Do WSAD and Eclipse with JDT have similar configuration?

No, that's not a mistake. This code was committed after release.
Currently FBConnectionPoolDataSource cannot be used as JavaBean, and
I'm still not finished with the classes. You can try to use Jakarta
DBCP, they also implement javax.sql.ConnectionPoolDataSource. Probably
code in CVS will never be in use due to maturity of DBCP.
