How to Write a stateful WS

• Step 1 Defining the interface in WSDL
• Step 2 Implementing the service in Java
• Step 3 Configuring the deployment in WSDD (and
  JNDI)
• Step 4 Create a GAR file with Ant
• Step 5 Deploy the service into a Web services
  container

17
Step 1 Defining the interface in WSDL

• MathService WSDL
• Namespace mappings

20
Write Java code

• MathNameSpaces
• MathService implements MathNamespaces
• MathResource implements Resource,
  ResourceIdentifier, ResourceProperties,
  MathNamespaces
• MathResourceHome extends ResourceHomeImpl

21
Step 3 Configuring the deployment in WSDD (and
JNDI)

• The WSDD deployment descriptor
• Tells the Web service container how it should
  publish our Web service
• The JNDI deploy file
• Locate resource homes.

22
Step 4 Create a GAR file with Ant

• Processing the WSDL file to add missing pieces
  (such as bindings)
• Creating the stub classes from the WSDL
• Compiling the stubs classes
• Compiling the service implementation
• Organize all the files into a very specific
  directory structure

Step 5 Deploy the service into a Web services
container

• ant \ -f share/globus_wsrf_common/build-packages.x
  ml \ deployGar \ -Dgar.nameltfull path of GAR
