Question

我利用Eclipse Helios,试图启动一个基于共同基金的项目。

在创建了一个新的工作空间之后,我安装了网络工具-平台。所有使用帮助菜单中的“Install New 软件”的人都很好地工作。

为了开始为我的项目做准备,我利用这些 w子设立了一个新项目,我下载并安装了Tomcat 6.0e,操作时间,并将该项目与“JavaServer faces v1.2”项目混为一谈。

我制作了一个单一的索引。

对散射线的探索似乎正在奏效。在浏览器上打指数时,我有几次例外:

我采取的每一个步骤都是一个标准浮游-穿透器的过程。

为什么这似乎行不通?

如果能够帮助的话,我可以很容易地张贴屏幕或排泄物,尽管我没有在这里这样做,以避免问题过多。

用户在几天前张贴了他的回答是完全正确的(尽管该员额已被删除)。

It s necessary to add the jstl.jar-file to /WEB-INF/lib AND in eclipse, you need to add it to the build path

而且,我不明白,如果母体为/faces/*,即使实际上不需要这种双管齐下,但你可以把档案放在任何方面,例如/faces/index.jsp。

非常感谢
