我尝试运行此程序时遇到此异常.这是微软的一个例子.我已经通过项目属性将sqljdbc4.jar添加到netbeans中的类路径中,用于编译和运行.我还测试了可以通过使用下面的import语句找到该类 - 在编译期间没有错误,所以它必须找到jar.

是否与sqldbc4.jar引用的dll或某些sql dll有关？

这是确切的例外,下面是确切的代码,密码除外.

例外:

run:
java.sql.SQLException: No suitable driver found for jdbc:microsoft:sqlserver://localhost:1433;databaseName=HealthCareDatabase
Error Trace in getConnection() : No suitable driver found for jdbc:microsoft:sqlserver://localhost:1433;databaseName=HealthCareDatabase
