SQL Server URL for DBEdit2
As @a_horse_with_no_name points out, your connection string is incorrect.  The java jdbc driver needs to know the instance name ( it doesn't play well with the backslash notation ), which will be overridden if you're specifying the port ( 1433 is the default instance port - you might not have to specify the instance name at all if that's what you're trying to connect to ).

Try something along the lines of this instead for your connection string:


  jdbc:jtds:sqlserver://JT__428/j___test_db;instance=J__MS14
