EJB Module Packaging

For EJB tier client components, the 

service ref

 element is defined in the

deployment descriptor of the 

ejb jar.xml

 file and the 

client jaxrpc mapping 

file.xml

 mapping file. The WSDL files are in a 

META INF/wsdl

 directory. The

service endpoint interface as well as generated class files are stored in the mod 

ule's root directory. 

The client developer should ensure that the 

resource ref

 definition in the

client deployment descriptor is correct and that the JAX RPC mapping file is

packaged in the correct module.

5.4.4.2

J2SE Clients

J2SE clients using stubs or dynamic proxies should package the service endpoint

interface with the application client, and they should be referenced by the class path

attribute of the package's manifest file. J2SE clients also must provide a JAX RPC

runtime. For example, a J2SE client is packaged along with its supporting classes or

with references to these classes. (See Figure 5.10.) The service endpoint interface as

well as the necessary generated files may be provided in a separate JAR file.
