hi all,
I have this error on my web application that i use jboss to add a work flow module api in it.This error is lunched only on oracle9i data base,on hsql and sqlserver it work. I am using tomcat 5.0.28 and jbpm3.1.4 and my test are on several database.
the exception is a hibernate exception i had got it when i used the hbm2ddl.auto property to create the data base schema.
Thank you for any help.
this is the exception:
