JDeveloper使用Toplink DB Provider发布Webservice

With JDeveloper 11gR2 you can now create database based web services using? JAX -WS Provider. The key differences between this and the already existing PL/SQL Web Services support is:

• Based on?JAX-WS Provider

In this entry I will explain the options of creating service based on? SQL? queries and Table? CRUD? operations.
SQL?Query based Service?
When you select this option,on 'Next' page it asks you for the DB Conn details. You can also choose if you want SOAP ?1.1 or 1.2 format. For this example,I will proceed with? ?1.1,the default option.

On the Next page,you can give the? query. The wizard support Bind Variables,so you can parametrize your queries. Give "?" as a input parameter you want to give at runtime,and the "Bind Variables" button will get enabled. Here you can specify the name and type of the variable.

At the next step,select the DB Connection and the table for which you want to generate the default set of operations:

Finish the Wizard. Now,run the service in Analyzer for a quick check.
See that all the basic operations are exposed:
