Hibernate version: 3

Mapping documents: I think the xml mappings seem to work fine when I use hibernate 2.

Here is the code between sessionFactory.openSession() and session.close():

public static Session currentSession() throws HibernateException {
Session s = (Session)session.get();
//Open a new session, if this thread has no session yet.
if(s == null) {
s = sessionFactory.openSession();
session.set(s);
}
return s;
}

public static void closeSession() throws HibernateException {
Session s = (Session)session.get();
session.set(null);
if(s != null) {
s.close();
}
}


Here is the full stack trace of the exception:

Exception in thread "main"


Database: Oracle 10g

The generated SQL (show_sql=true): The flag is set to true for show_sql in the xml hibernate.cfg.xml file. I get the error before the generated SQL shows up.

I am not using a log4j logging mechanism right now for logs.

It seems to work fine when I am using hibernate 2, but doesn't seem to work when using hibernate 3. I get the above exception. I copied all the hibernate3/lib libraries to my project's/WEB-INF/lib directory. Any suggestions and thoughts would be appreciated.

you still ahev the wrong asm version somewhere.
Please use the latest hibernate version with external asm jars

Emmanuel,

I am using the asm jars that came with hibernate 3. Do you know if they are not up to date? Do you know where I can download the latest versions of asjm jars?

Thanks.

Nirakar

Which cglib jar are you using? Some cglib jars actually bundle the asm classes directly.

Steve,

I am using cglib-2.1 and cglib-full-2.0.2.

Nirakar

Do you really need me to go on?

Steve,

What I did was I upgraded from hibernate version 3.0.3 (hibernate-3.0.3) to
hibernate version 3.0.5(hibernate-3.0.5). After that I copied all the hibernate3/lib jar files to my project's WEB-INF/lib directory and it started to work fine after that. I have been able to insert, update and get data from the database through hibernate 3.0.5 version. I will be testing it more thoroughly.

I am not sure though what is wrong with the hibernate-3.0.3 version. If someone knows what could be wrong with hibernate-3.0.3 version, then please let other people know here on this forum.

Thanks for your replies.
