(1)..\tomcat-5.5.27\conf\Catalina\localhost\ROOT.XML中添加了如下一段:
<Resource
name="jdbc/LiferayPool"
auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:demo2"
username="portal"
password="portal"
maxActive="20"
/>

(2)..\tomcat-5.5.27\webapps\ROOT\WEB-INF\classes目录下新增portal-ext.properties
jdbc.default.jndi.name=jdbc/LiferayPool
hibernate.dialect=org.hibernate.dialect.Oracle10gDialect

(3)oracle驱动包ojdbc14.jar放在tomcat-5.5.27\common\lib\ext目录下.

完成这三步后启动tomcat,报错如下:

请问, 为什么会报错呢?

解决了吗？我也遇到这个问题，交流一下。

这个问题我也遇见过，解决了没？
我记得portal-ext.properties 是放在webapps\ROOT\WEB-INF目录下的，我的这个文件中只有一句话jdbc.default.jndi.name=jdbc/LiferayPool，至于使用方言那句话没有写，在启动时，它会读取portal-impl.jar中的portal.properties的数据库连接，如果是使用oracle，自动就会用oracle方言。

怀疑是建表的语句有问题！
这应该是第一次启动在数据库中建立对象吧！
