使用Tynamo原型的TapestryFilter上的ClassNotFoundException

Question

我正在建立一个基于tynamo和Tapestry的tynamo-archetype新项目(让我们称它为分区)，我在运行jetty来测试它时遇到了一个问题。

我在tynamo目录上生成了带有mvn archetype:generate的id。

我唯一的定制是删除以下代码行……

<contextPath>/${project.artifactId}</contextPath>

我不知道问题出在哪里。这不是我的第一个Tapestry项目，但这是我第一次使用tynamo……

Answer 1

一切看起来都很好。我已经尝试了完全相同的配置(groupId、artifactId和package)，没有任何问题。唯一不同的是，我使用的是MacOSX，而您使用的是微软视窗。/ contextPath应该也不是问题。你能试试不同的jetty版本吗？也许使用与您已经使用的任何其他Tapestry项目相同的版本。您可以尝试使用Tapestry原型中使用的6.1.16版本：https://svn.apache.org/repos/asf/tapestry/tapestry5/trunk/quickstart/filtered/archetype-resources/pom.xml
