Commons DBCP

[Dain Sundstrom]

In the OPENEJB-606, I've added a patch that converts the default data  
sources in OpenEJB to use Commons DBCP instead of the OpenEJB  
JdbcManagedConnection and SharedLocalConnectionManager.  With this  
patch applied we can use the configuration properties http:// 
jakarta.apache.org/commons/dbcp/configuration.html that most Tomcat  
users will be familiar with.

If we like DBCP, I think we should drop the JCA based JDBC code and  
throw our hat in with the commons team.

BTW, this patch is contingent on https://issues.apache.org/jira/ 
browse/DBCP-230 being applied which may take a day or so.
