第6行错初始化的类全名不是你那个

Answer 2

java.lang.ClassNotFoundException: oracle.jdbc.Driver 
找不到这个类，楼主是不是哪里写错了、或者如二楼所说根本没有导入这个包！

Answer 3

驱动类名不正确好像URL也不正确

Answer 4

Class.forName("oracle.jdbc.Driver"); oracle.jdbc.Driver 换 oracle.jdbc.driver.OracleDriver 

Answer 5

ojdbc5.jar这个包放到了lib下没？

Answer 6

没有把oracle数据库 的驱动包放到工程目录下

Answer 7

 java.lang.ClassNotFoundException: oracle.jdbc.Driver oracle.jdbc.Driver  类不能被发现 。 楼主看看是不是包
我记得oralce驱动类好像是oracle.jdbc.driver.OracleDriver
楼组看看

Answer 8

tomcat\webapps\docs 下面的JNDI DATASOURCE 有各个数据库的详细配置 。。

Answer 9

给你个连接实例,自己参考
String sDBDriver = "oracle.jdbc.driver.OracleDriver";
String sConnStr = "jdbc:oracle:thin:@192.168.0.58:1521:ORCL";Connection conn = null;
ResultSet rs = null;
Statement stmt = null;
try
{
Class.forName(sDBDriver);
conn = DriverManager.getConnection(sConnStr,"veh_admin","oracle");
stmt = conn.createStatement();
//stmt.executeQuery("create table aaa(aaa int)");
//stmt.executeUpdate("insert into bbb values(456)");rs = stmt.executeQuery("select * from veh_xzqj");
while (rs.next()){
out.println("" + rs.getInt(1) + "");
out.println(":"+"<br>");
//out.println(" + rs.getString('answers') + ");
}
rs.close();}
catch(Exception e)
{
out.println(e);
} 

Answer 10

oracle.jdbc.driver.OracleDriver找不到驱动类
