Seam-gen generate does not work properly

[rgoytacaz]

Hello Seam Users,

I'm having a couple problems with my Seam start up.

I did the ./seam generate to reverse my current postgres db, which contains 4 tables, first I though everything was okay, just a warning message, but when I imported the project into eclipse, I saw that none of my packages had any class.

This is the error that seam generate, got me.

[hibernate] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering)
[hibernate] 1. task: hbm2java (Generates a set of .java files)
[hibernate] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
[hibernate] log4j:WARN Please initialize the log4j system properly.
[javaformatter] Java formatting of 0 files completed. Skipped 0 file(s).

Any ideas?

Regards

are you using seam-gen with Eclipse? In that case check you have specified to include all tables from your schema with Seam Generate entities option wizard. Otherwise, no class is generated as no table is to be processed.
If you are using console seam-gen command please paste your project build.properties settings file to have a look.

I was having the same exact problem today. I was able to resolve it by editing the file

jboss-seam-2.2.0.GA/seam-gen/build.properties

and setting the value of the property:

hibernate.default_schema=

(i.e. remove anything after the equal sign).

I´m using version 2.1.2 but everything seems to be ok, check Core is the name of your database schema and is written with the correct case and that url connection is the proper one.

Looking at my build.properties...

I realize that Im using a jdbc4 driver and hibernate is using a jdbc3 driver.. this must be the case...

Whats the hibernate jdbc4 drivers name?

[rgoytacaz]

Yea, its the correct schema name.. :(

[rgoytacaz]

I thought the problem to be about the log4j.. appender error..

[rgoytacaz]

Any help??

[jamesjmp]

um, really strange. Try it with seam 2.1.x to make it sure it is not an issue related to seam 2.2.0.

There is a problem with your data source definition. I know you're using the default provided by seam setup, but that's incorrect, because this class does not exist in postgresql-8.4-701.jdbc4.jar. Try changing your configuration to:

hibernate.connection.dataSource_class=org.postgresql.ds.PGConnectionPoolDataSource
