I am creating following thing using jython script
1)jdbc provide
2) datasource
3)J2C authentication data
4)WebSphere variables for sql server 2008
but when i am testing the connectivity it give me following error "Login failed for user ''. ClientConnectionId:a433489c-e9be-4891-b584-c87b79004661 DSRA0010E: SQL State = S0001, Error Code = 18,456" [b].
Solution of that which i found is that i have to open websphere console screen and in that i have to modify J2C authentication data(e.g if i just modify any value in Description section) and save the data & then if i test datasource connectivity it works.So can any please tell me what i am missing in my jython script
