请求帮忙！
在用weblogic连接池访问数据库时出现错误
程序如下：
import javax.naming.*;
import javax.naming.NamingException;
import java.sql.*;
import javax.sql.DataSource;
class pool
{
public static void main(String args[])
{
DataSource myds=null;
try
{
InitialContext myct=new InitialContext();
myds=(javax.sql.DataSource)myct.lookup("oraclepoolds");
System.out.println("ads");
Connection conn=myds.getConnection();
Statement myst=conn.createStatement();
ResultSet rs=myst.executeQuery("select * from emp");
System.out.println("ads");
while(rs.next())
{
System.out.println(rs.getString("EMANE"));
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
出错信息如下：
javax.naming.NoInitialContextException: Need to specify class name in environmen

Hashtable ht = new Hashtable();
ht.put(ctx.PROVIDER_URL, "t3://ip:port")
ht.put(ctx.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
ctx = new InitialContext(ht);Top
