
                out.println("========================" + carrierws);
                 CarrierWSSEI sei = carrierws.getCarrierWSSEIPort();
                  out.println("Invoking the service please wait ............." + carrierws.getCarrierWSSEIPort());
                ((Stub)sei)._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY,"http://localhost:8080/TestWS3WAR/CarrierWS");
                out.println("Invoking the service please wait ............." + sei.getActiveBenData().length);

             }
               catch(Exception e)
                                  {
                 out.println("Exception occurred : " + e.getMessage());
                  e.printStackTrace();
             }

             %>
        </body>
   </html>

请帮助我哪里出错了。

至少在 Jboss 5.0.1 GA 中,用户定义的数据类型不能在 Web 服务中返回。

用户定义的数据类型必须转换为字符串或字符串数​​组,反之亦然。
