请尽量使用准确的文字描述作为标题

Original subject : 求助：

各位大虾，帮帮忙
我的部分代码如下：（数据库为：SQL）
String connectionURL="jdbc:odbc:sde";
  String name,zchar,tchar,mdchar,charxyd,char01,char02;
  int objid,id,shape;
   float x,y;

  try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
Connection con=DriverManager.getConnection(connectionURL);
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from 油井");

java控制台的提示信息为：
----------------------------------------------------
java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.jdbc.odbc)
  at java.security.AccessControlContext.checkPermission(Unknown Source)
  at java.security.AccessController.checkPermission(Unknown Source)
  at java.lang.SecurityManager.checkPermission(Unknown Source)

  at java.awt.Button.processEvent(Unknown Source)
  at java.awt.Component.dispatchEventImpl(Unknown Source)
  at java.awt.Component.dispatchEvent(Unknown Source)

  at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
  at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
  at java.awt.EventDispatchThread.run(Unknown Source)

请问这是什么问题？（我是刚接触java的新手，我做的是一个applet，编译通过了，但是执行的时候没有任何反应，就是控制台出现这样的提示！）
