RAD 链接数据库

[puhongchun]

我的java应用程序为



package com;

import java.sql.Connection;
import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;

public class conn {


public static void main(String[] args) throws Exception {

InitialContext initialContext = getInitialContext();

javax.sql.DataSource ds = (DataSource)initialContext.lookup("jdbc/msSql");

Connection cn = ds.getConnection("sa","uoon");

if(cn != null)
System.out.println ("Connection ok");


}
public static InitialContext getInitialContext() throws NamingException {
Hashtable env = new Hashtable();

env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL,"iiop://localhost:2809"); //iiop是协议

InitialContext context = new InitialContext(env);

return context;
}


}



web.xml代码为




<resource-ref id="ResourceRef_1242548482171">
<description>
</description>
<res-ref-name>WebSphere embedded ConnectJDBC for SQL Server DataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>



ibm-web-bnd.xmi代码为



<?xml version="1.0" encoding="UTF-8"?>
<webappbnd:WebAppBinding xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:webappbnd="webappbnd.xmi" xmi:id="WebAppBinding_1242542052640" virtualHostName="default_host">
<webapp href="WEB-INF/web.xml#WebApp_ID"/>
<resRefBindings xmi:id="ResourceRefBinding_1242548482171" jndiName="jdbc/msSql">
<bindingResourceRef href="WEB-INF/web.xml#ResourceRef_1242548482171"/>
</resRefBindings>
</webappbnd:WebAppBinding>


我在webShere6.1的服务器数据源test链接
成功 jndi名字为jdbc/msSql


可是依然报异常，死活链接数据库失败！
