Teiid doesn't like when the jndi reference in the VDB is set to an empty space (example: connection-jndi-name=""). If I change it to " " (with space) its ok.

This was also verified in Designer when setting the jndi name.

The following warning is seen on the server:

08:04:19,487 WARN [org.teiid.RUNTIME] (MSC service thread 1-15) TEIID50099 Invalid JNDI name "" specified in VDB Yahoo 1: org.teiid.jboss.TeiidServiceNames$InvalidServiceNameException: TEIID50099 Invalid JNDI name "" specified in VDB Yahoo 1
at org.teiid.jboss.TeiidServiceNames.dsListenerServiceName(TeiidServiceNames.java:96)

but this will produce the following error message to the client when a query is executed:

SELECT * FROM "YahooStocksXML_View"."YahooStocksXMLView"
org.teiid.jdbc.TeiidSQLException: TEIID30504 YahooStocksXML_Source: org.jboss.as.naming.NamingContext is was not a ConnectionFactory implementation
