DelphiXE7新建WebService具体操作：

1.打开“DelphiXE7”->“File”->“New”->“Other”

2.“New Items”－>“Delphi Projects”->“WebSrvice”->“SOAP Server Application”

3.“Stand-alone application”->“Next”

4.“VCL application”->“Next”

5.“8080”->“Finish”

6.“Create Interface for SOAPmodule?”->“Yes”

7.“Add New WebService”->输入服务名字“MyData”->“OK”

8.保存全部工程文件

9.在“WebModuleUnit1”单元中放入控件：

FDConnection1

FDPhysMSSQLDriverLink1

FDQuery1

DataSetProvider1

ClientDataSet1

10.双击FDConnection1->Definition->Driver ID:->“MSAcc”->Daabase->“E:\MyData.mdb”->LoginPrompt:=False->Connected:=True

11.FDQuery1->Connection:=FDConnection1->SQL:=“select * from usesr”->Active:=True

12.DataSetProvider1->DataSet:=FDQuery1

13.ClientDataSet1->ProvideName:=DataSetProvider1

DelphiXE7客户端具体操作：

1.打开“DelphiXE7”->“File”->“New”->“Other”

2.“New Items”－>“Delphi Projects”->“WebSrvice”->“WSDL Importer”

3.“Import WSDL”->WSDL Source中输入“http://localhost:8080/wsdl/IMyData”->“Next”

4.“Automatic SOAP versioning.(Recommended)”->“Next”

5.默认选项->“Finish”

6.Delphi会自动生成IMyData文件->保存

7.放入控件

ClientDataSet1

DataSource1

DBGrid1

8.DataSource1->DataSet:=ClientDataSet1

9.DBGrid1->DataSource:=DataSource1

客户端-实例代码：

unit Unit1;

interface

uses
