java - 失败 - 上下文路径/MyProject 中的应用程序无法启动(JndiException 和 NameNotFoundException)

Question

我正在尝试在 Tomcat 7 上部署我的项目。我包括

在 tomcat/config/context.xml 中:

<ResourceLink name="jdbc/MyProjectDS"
             global="jdbc/MyProjectDS"
              type="javax.sql.DataSource" />

和

在 tomcat/config/server.xml:

<Resource name="jdbc/MyProjectDS" auth="Container"
    type="javax.sql.DataSource"
    maxActive="100" maxIdle="5" maxWait="30000"
    username="username" password="password"
    driverClassName="com.mysql.jdbc.Driver"
    testOnBorrow="true"
    validationQuery="Select 1"
    url="jdbc:mysql://10.15.101.73:3306/myproject?autoReconnect=true"/>

但它返回异常如下:

在 myproject/hibernate.cfg.xml 中，我有以下代码:

    </session-factory>

</hibernate-configuration>

在 persistence.xml 中:

        </properties>
    </persistence-unit>    
</persistence>

我不知道为什么会出现这些异常，因为这是我第一次在 tomcat 服务器上部署项目。我试图用谷歌搜索解决方案，但没有一个能解决我的问题。我希望有人能指导我。提前致谢。

问题已解决

查了catalina.log发现异常是因为icu4j.jar文件版本太旧。只需将其替换为最新版本即可。

获得知识:Catalina.log 确实输出异常。

谢谢。
