I have problems using the pk-sql entity command to support auto-generated keys with Oracle sequence.
The JDBCPkSqlCreateCommand gets the correct new key, but fails during verification ->

2003-04-26 19:17:43,927 DEBUG [org.jboss.ejb.plugins.cmp.jdbc.JDBCPkSqlCreateCommand.Person] Executing SQL: SELECT PERSON_SEQ.NEXTVAL FROM DUAL

I am using the following components:
- JBOSS 3.2.0
- JRE 1.4.1
- Oracle 8.1.7
- JDBC Driver classes12.zip

Anyone has a solution for that problem?
