burferd Wrote: I just downloaded the latest version of Jasper Reports and iReport and am attempting to create a new database connection to my SQL Server database. I am using this driver: sqljdbc4.jar and added the driver to the Databases->Drivers section in the Services window. I then attempted to create a new database connection using the connection information that works in my application. In the New Connection dialog, I tried both the Field Entry and Direct URL Entry methods. In both cases, when I fill out the connection information and push OK, the dialog greys out with only the Cancel and Help buttons active. I suspect it is attempting to create the connection, but apparently never does. The database is active and I can connect to it with both my application and the SWL Server Management Studio using the information I entered for the connection in iReport. Is there a problem with creating SQL Server database connections in iReport 4.5.0? Any suggestions on how I can create the database connection? Should I back off to an older version of iReport? Thanks i think you were not add the jar file in to classpath of ireport, right? should add it. or you can try use jtds-1.2.5.jar for SQL server connection.
