java.sql.SQLException: No suitable driver found for jdbc:sqlserver [duplicate]

问题

I am working on a web application where I am creating MSSQLSERVER 2008 database dynamically.

But it's giving me

java.sql.SQLException: No suitable driver found for jdbc:sqlserver://localhost:1433;databaseName=master

My code is:

String dbName = "db1";
try {
    String url = "jdbc:sqlserver://localhost:1433;databaseName=master";
    Connection connection = DriverManager.getConnection(
                 url,
                 "sa",
                 "roshan14121987");

    Statement statement = connection.createStatement();
    String sqlquery = "CREATE Database \"" + dbName + "\"; ";
    statement.executeUpdate(sqlquery);
    statement.close();

    connection.close();

} catch(Exception e) {
    e.printStackTrace(); 
}

I have added sqljdbc4.jar in lib. I have tried it on both NetBeans (with GlassFish and Tomcat Server) and Eclipse IDE(Tomcat Server).

On the other hand I have tried this with simple desktop application, it's working fine on both IDEs. With sqljdbc4.jar added in lib.

回答1:

Before calling DriverManager.getConnection() you will have to load the SQLServer JDBC driver. You can do Class.forName("xxxx"); where xxxx is the appropriate driver class (fully qualified name with package prefix).

EDIT: Do this Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); to load the driver. Refer MSDN link for more.

回答2:

Is sqljdbc4.jar in your war file under WEB-INF/lib. This is the alternate location to $CATALINA_HOME/lib and recommended to keep your web application self-contained. Further, if you should ever need to change servers, you need only drop the war into your webapps directory.

You might also need a Class.forName([database class]).newInstance, but that isn't necessary using a JDBC 4.0 driver. Good luck and if you have further problems, do leave a comment.

回答3:

The error happen in the runtime on Tomcat Server,right? I think you need to make sure your sqljdbc4.jar deploy the in the Server.
