You can create a web service from a project in the navigator. In this case, you have to specify the database connection and the package containing the program units you want to deploy as web services.
To create the PL/SQL web service from a project:
The files to implement the web service are added to the navigator. For more information about the generated files, see Generated Web Services Files.
Now that you have generated the deployment information for your PL/SQL web service, the final step is to deploy the files to OC4J. This is the same as deploying any other J2EE Web Application. For more information, see Deploying J2EE Web Services to OC4J.
