我使用的是weblogic8.1,配置了连接池和数据源,其中数据源的JNDI是jdbc/bn,在jsp中使用该数据源时出现问题,现将jsp程序和出现的异常贴在后面,请各位帮忙看一下,谢谢!!!!
jsp程序:
<%@ page contentType="text/html; charset=gb2312" %>
<%@ page import="javax.naming.Context"%>
<%@ page import="javax.sql.DataSource"%>
<%@ page import="javax.naming.InitialContext"%>
<%@ page import="java.sql.*"%>

<%
DataSource ds = null;
try{
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup("java:comp/env");
ds = (DataSource)envCtx.lookup("jdbc/bn");
if(ds != null){
out.println("已经获得datasource!");
out.println("<br>");
Connection con = ds.getConnection();
Statement stmt=con.createStatement();
ResultSet rst=stmt.executeQuery("select * from contact");
while(rst.next()){
out.println("<br>userName:" + rst.getString("userName") + "</br>");
}
}
else{
out.println("连接失败!");
}
}catch(Exception e){
e.printStackTrace();

}
%>

异常:
