Im trying to update two MySQL databases (MySQL version 5.0.20) inside a single UserTransaction in Hibernate.
My Java Code:
Code:
tx.begin();
sf.getCurrentSession().save(ctmr);
sf2.getCurrentSession().save(fts);
tx.commit();
I have two separate hibernate configuration files for each session factory (sf and sf2). I created a JDBC resource and JDBC Connection Pool for each database in Sun Java System Application Server Admin Console (both of these ping successfully). I connect to these using the following code in my configuration files:
hibernate1.cfg.xml:Code:
<property name="connection.datasource">jdbc/__MySQLPool</property>
hibernate2.cfg.xml:Code:
<property name="connection.datasource">jdbc/__MySQLPool2</property>>
However when I run my java code I get the following exception:
Code:

I cant seem to find the problem because if I only update one database in my UserTransaction then the code works perfectly. Its only when I try updating two different databases inside the one UserTransaction that I get this problem.
I have to update both the databases in the one transaction - using two separate transactions is not an option.
If anyone can provide help on the matter that would be much appreciated.
