I am working with a web application that connects to a SQL Server database

  • 0

I am working with a web application that connects to a SQL Server database with this: 

jdbc.url=jdbc:jtds:sqlserver://127.0.0.1/MyDatabase
jdbc.username=sa
jdbc.password=password

I am relatively new to SQL Server, however I have successfully accessed a SQLEXPRESS instance through the SQL Server Management Studio.

I can see from the Security->Login folder there is a “sa” entry

However when I run the web application I am getting this error:

PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property
‘dataSource’ threw exception; nested exception is
org.apache.commons.dbcp.SQLNestedException: Cannot create
PoolableConnectionFactory (Network error IOException: Connection
refused: connect)

I seems that the user: “sa” is not authenticated to access the database?

If so, how can I use the SQL Server management studio to fix this?

    Make sure authentication mode is set to Mixed. It’s set to Windows authentication mode as default which disables sa account. See here: http://msdn.microsoft.com/en-us/library/ms143705%28v=sql.90%29.aspx

    Edit: as Jacob suggested, make sure you can connect via TCP/IP (I assume it’s used by the driver). To do so launch SQL Management Studio and in connection preferences set: Authentication - SQL Server authentication, login - sa, password - your password. Then click Options, connection properties and select tcp/ip as protocol. Check if you can login.
