1.我用驱动private String driver = "com.mysql.jdbc.Driver";，但是老出现下列错误
Daemon System Thread [Finalizer] (Suspended (exception java.lang.NullPointerException))
sun.jdbc.odbc.JdbcOdbcDriver.finalize() line: not available
java.lang.ref.Finalizer.invokeFinalizeMethod(java.lang.Object) line: not available [native method]
java.lang.ref.Finalizer.runFinalizer() line: not available
java.lang.ref.Finalizer.access$100(java.lang.ref.Finalizer) line: not available
java.lang.ref.Finalizer$FinalizerThread.run() line: not available

2.还出现如下错误：

我的registerInfo.jsp如下：
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
