[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - No Dialect mapping for JDBC type: 3

I'm getting this error in jboss 4.0.4RC1. I've seen a few things on the net about this issue and the solutions haven't solved my problem. The field that is giving me a problem is a sum(int) sql call in jdbc. Why would it return a decimal type anyway? I have written my own InformixDialect which hasn't helped yet. The returning values are as follows... 07:43:50,057 INFO [STDOUT] Type : 3 07:43:50,057 INFO [STDOUT] Size : 32 07:43:50,057 INFO [STDOUT] Precision : 32 07:43:50,057 INFO [STDOUT] Scale : 0 I added all the following column types just to try to cover my bases registerColumnType(Types.DECIMAL, "decimal"); registerColumnType(Types.DECIMAL, "number($p,$s)" ); registerColumnType(Types.DECIMAL, "numeric($p,$s)" ); registerColumnType(Types.DECIMAL, "decimal($p,$s)" ); I am still getting the same HibernateMappingException ("No Dialect mapping for JDBC type: 3") when I try to run the query. The query looks like this.. SELECT product_grp, sum(volume) where product_grp is a varchar and volume is an integer field. The database is informix 7.3. Any help or advice you could give would be greatly appreciated. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064573#...
