eui怎么让动作条变大:jsp中调用webservice 代码

public String sayHello(){

    return "Hello world!";

   }

调用方法如下：

////////////////////////////此方法调用webservice的方法，返回值/////////////////////////////////////
  public String getString()
     {
          String ret = null;
         try
         {
              String endpoint =
                     "http://localhost:8080/LSA/services/test";
              Service service = new Service();
              Call call = null;
              call = (Call) service.createCall();
              call.setOperationName(new QName(
                     "http://localhost:8080/LSA/services/test",
                     "sayHello"));
              call.setTargetEndpointAddress(new java.net.URL(endpoint));
              ret=(String)call.invoke(new Object[]{});

          }catch(Exception e)
         {
              e.printStackTrace();
          }
         return ret;
      }
/////////////////////////////////////END//////////////////////////////////////////////

调用带参数的webservice

public void getString()
     {
          String ret = null;
         try
         {
              String endpoint =
                     "http://localhost:8083/Receive/services/AddUser";

              Service   service = new Service();
              Call call = null;
              call = (Call) service.createCall();
              call.setOperationName(new QName(
                     "http://localhost:8083/Receive/services/AddUser",
                     "AddUser"));
              call.addParameter("BH",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);
              call.addParameter("MM",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);

             //call.invoke("1");

              call.setTargetEndpointAddress(new java.net.URL(endpoint));
              ret=(String)call.invoke(new Object[]{"2","2"});


          }catch(Exception e)
         {
              e.printStackTrace();
          }
         //return ret;
      }
