8.9 BUILD WEB SERVICE CLIENTS TO CONSUME THE WEB SERVICE WEBSERVICEORACLESELECT To consume this Web Servic Visual Studio .NET barcode pdf417 e project, one can develop either a Windows-based or a Web-based Web Service client project. There is no signi cant difference between building a client project to consume a Web Service to access an SQL Server database and building a client project to consume a Web Service to access an Oracle database.

For example, you can use any client projects, such as either WinClientSQLSelect or WebClientSQLSelect, which we developed in the previous sections, to consume the Web Service project WebServiceOracleSelect with small modi cations. The main modi cation is to replace the Web Reference with a new Web Reference class, which is our newly developed Web Service WebServiceOracleSelect. Follow the modi cation steps below to complete these changes.

1. Remove the old Web reference from the Windows-based or Web-based client project. You need to rst delete the Web reference object, and then you can delete the Web Reference folder from the current project.

2. Add a new Web reference using the Add Web Reference dialog, run the desired Web Service project, copy the URL from that running Web Service. ASP.NET Web Services project, and paste it to t PDF-417 2d barcode for .NET he URL box in the Add Web Reference dialog box in the client project. 3.

Change the Web reference name for all data components used in the client project. 4. Change the names of the base class and derived class located in the Web reference.

5. Change the names of all Web methods located in the Web reference. Two completed client projects, WinClientOracleSelect, which is Windowsbased, and WebClientOracleSelect, which is Web-based, can be found at www.

. 8.10 BUILD AN ASP.NET WEB SERVICE PROJECT TO INSERT DATA INTO AN ORACLE DATABASE Basically, the procedure t barcode pdf417 for .NET o build an ASP.NET Web Service to insert data into the SQL Server database is very similar to the procedure to build an ASP.

NET Web Service to insert data into the Oracle database. The main differences are listed below: 1. 2.

3. 4. 5.

The connection string de ned in the Web con guration le Web.con g The namespace directories listed at the top of each Web Service page The stored procedures used by each Web Service page The protocol of the data query string used by each Web Service page The nominal names of dynamic parameters for the Parameters collection object. These ve distinguishing p oints exist between the procedures to build a Web Service to insert data into these two databases. Based on the discussion and analysis we made in Section 8.8 as well as the similarity between the SQL Server and Oracle databases, we will develop our Web Service projects to insert data into the Oracle database by modifying some existing Web Service projects.

In this section, we concentrate on the modi cations to the Web Service project WebServiceSQLInsert to make it into our new Web Service project WebServiceOracleInsert.. 8.10.1 Build a Web Service Project WebServiceOracleInsert In this section, we try to modify an existing Web Service project WebServiceSQLInsert to make it into our new Web Service project WebServiceOracleInsert and allow it to insert data into the Oracle database. Open the Windows Explorer and create a new folder 8 under the root directory if you have not already done so. Open Internet Explorer and browse to our desired source Web Service project WebServiceSQLInsert, which is located at www.

cambridge.org/9780521712354 in the folder DBProjects\ 8, and copy and paste it into our new folder, 8. Rename it WebServiceOracleInsert, and perform the following modi cations to this project:.
