高分向高手请教JDBC连接Sybase的简单问题。

我刚接触WebSphere，正在开发一个WebSphere 4.0 + Sybase 11.9.2的程序。
我按照网上敲了一个例子程序，却出现如下结果：

[Jsp文件]
<%@ page contentType="text/html;charset=GB2312" %>
<%@ page import="java.sql.*" %>

<HTML>
<HEAD>
<TITLE> JSP测试SYBASE jconnect-5_2 JDBC数据库接口 </TITLE>
<META NAME="Generator" CONTENT="EditPlus2.11">
<META NAME="Author" CONTENT="naxin">

<BODY>
<center>JSP测试SYBASE jconnect-5_2 JDBC数据库接口</center>
<BR><BR>
<table border=3 align=center >
<%
Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
String url ="jdbc:sybase:Tds:localhost:2638";
Connection conn= DriverManager.getConnection(url, "dba","sql");
Statement stmt=conn.createStatement();
String sql="select emp_lname,dept_id,street,city,state from employee order by emp_lname";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {
out.print("<TR><TD>"+rs.getString("emp_lname")+"</TD>");
out.print("<TD>"+rs.getString("dept_id")+"</TD>");
out.print("<TD>"+rs.getString("street")+"</TD>");
out.print("<TD>"+rs.getString("city")+"</TD>");
out.print("<TD>"+rs.getString("state")+"</TD></TR>");
}
%>
</table>
<BR><HR>
<%out.print("数据库操作成功，恭喜你");%>
<%
rs.close();
stmt.close();
conn.close();
%>
</BODY>
</HTML>

我设置了ClassPath，也在工程中导入JConn2.jar；

请各位高手给与解答，谢谢！
