1.我的tomcat5.0安装在D盘,在E盘建立了一个应用e:\testoracle里面有一个JSP的连接页面
2.在testoracle有个WEB-INF的文件夹,里面有lib\classes.jar
3.在D:\Tomcat\conf的server.xml配置了应用的路径
<Context path= "/a " docBase= "E:\testoracle " debug= "0 "/>
我只开了ORACLE的一个服务OracleServiceORACLE90,可以不?
我用的是ADSL的动态IP上网
index.jsp

出错信息:
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Io 异常: The Network Adapter could not establish the connection
请问大家是那里出错了?还需要配置那些地方才可以啊?
JDK1.5的CLASSPATH是C:\Program Files\Java\j2sdk1.5.0\lib\tools.jar;C:\Program Files\Java\j2sdk1.5.0\lib\dt.jar;
------解决方案--------------------
The Network Adapter could not establish the connection
把这个放到百度搜索下,你可以找到5000多的页面
------解决方案--------------------
oralce的jar包加到classpath了吗?
Class.forName( "oracle.jdbc.driver.OracleDriver ").newInstance(); 改为:
Class.forName( "oracle.jdbc.driver.OracleDriver "); (先试试)
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE); 改为:
Statement stmt=conn.createStatement(); (先试试)
------解决方案--------------------
与程序无关,可能是监听器没有启动,lz用你的用户名和密码登陆客户端管理工具(具体名称忘了)或者重新设置下oracle网络设置
