Weather Web Service Deployment Descriptor

3.8.2 Package Structure

Once the service implementation and deployment descriptors are completed, the fol 

lowing files should be packaged into the appropriate J2EE module:

  The WSDL file

  The service endpoint interface, including its implementation and dependent 

classes

  The JAX RPC mapping file, which specifies the package name containing the 

generated runtime classes and defines the namespace URI for the service. See 

Code Example 5.21 on page 242.

  The Web service deployment descriptor

The type of endpoint used for the service implementation determines the type

of the J2EE module to use.

E

The appropriate J2EE module for a service with a JAX RPC service endpoint 

is a WAR file. A service using an EJB service endpoint must be packaged in 

an EJB JAR file.

The package structure is as follows:

  WSDL files are located relative to the root of the module.

  The service interface, the service implementation classes, and the dependent 

classes are packaged just like any other J2EE component.

  The JAX RPC mapping file is located relative to the root of the module (typi 

cally in the same place as the module's deployment descriptor).
