Cannot connect to sql server 2008 using JDBC

Question

I have tried all the methods to connect to the server.I am using sql server 2008 on mixed authentication mode.I can login via the sql server management studio using the sa login.But when I try accessing the same db from my java program I get the following error:

SQL Exception: com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'sa'. ClientConnectionId:191d94bb-a55e-47a0-bb9f-b84638313cf4

This is my connectionstring:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl= "jdbc:sqlserver://localhost;databaseName=Northwind;user=sa;password=sa;";

Answer 1

I have accessed my database in the same way. One of my problems were that I hadn't enabled the port and IP for the database. Check these options in SQL Server Configuration Manager. Hope this helps =)
