ClassNotFoundException – com.microsoft.jdbc.sqlserver.SQLServerDriver

I have a web development project using local install of Tomcat 7. I am trying to connect to SQL Server 2012 using Microsoft’s driver for jdbc (sqljdbc41.jar).

The sqljdbc41.jar is in my application build path:

and I am exporting it. Furthermore, in the Tomcat application directory lib folder I have also placed a copy of sqljdbc41.jar.

There are no compile errors, but at runtime when I try to load the SQL Server driver I get the following:

ClassNotFoundException - com.microsoft.jdbc.sqlserver.SQLServerDriver

The exception is thrown in the following code block:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://"+server+":1433;databaseName="+database+";user=sa;password="+password+";";
con = (Connection) DriverManager.getConnection(connectionUrl);

I have seen many posts on this topic without resolution:

  1. java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver : Am I loading the right driver?
  2. https://social.msdn.microsoft.com/Forums/sqlserver/en-US/b425c201-9882-4a48-b049-4004f202b0c6/javalangclassnotfoundexception-commicrosoftsqlserverjdbcsqlserverdriver?forum=sqldataaccess
  3. Getting ClassNotFoundException on code: “Class.forName(“com.microsoft.sqlserver.jdbc.SqlServerDriver”);”

and many more.

Compiler level 1.7 and a JRE of 1.7 – According to documentation, I believe I am using the correct driver. This also states that the CLASSPATH must be set:

echo $CLASSPATH
/var/common/sqljdbc41.jar

Which it is. Furthermore:

java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM)
64-Bit Server VM (build 24.75-b04, mixed mode)

So, why am I still encountering this???

Update

I downloaded the sqljdbc41.jar from Microsoft again – just to be sure that somehow the first jar was not corrupt.

Following Mick Mnemonic’s link, I removed the jar from the Java Build path and put the newly downloaded jar into the WEB-INF/lib folder of the web application. I then restarted Eclipse and the Tomcat server and cleaned the Tomcat server, and the project.

Still getting the ClassNotFoundException.

Also, the Eclipse IDE can see the driver:
