Private static final String jdbcDriver = ".SQLServerDriver" Hello i am writing a similar code to connect to jdbc but i am getting the following exception:Įxception in thread “main” : javax/xml/bind/DatatypeConverter Drop a comment if something needs more explanation. ("Connection Failed! Check output console") ("SQL Connection to database established!")
