I have not connection.xml file, only DataControls.dcx When i do deploy on local server - WSdataControls running normaly, but jdbc connection for database loosing. Cannot finded, but this is other big problem of ADF with own themes on this forum.
Problem was: adf automaticly don't redeploy model to jar and get old jar. And if u change wsdl in model (dataControl.dcx) - adf don't update (redeploy jar) model.
Resolve of my problem: redeploy model in jar if needed and then do deploy (not run) on integrated WL.
