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
服务端-实例代码：
1 unit WebModuleUnit1;

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：
1 unit Unit1;
