First of all, thanks Romain for recommending the following, and for that I will gladly start a new thread. :)
TomEE/OpenEJB and failover of datasources[1] which references [OpenEJB] Dynamic Datasource[2] but I found the following TomEE example: [TomEE] Dynamic Datasource Routing[3] So, before I begin, my questions are as follows: 1. I recognized that failover[1] says that the idea is to 'reuse' dynamic datasource. Does this mean that we should code openejb[2] or tomee[3] dynamic datasource, first, and then reference accordingly via failover[1]? 2. or failover[1] requires no coding on our part? only developer needs to setup the failover 'config'? 3. also, tomee[3] dynamic datasource routing recommends openejb.xml (instead of tomee.xml). can openejb.xml cofiguration be placed in tomee.xml, too, or not? 4. okay, never mind, I was abouto ask for some clarification about META-INF/org.router/service-jar.xml, but I 'found' service-jar.xml on trunk[4]. :) [1] http://rmannibucau.wordpress.com/2013/04/26/tomeeopenejb-and-failover-of-datasources/ [2] http://tomee.apache.org/dynamic-datasource.html [3] http://tomee.apache.org/examples-trunk/dynamic-datasource-routing/README.html [4] http://svn.apache.org/repos/asf/tomee/tomee/trunk/examples/dynamic-datasource-routing/src/main/resources/META-INF/org.router/service-jar.xml
