Hi
I'm trying to connect to SQL Server 2008 using JDBC. I downloaded the JDBC
from microsoft and there were two java files sqljdbc.jar and sqljdbc4.jar. I
imported sqljdbc4.jar into my application but when i get to conn =
DriverManager.getConnection(connString); i get the error below: the
connection string is
"jdbc:sqlserver://xxx.xxx.xxx.xxx:1433;encrypt=fasle;user=username;password=password;"
Can any one tell me what is going wrong? my code is below the error below. I
know that there are other ways to connect to a db and using JDBC isnt the
best but it the only suitable method for my application.
any help would be great and Thanks in advance.
