我有非常复杂的程序要运行。我不希望任何人深入分析，但也许有人有类似的问题或有诊断提示。应用程序正在使用 Apache Tomcat 启动。这些是我在浏览页面时看到的堆栈跟踪：
例外：

根本原因：

很难从我那里诊断出真正不起作用的东西 - 但我预计 Tomcat 方面会出现问题。指定的 Layout.jsp 文件路径似乎很好 - 但我不能说 Tomcat 是否看到该文件。如果我删除 Layout.jsp，我会看到同样的错误。另一方面，有一个名为 tiles-config-ext.xml 的文件，其中包含：
<definition name="BOMainWindow" template="/resources/layout/Layout.jsp">
<put-attribute name="body" value="something" />
<put-attribute name="leftMenu" value="true" />
<put-attribute name="rightBanner" value="something2" />
</definition>
当我将模板更改为 Layout2.jsp 并在适当的位置创建该文件时 - 我有不同的错误 - 响应 404。即使我从每个文件中删除“Layout.jsp”。
