Seam alters my DataBase on start up.

[jorgwel]

Hi guys! I really hope you can help me.

I have a problem using Seam 2.2FInal and seam-gen.

I had to make some modifications on my database last week, so I ran again seam-gen to update my application.

After running seam-gen, everything works fine, the problem comes when I start again my application on my jboss server, every column or table I erased from it are again there !!!, I don't know what's happening. I actually can see that seam has added some constraints that I did't put there :S

Some parameters on the properties file that seam-gen uses:

database.drop=n
database.exists=y

Seam is cool.

Solved.

I just had to change:

<property name="hibernate.hbm2ddl.auto" value="update"/>

to

<property name="hibernate.hbm2ddl.auto" value="validate"/>

in the different persistence.xml that come with the application generated by seam-gen. So my problem was with JPA and not with seam-gen.
