上的Activiti的休息5.16.4我們得到以下錯誤，我們的舊的實例15.4正在啓動的啓動沒有問題：

我們使用Tomcat 6.0.39和JRE 1.7 .0_65-b32在我們的託管服務器上。

我們想念圖書館或有配置問題嗎？或者它與Spring 4有關？或者activiti 5.16與tomcat 6不兼容？

Answer 1

DispatcherType是在Servlet規範3.0中引入的，就我而言。 如果你看看這裏的Tomcat版本支持表：http://tomcat.apache.org/whichversion.html

你會看到Tomcat 6支持servlet spec 2.5，所以這很可能是你的類未找到錯誤的原因。

升級到Tomcat 7，我估計你會變成金色的。

乾杯， Greg
