假设在Web部署描述符中定义了一个上下文参数:
<context-param>
<param-name>initParam</param-name>
<param-value>initParamValue</param-value>
</context-param>
如何在web.xml本身中使用此参数,例如$ {initParam}还是什么?
<context-param>
<param-name>otherParam</param-name>
<param-value>(use initParam here)-otherParamValue</param-value>
</context-param>
