jmx(soap协议)连接websphere,服务器端启用了全局安全性

我在xp本机安装了websphere,并启用了全局安全性,服务器端的配置都是默认的
然后使用adminclient,通过soap协议去连接服务器,代码如下:
Properties props = new Properties();     
     props.setProperty(AdminClient.CONNECTOR_HOST, "192.168.0.11");
     props.setProperty(AdminClient.CONNECTOR_PORT, "8880");
     props.setProperty(AdminClient.CONNECTOR_TYPE, AdminClient.CONNECTOR_TYPE_SOAP);
     props.setProperty(AdminClient.CONNECTOR_SECURITY_ENABLED, "true");
     props.setProperty(AdminClient.USERNAME, "admin");
     props.setProperty(AdminClient.PASSWORD, "admin");
     props.setProperty("javax.net.ssl.trustStore", "C:/Program   Files/IBM/WebSphere/AppServer/profiles/AppSrv01/etc/DummyClientTrustFile.jks");
  props.setProperty("javax.net.ssl.keyStore", "C:/Program Files/IBM/WebSphere/AppServer/profiles/AppSrv01/etc/DummyClientKeyFile.jks");
  props.setProperty("javax.net.ssl.trustStorePassword", "WebAS");
  props.setProperty("javax.net.ssl.keyStorePassword", "WebAS");
   
  try {
   adminClient = AdminClientFactory.createAdminClient(props);
  } catch (ConnectorException ex) {
   ex.printStackTrace();
  }

这段程序在本机可以正确执行.但当在局域网的另一台机器运行时,却出现了异常,如下:
com.ibm.websphere.management.exception.ConnectorException: ADMC0053E: 启用 SOAP 连接器安全性时，系统无法创建连接到端口 8880 上的主机 192.168.0.11 的 SOAP 连接器。

到底是什么原因了,找了很久了,难道是soap不支持远程连接，还是说服务器端需要额外的配置(我也试了n种,但都没成功),
找了挺多文章也没找到原因.希望做过的指点下,提供建议也很感激.
