Hi All,
we are facing below issue while trying to login with single user on website. we are getting login page after we loggedin by using login credential, facing this issue

we used flex and Java with hibernate and SqlServer technologies. same war is working on dev server but its not working on prod server.

faultString = "java.lang.Exception : [EXCEPTION] IN module:LoginServiceImpl,
method:validateLogin, exception:java.lang.Exception: [EXCEPTION] IN module:TbMasUsersDaoImpl,
method:getUserByLoginParam, exceptionrg.hibernate.exception.GenericJDBCException: Cannot open connection"

is this problem with sql connections or firewall issue?
pls provide some ideas or solution for this issue?
