为什么我无法从jar文件初始化组定义？

Question

我正在尝试从我们公司的jar文件创建bean来从数据库中检索数据。 我添加了

<context-param>
    <param-name>parentContextKey</param-name>
    <param-value>common.context</param-value>
</context-param>

到我的web.xml， 然后发生了一些错误

这是stacktrace：

我认为这是因为我遗漏了一个包含org / springframework / mail / javamail / JavaMailSenderImpl的jar文件 这个特定的文件是在springframework-context-support jar文件中，我确实拥有它并构建它的路径 现在我不知道为什么当我启动tomcat服务器时会发生这种情况。 这是我的web.xml
