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