这是我连接到存储在不同服务器中的MS服务器的代码。它给出了一个名为“找不到类异常”的错误。我添加了sqljdbc4.jar和sqlserver.jar。请为我提供相同的解决方案。

final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
final String DB_URL = "jdbc:microsoft:sqlserver://10.5.5.205:0;databaseName=JavaUsecase";
final String USER = "sqljob";
final String PASS = "sqljob";
con = null;
s = null;
try{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
// System.out.println("Connecting to a selected database...");
con =java.sql.DriverManager.getConnection(DB_URL, USER, PASS);
//System.out.println("Connected database successfully...");
//STEP 4: Execute a query
//System.out.println("Inserting records into the table...");
s = con.createStatement();
String sql = "INSERT INTO account " +
"VALUES ("+username+","+Password+")";
s.executeUpdate(sql);
}
catch(Exception se){
//Handle errors for JDBC
se.printStackTrace();
}

我得到的错误是:-

最佳答案
确保 WebApps\yourProject\WEB-INF\lib 文件夹下有 sqljdbc4.jar 和 sqlserver.jar。如果您使用 Tomcat，那就是这样，否则就是在 TOMCAT_HOME\lib 文件夹中添加 jar。
