User development, A new message was posted in the thread "How to create a XA aware connection factory": http://community.jboss.org/message/527605#527605 Author : Kreek Fred Profile : http://community.jboss.org/people/fredk Message: -------------------------------------------------------------- After spitting through the jboss sourcecode I solved the problem myself:   the property 'URLProperty' refers to a named property in the config-property XADataSourceProperties   So one should use the following lines in the connection factory: <config-property name="URLProperty" type="java.lang.String">$PROPNAME</config-property> <config-property name="XADataSourceProperties" type="java.lang.String">$PROPNAME=$CONNECTIONSTRING</config-property>   where the both $PROPNAME's should be the same and the $CONNECTIONSTRING should be the connection string   e.g.   <config-property name="URLProperty" type="java.lang.String">URL</config-property> <config-property name="XADataSourceProperties" type="java.lang.String">URL=jdbc:thin:@localhost:1521:XE</config-property> -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/527605#527605
