Ugh..this is quite frustating...8 full days already. I have to come up with a SSO-->LDAP-->JSF/Ajax-->SEAM-->ESB-->EJB-->JPA-->Database stack which includes jBPM + Drools by end of January.
Ok..getting back to the real world..at least the server side is running OK and the schema creation of the BIDDER table is working. It's only the client side that appears to be giving me problems. My plan is to get this Java Application client working and successfully inserting records and then change it into a session bean with @Session and then work on the JSF/SEAM UI front-end. Ok...given that the server side is working..I'm now just tweaking and playing around with various combinations within the client application code. I know that I don't have to create an entity manager in code because this annotated portion of code should inject me an entity manager binded to my persistent unit, BiddingTest : | @PersistenceContext(unitName="BiddingTest") | private static EntityManager em; | True enough, I commented the code creating the EntityManagerFactory and the app still runs with no error. I've gotten rid of the 'Unable to find datasource' error. Last time I did my EJB 2.1, I also had initial hiccup problems but putting in some properties code solved my problem. Here's my new BidClient.java :- | My jndi.properties file for BidClient.java is in the main folder of the client module as follows :- | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory | java.naming.provider.url=jnp://localhost:1099 | java.naming.factory.url.pkgs=org.jboss.naming.client | j2ee.clientName=BiddingClient | My application.xml file : | <?xml version="1.0" encoding="UTF-8"?> | | <application xmlns="http://java.sun.com/xml/ns/j2ee";
