新手用jbuilder，很简单的问题。

我写了projector———》application——Designer页设计窗体，在窗体中放入一个JscrollPane 和JtextArea 及一个按钮。在一个按钮里写了：


void jToggleButton1_actionPerformed(ActionEvent e)
{
try
{
Class.forName("com.sybase.jdbc2.jdbc.SybDriver").newInstance();
String url=" jdbc:sybase:Tds:10.68.4.233:5000/test";
String user="sa";
String passwords="";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.CreatStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
Resulset rs=stmt.excuteQuery("select * from test");
String sql;
}
catch (Exception e1)
{}
}
}


却提示：
class Connection not found in class sy_demo.Frame
Variable DriverManager not found in class sy_demo.Frame
class Statement not found in class sy_demo.Frame
Variable Statement not found in class sy_demo.Frame
Variable RusutlSet not found in class sy_demo.Frame
