Hi, If I understand correctly "no-tx-datasource" isn't managed by JBossTS, but "local-tx-datasource" all connection is managed by JBossTS? If I would like to use spring to manage a JTA transaction, should I create datasource type "no-tx-datasource"? Currently, I use "local-tx-datasource", it has a problem about an enlistment, but it work fine when I use "no-tx-datasource". Does it has any side effict in the changing? Thanks.
