I'm not really familiar with dbcp, but my impression is that it is  
not jta-aware.  I'm also not that familiar with spring tx management  
but again I think that without a jta-aware pooling implementation  
hooked up to a jta (or jts) tm no container managed transactions will  
work.  In other words, I greatly doubt that what you are doing will  
work.  I'm happy to be proved wrong.
