YAPoolman - Yet Another PoolMan

I'm getting several errors I cannot solve:

ERROR yapoolman.PoolManager - create pool ITCMD error:Object type net.sf.yapoolman.jdbc.JdbcConnectionWrapper not valid

And when trying to get a DataSource via JNDI:

java.lang.ClassCastException: net.sf.yapoolman.pool.ObjectPool

Here is my poolman.xml . Is there a way to create a DS via JNDI without an ObjectPool? Please help.
