Description

Tried using DBCPDataSourceFactory to map a Jetty 5.1.11 DataSource (as the default Cayenne PoolManager doesn't have connection validation feature), and ran into an NPE since it expected a Configuration object:

<New class="org.apache.cayenne.conf.DBCPDataSourceFactory">
   <Call name="getDataSource" id="dataSource">
       <Arg>etc/dbcp.properties</Arg>

    </Call>
  </New>

  
  <Call name="addService">
    <Arg>
      <New class="org.mortbay.jetty.plus.DefaultDataSourceService">
        <Set name="Name">DataSourceService</Set>
         <Call name="addDataSource">
             <Arg>jdbc/myDataSource</Arg>
             <Arg>
               <Ref id="dataSource"/>
             </Arg>
         </Call>
       </New>
     </Arg>
   </Call>
