今天在写jsp连接到数据库sql的程式。
程式如下
<%}
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
out.println("有驱动程式24 ");
}
catch(ClassNotFoundException ce)
{
out.println("无驱动程式21232 ");
}
Connection h=null;
h = DriverManager.getConnection(""+ +
"jdbc:sqlserver://localhost:1433;user=****;password=****;database=A01");
%>
然而在DriverManager.getConnection 这个步骤遇到问题，我之前有用完全一样的
程式码，在以java写 jdbc并有成功连上。但不知为何在tomcat上的jsp档就出了问题。
差别之一可能是我先前的java语言是在eplice上撰写，而jsp档并不是
(但不知和这个有无相关。) 实际错误讯息如下:
HTTP Status 500 – Internal Server Error
