推荐答案
对于使用Servlets API 2.5的用户,此论坛帖子可能会很有用(当您使用版本= 2.5的web.xml时也会出现此问题):
This forum post may be useful from someone who is using Servlets API 2.5(also problem when you are using web.xml with version=2.5):
https://community.jboss.org/message/647015#647015
您的具体问题可能是:
将Atmosphere 0.8.0-RC1与RichFaces 4.1.0.Final一起使用,因为Atmosphere 0.8.3具有与RC1不兼容的API!
Use Atmosphere 0.8.0-RC1 with RichFaces 4.1.0.Final, since Atmosphere 0.8.3 has incompatible API with RC1!
否则,我需要提供一些症状.
Otherwise I would need to provide some symptoms.
