activiti-5.16.4 ---activiti-5.17 暂不支持servlet 2.5 ;tomcat6

刚想研究下 activiti 5.17，在tomcat6上部署activiti-explorer就报了如下错误：

百度找不到问题，最后google到这个网址：forums.activiti.org/content/activiti-explorer-5164-deployment-weblogic-java-6

看了主要意思是：

activiti-5.16.4 ---activiti-5.17 改为需要 Servlet 3.0 ；但是tomcat 6 是基于 servlet 2.5的。现在还没有补丁包出来。

所以只好使用5.16版本研究了。

Activiti Explorer 5.16.4 deployment to Weblogic Java 6

I ran into that very same problem. As far as i can see, this is because activity now requires Servlet 3.0. (Please see Stacktrace below) Tomcat 6 is Servlet 2.5 only. The new WebConfigurer-class uses ServletRegistration.Dynamic, which is not available in Servlet-API 2.5. I would have expected this to be clearly documented. Even worse: activity installation guide is referring to Tomcat 6 and requires quite a bit of changes for Tomcat 7. An installtion guide that can not possibly work really does give me second thougths about using activity.
