问题描述
尝试连接数据库时出现以下异常:
I'm getting the follwing exception while trying to connect to a database:
java.sql.SQLException: ORA-01005: null password given; logon denied

at com.alting.med.EventGenerator.exportData(EventGenerator.java:220)
at com.alting.med.Main.main(Main.java:252)
此处是用于获得连接的方法:
here the method used to get the connection:
private Connection getConnection(String url, String driverClass, String user, String password) throws ManagerDBException
{
try
{
Class.forName(driverClass);
} catch (ClassNotFoundException e) {
throw new ManagerDBException(e.getMessage());
}
try
{
this.connection = DriverManager.getConnection(url, user, password);
}
catch (SQLException e)
{
throw new ManagerDBException(e.getMessage());
}
return this.connection;
}
但是即使对参数(URL,密码..)进行了硬编码,我仍然会遇到异常.
But even when the params (url, password..) are hardcoded, I still get the exception.
您能告诉我如何解决此问题吗? 谢谢
Could you tell me how to fix this problem ? thanks
推荐答案
看来问题是从Java启动命令行链接到"-Djava.endorsed.dirs"参数的.
it appears the problem is linked to the "-Djava.endorsed.dirs" parameter from the java startup command line.
通过删除这一部分,一切顺利.
By removing this one, everything goes well.
