deploy


















Deployed as a HTTP servlet in any web or enterprise application module using 
OpenJPA as its JPA persistence provider. 


Completely metadata-driven and hence generic as opposed to specific to any 
application domain.
 

Introduces a URI syntax. Interprets the HTTP request as a JPA resource based on 
that syntax. The response is in XML or JSON format. 

Representational state for persistent instances is coherent. 
The response always contains the closure of the persistent instances. 

      
Connects to the persistent unit of an application in the same module. Or
    instantiates its own persistence unit.








	
	
	Following WEB-INF/web.xml descriptor will enable JEST to
	operate on a persistence unit named ${persistence.unit}. Of course, JEST 
	servlet must be in the same module scope of the application that is using using 
	${persistence.unit} as its persistence unit.  
	

<servlet>
  <servlet-name>${servlet.name}</servlet-name>
  <servlet-class>org.apache.openjpa.persistence.jest.JESTServlet</servlet-class>
	<init-param>
	  <param-name>persistence.unit</param-name>
	  <param-value>${persistence.unit}</param-value>
	</init-param>
</servlet>
<servlet-mapping>
  <servlet-name>${servlet.name}</servlet-name>
  <url-pattern>/${servlet.name}/*</url-pattern>
</servlet-mapping>


	When an web application module named ${webapp.name} containing the above JEST servlet 
	in a servlet container runs on ${server.name} at port ${server.port}, then the JEST servlet
	can be accessed at 

	http://${server.name}:${server.port}/${webapp.name}/${servlet.name}/
