I found this in the DataSourceDeploymentMetaData at lines 337-351 I am thinking that the second properties setName() is using the wrong name. I don't think both properties are supposed to be using the same name, unless it is an either/or config property | if(getStaleConnectionCheckerClassName() != null) | { | property = new ManagedConnectionFactoryPropertyMetaData(); | property.setName("StaleConnectionCheckerClassName"); | property.setValue(getStaleConnectionCheckerClassName()); | properties.add(property); | } | | if(getURLSelectorStrategyClassName() != null) | { | property = new ManagedConnectionFactoryPropertyMetaData(); | property.setName("StaleConnectionCheckerClassName"); | property.setValue(getStaleConnectionCheckerClassName()); | properties.add(property); | } | Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123763#...
