Come again? I am not sure what you are getting at. The API provides for setting only String based attributes. Further, I tried a simple test where I set an Integer (stringified of course) attribute and it never got set appropriately. After thinking about it, and kicking it around with other JBoss guys I have decided to add the DSXMetaData to the MetaDataRepository which now contains the ConnectorMetaData. The Repository exposes a simple MBean wrapper which allows me to establish a dependency between the old JCA MBeans to the repository iteself. As a result, the RARDeployment, JBossManagedConnectionPool etc can simply read their configuration from the respository at start.
