Re: [forge-dev] Fw: Re: Mojavelinux.com Feedback: seam-gen and cdi/weld

The persistence.xml just needs to be on the classpath at META-INF/persistence.xml as defined by the spec. (assuming you use jpaconfiguration) But how often will a persistence.xml actually have the database connection info ? if it is the persistence.xml used for deploying then it will contain the datasource name and nothing else aka. not enough info for hibernate tools nor hibernate it self to connect "outside" the server. This is why in hibernate tools (both ant and eclipse version) we allow you to specify a properties file to use that will override anything found in persistence.xml on the classpath/default hibernate configuration semantics. Until Forge it self gets a notion of database connection info I would suggest using this separate properties file for development connection info would be the simplest/easiest approach ? (we even have a "standard" name for it with default content to get the best non-invasive behavior) here is what seam 2 projects made by seamgen and/or jboss tools looks like: #File used by hibernate tools to override <datasource> and other container specific settings in persistence.xml hibernate.connection.password= hibernate.connection.username=sa hibernate.connection.driver_class=org.hsqldb.jdbcDriver hibernate.dialect=org.hibernate.dialect.HSQLDialect hibernate.connection.url=jdbc:hsqldb:. hibernate.connection.provider_class=org.hibernate.connection.DriverManagerConnectionProvider hibernate.datasource= hibernate.transaction.manager_lookup_class= The default (bad?) name is hibernate-console.properties. Notice, the last three elements would probably be better off being defaulted in forge plugin to ensure hibernate won't start doing any of its JEE integration code just because you have a peristence.xml with datasource and jta tx info in it. /max On Apr 15, 2011, at 18:55, brian wrote: > > hi L3 and john. > > I was thinking about the persistence.xml.
