javascript连接数据库

[bluecrest]

第一次在tomcat下面运行脚本，报错如下，我不知道tomcat的pc上面要做什么设置才能用
Class.forName("net.sourceforge.jtds.jdbc.Driver").newInstance();
String url="jdbc:jtds:sqlserver://localhost:1433/yjssys;USER=sa;PASSWORD="; 来连接。

type Exception report

message An exception occurred processing JSP page /admin/../inc/conn.jsp at line 11

description The server encountered an internal error that prevented it from fulfilling this request.

看到除了亚马逊以外其他电商java/javascript的书籍都归在一类下面，我就很无语，乖乖回到亚马逊找书，其他的滚蛋吧，你让我在一群鸭子里面找几只鸡，还要看看哪个鸡最好 ，你想累死我们吗 ？甚至还有c/c++/vc/vc++/c#归为一类的，我只能说TMD. 正题 ： java 和 javascript 是几乎不相关的2门语言，那些电商不知道也就罢了，我们程序员可不能傻傻分不清楚啊。 javascript不能连接数据库。 over.
