If you are scanning your path for JAX-RS annotated resource beans, your beans will be registered in per-request mode. This means an instance will be created per HTTP request served. Generally, you will need information from your environment. If you are running within a servlet container using the WAR-file distribution, in 1.0.0.Beta-2 and lower, you can only use the JNDI lookups to obtain references to Java EE resources and configuration information. In this case, define your EE configuration (i.e. ejb-ref, env-entry, persistence-context-ref, etc...) within web.xml of the resteasy WAR file. Then within your code do jndi lookups in the java:comp namespace. For example:
web.xml
<ejb-ref> <ejb-ref-name>ejb/foo</ejb-ref-name> ... </ejb-ref>
resource code:
@Path("/") public class MyBean { public Object getSomethingFromJndi() { new InitialContext.lookup("java:comp/ejb/foo"); } ... }
You can also manually configure and register your beans through the Registry. To do this in a WAR-based deployment, you need to write a specific ServletContextListener to do this. Within the listener, you can obtain a reference to the registry as follows:
public class MyManualConfig implements ServletContextListener { public void contextInitialized(ServletContextEvent event) { Registry registry = (Registry) event.getServletContext().getAttribute(Registry.class.getName()); } ... }
