About Creating J2EE Web Services

You can create web services from:

Java classes
the remote interface of EJBs
ADF Business Components service session bean wrapped as an EJB

You can also quickly create a J2EE web service from a Java class in the navigator. For more information, see Fast Creating J2EE Web Services.

It is important that Certain Java types are automatically mapped to XML types. If you want to use object types that are not automatically supported, you can write a custom serializer. For more information, see Java Classes and Web Services.

JDeveloper's web publishing wizards create the deployment files for you, so once you have created your web service the final step is to deploy it. For more information, see Deploying Web Services.
