Hi Kurt, Thanks again for the responses. JAX-WS interceptor is seems possible. (I didn't do it with the real scenario, but a PoC without juddi and my environment).
There can be occasions where people will add services to uddi registry without going through jax-ws calls. AFAIK we can use java APIs to do so. In that sense JAX-WS will not work for my case. So for JPA intercepting I added an Entiry Listener annotation( @EntityListeners(MyProjectEntityListener.class) to org.apache.juddi.model.BusinessEntity class in juddi. And I am getting this. Any idea why this occurs. org.apache.openjpa.persistence.PersistenceException: sun.reflect.annotation.TypeNotPresentExceptionProxy at org.apache.openjpa.kernel.AbstractBrokerFactory.newBroker(AbstractBrokerFactory.java:218) at org.apache.openjpa.kernel.DelegatingBrokerFactory.newBroker(DelegatingBrokerFactory.java:156) at org.apache.openjpa.persistence.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:227) at org.apache.openjpa.persistence.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:154) at org.apache.openjpa.persistence.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:60) at org.apache.juddi.config.PersistenceManager.getEntityManager(PersistenceManager.java:45) at org.apache.juddi.config.AppConfig.getPersistentConfiguration(AppConfig.java:109) at org.apache.juddi.config.AppConfig.loadConfiguration(AppConfig.java:95) at org.apache.juddi.config.AppConfig.<init>(AppConfig.java:62) at org.apache.juddi.config.AppConfig.getInstance(AppConfig.java:183) at org.apache.juddi.config.AppConfig.getConfiguration(AppConfig.java:205) at org.apache.juddi.Registry.start(Registry.java:55) On Thu, Apr 25, 2013 at 10:43 PM, Alex O'Ree <[email protected]> wrote: > I concur, a web service handler aka interceptor is your best bet. > Hi Alex, Can you please explain a bit more detail how to achieve this through web service handler ? > > On Thu, Apr 25, 2013 at 11:36 AM, Subash Chaturanga <[email protected]> > wrote: > > Hi Kurt, > > Thank you for the detailed description of the solution and links .I will > go > > through this and will update the thread once done.
