Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HBI-4
    Summary: Full feature support for connection pool DBCP
       Type: Patch

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate 1.2

   Assignee: 
   Reporter: Martin Schmidt

Description:
The following patch extends Hibernate 1.2.5 to support all features of the Apache DBCP connection pool. 

If a property is not specified, the default value from org.apache.commons.pool.impl.GenericObjectPool (connection pool) or org.apache.commons.pool.impl.GenericKeyedObjectPool (prepared statement cache) is taken.


Added configuration parameters to the hibernate.properties file:

# Connection pool

# Tests of connections
hibernate.dbcp.testOnBorrow
hibernate.dbcp.testOnReturn

# Eviction thread
hibernate.dbcp.timeBetweenEvictionRunsMillis
hibernate.dbcp.numTestsPerEvictionRun
hibernate.dbcp.minEvictableIdleTimeMillis
hibernate.dbcp.testWhileIdle

# -----------------------------------------------

# Prepared statement cache

# Tests of connections
hibernate.dbcp.ps.testOnBorrow
hibernate.dbcp.ps.testOnReturn

# Eviction thread
hibernate.dbcp.ps.timeBetweenEvictionRunsMillis
hibernate.dbcp.ps.numTestsPerEvictionRun
hibernate.dbcp.ps.minEvictableIdleTimeMillis
hibernate.dbcp.ps.testWhileIdle

--------------------------------------------------

Bug fixed:

Although it was possible to configure a validation query for the pool (in Hibernate 1.2.4), this query was never executed, because the DBCP properties "testOnBorrow" or "testOnReturn" were never enabled by the DBCPConnectionProvider.
