DataNode getDataSource()

["Watkins, Garry" <gw...@motleyrice.com>]

Andrus,

I have successfully gotten the EOModel to load from within WebObjects,
however, I am having a difficult time figuring out how to associate a data
source with the DataNode.

I am able to get all of the information from the eomodel to set up a
DataSourceInformation object.  If it is a standard JDBC connection, how do I
get Cayenne to use the DSI at run time to generate a connection?  I guess a
better question is, shouldn't the DataNode.getDataSource() method use the
dataSourceFactory and the DSI to create a dataSource at run time if the
dataSource is null?

Any guidance that you can give me would be appreciated.

Thanks
Garry

While DataNode stores 'dataSourceFactory' name for historical  
reasons, it never actually uses it. So you have to create and set a  
DataSource instance on your own.  
"org.objectstyle.cayenne.conn.PoolManager" is a convenience  
implementation that you can use.
