hi everybody,

i built a seamproject via new seam wizzard shipped with jboss tools.
i used default databseconnection with hsqldb.

now i want to change to postgresql and dont know how :-(

i tried to rewrite the myproj-ds.xml,hibernate-console.properties and persitence.xml, but starting my application results in following exception:

  | ...
  | 17:43:38,193 INFO  [InjectedDataSourceConnectionProvider] Using provided datasource
  | 17:43:38,265 INFO  [SettingsFactory] RDBMS: PostgreSQL, version: 8.2.6
  | 17:43:38,266 INFO  [SettingsFactory] JDBC driver: PostgreSQL Native Driver, version: PostgreSQL 8.3 JDBC3 with SSL (build 603)
  | 17:43:38,270 WARN  [ServiceController] Problem starting service persistence.units:ear=myproj-ear.ear,jar=myproj-ejb.jar,unitName=myproj

  | 	at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:720)
  | ...

is there any possibility to change the settings run at creationtime of the project?
when running new seamproject wizzard, i have to create a database connection, but where i can configure it later?

any ideas are welcome
