在命令行上运行 java 时显示错误消息“java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver”

Question

I am trying to run the java program on command line but this message is shown:

java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver

Then I have searched a few hours and most solutions are about checking the

1. Java version,
2. importing the JDBC jar and
3. editing the classpath

For 1, I checked the java version I am using is 1.8

So for 2, I have downloaded the sqljdbc41.jar, put the jar into a lib folder, and run the command with:

java -cp C://Testing/lib/* -classpath . sampleJava

For 3, I have edited the classpath to C://Testing/lib/sqljdbc41.jar

Anyone knows do I miss something so that the same error message still shows?

Below is the sample program I run:

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.text.SimpleDateFormat;
import java.util.HashMap;
import java.util.Map;

public class sampleJava {
  int x = 5;

  public static void main(String[] args) {
    sampleJava myObj = new sampleJava();
    try {
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    } 
    catch (Exception e) {
            System.err.println("Got an exception! ");
            System.err.println(e.getMessage());
            System.err.println(e);
            System.out.println(e.toString());
            e.printStackTrace();
        }
    finally {           
                System.out.println("Done");
        }
    System.out.println(myObj.x);
  }
}

Answer 1

This should help

java -cp C:/Testing/lib/*; sampleJava

or

java -cp C:/Testing/lib/sqljdbc41.jar; sampleJava
