You are only supposed to use the supplied database access tools from within Java plug-in nodes.

The Programming Guide says this

Quote:

Database access
Database access must be performed using the methods supplied for that purpose,
or by using the supplied processing nodes. Use of Java Database Connectivity
(JDBC) within plug-ins written in Java is not supported.
MbNode provides methods to create SQL statements that you can use to provide
database access under the transaction control of the broker.

On the other hand, it may be possible to write a java plug-in node that uses RMI or other such things to call out to a class running in another JVM that would allow you to access JDBC (for instance, calling an EJB).
