Diagnosis

Open confluence.cfg.xml from Confluence Home directory and check if the the database class is like the following.

<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:sqlserver://<server>:<port>/<database></property> 

Cause

The class and database url are wrongly declared, the parameters need to be changed from confluence.cfg.xml in Confluence home directory.

Resolution

The database class and url string need to be declared like the following (See: Database Setup for SQL Server)

Please change <server>, <port>, and <database> accordingly

<property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:jtds:sqlserver://<server>:<port>/<database></property>
