15. Re: looking for non-EJB SEAM example...
sammy8306 Apr 11, 2007 6:23 AM (in response to lindsayh)I see. Well, I guess this is not my lucky day... after changing the connection url to:
jdbc:hsqldb:hsql://localhost/blogjpa
I get the following exception:
(and yes, the DB is up and running, when it's not I get an error for not being able to open the socket. And, it's not empty, but the create-drop should take care of that)12:11:15,328 WARN [LocalTxDataSource] Throwable while attempting to get a new connection: null org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.sql.SQLException: Connection is broken: Transfer corrupted) at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.c reateManagedConnection(LocalManagedConnectionFactory.java:164) at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.cr eateConnectionEventListener(InternalManagedConnectionPool.java:519) at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.ge tConnection(InternalManagedConnectionPool.java:208) at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BaseP ool.getConnection(JBossManagedConnectionPool.java:529) at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManage dConnection(BaseConnectionManager2.java:412) at org.jboss.resource.connectionmanager.TxConnectionManager. ... et cetera
Could this be due to an incompatability between the hsqldb jars used by the microcontainer and the ones I use to start the database? Where do I find the jars used by Seam? -

christian.bauer Apr 11, 2007 6:28 AM (in response to lindsayh)I have no idea what hsqldb.jar(s) you deploy, so I can't help you with that. Maybe just a file search would help...

sammy8306 Apr 11, 2007 6:36 AM (in response to lindsayh)I found the hsqldb.jar in the lib/mc directory, missed it the first time around. Replaced it with 'my' hsqldb.jar and now it finally works. I'm still getting a nullpointer on the injected EntityManager, but I'll debug a bit more before asking about it :-)
Once again, thanks for your kind and patient answers. You guys are the best! -
18. Re: looking for non-EJB SEAM example...
lindsayh Apr 11, 2007 9:17 AM (in response to lindsayh)Ok, so back to my original post. I guess this doesn't have anything to do with EJBs. So here's what I i'd like to know now...
I have two Hibernate3 cfg.xml files (two dbs) and lots of hbm.xml mapping files. I'd like to use these with Seam in the 'best' way possible.
Can anyone advise what configuration I should use? i.e. do I need the microcontainer and a jboss-beans.xml? If so, do I also need the -ds.xml datasource file? And where do these go in Jboss? Both in the deploy dir? OK enough questions!
I fiddled with the seam-gen-erated project to get it working with Hibernate, and having read the reference guide (Chapter 21), I decided not to use the microcontainer (since I'll be using Jboss 4 anyway). Is this the right decision to make?
