按照Tapestry指南搭建好了环境，也按照它的步骤编出了第一个Tapestry示例MyTapestry4。打开浏览器输入http://127.0.0.1:8080/Mytapestry4/app，正想有一点成就感的时候，不料结果却是这样:

十分感谢，确实是DOCTYPE里面两个字母没有大写的原因。不过还是没有调试成功，又有了新问题，请版竹再帮忙看一下吧。

呵呵，这个也解决了，原来tapestryforums上很多老外也有同样的问题，检查了一下支持包发现有三个下载错了，重新搜索下载下来，果然运行成功了。
“Tapestry项目搭建成功！”，真高兴呀！ 同时不忘感谢班竹哈，这里不错。。 |
