Oops, the change is only in 2.5.

Re: [JBoss-user] Force create of table after manual drop?
Hmm, I'm interested to see that firebird/interbase is not the only rdbms with archaic syntax. In 2.4 (since june 16) you can specify not null constraints on your columns like this (per column) false Jaws will then create your tables with the not null columns so you can use primary keys. Code in CMPFieldMetaData and JDBCInitCommand. david jencks On 2001.07.28 14:40:57 -0400 David M.

Something is not right with your Driver or with JAWS (probably your setup). Any idea what causes it to believe that the primary key is null all of a sudden?

[JBoss-user] Force create of table after manual drop?
In JBoss 2.2.2, using MySQL, I had a sample application, and it had created a table. I manually dropped the table, now I'm trying to figure out how to get JBoss to figure out it needs to recreate the table. I've tried various things, like deleting the deployed jar from the "deploy" directory, and the unjarred directory in the "tmp" directory.
