Spring Application Context問題-數據源Bean創建

Question

我的這個webapp在我的本地碼頭服務器上運行良好。 我正在Jelastic上對其進行測試，因此可以在部署到生產服務器之前解決任何問題。

問題是，由於配置錯誤導致我無法啟動應用程序，因此無法解決，您能幫幫我嗎？

該問題的完整堆棧跟蹤為：

似乎是/WEB-INF/applicationContext.xml的問題，對不對？ 讓我們來看看。

/WEB-INF/applicationContext.xml

<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

<bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate">

<context:component-scan base-package="com.viktortech.automaton.rest" />

</beans>

那么，這個JNDI jdbc / appDB是什么，它在哪里定義以及如何定義？ 立即在/WEB-INF/jetty-env.xml文件中

<Configure class="org.mortbay.jetty.webapp.WebAppContext">

    <New id="viktor" class="org.mortbay.jetty.plus.naming.Resource">
        <Arg>jdbc/appDB</Arg>
        <Arg>
            <New class="org.springframework.jdbc.datasource.DriverManagerDataSource">
                <Set name="driverClassName">com.mysql.jdbc.Driver</Set>
                <Set name="url">jdbc:mysql://workingDBserver/database</Set>
                <Set name="username">******</Set>
                <Set name="password">******</Set>
            </New>
        </Arg>
   </New>
</Configure>

就是這樣了。 就像我說的那樣，它在localhost：8080上運行非常順利，但是當部署到遠程碼頭服務器（相同碼頭版本）時，它進入503狀態，然后產生上述錯誤。

請，請詢問您需要解決此問題的任何其他資源。 提前致謝。

看起來像類路徑上缺少的庫？

Root exception is java.lang.ClassNotFoundException: org.mortbay.naming.InitialContextFactory

您在使用Maven嗎？ 您如何將應用程序所需的所有jar加載到試圖運行此應用程序的JVM中的類路徑中？
