hibernate.hbm2ddl.auto was something I was certainly looking for in the
persistence.xml file...interesting that it is commented out.
Is there any chance that you may be deploying an old version of the jar -
where those lines are not commented out? (I know, this is a stretch, since
you're deploying it on other servers)
The other app servers you deploy this to, and it doesn't drop create - are
they glassfish? What version? What version of hibernate are you using?
I'm disinclined to say the problem may be with MySQL config..because MySQL
doesn't care/know anything about the DDL generation files. I believe more
likely it has something to do with the JPA library (hibernate) or perhaps
the way GlassFish hands off config values to Hibernate...although I believe
this is decoupled - the only the GF "knows" about is data source info (ie
connection info, pooling info, etc) - and that is defined in
sun-resources.xml.
