我遇到了JSF 2和Tomcat 7.0.0不断出现的问题。当我设置Apache MyFaces 2.0.4(通过将所有jar放入我的WEB-INF/lib
文件夹中)时,Tomcat成功部署了我的WAR文件。
但是,当我以与MyFaces相同的方式设置JSF(Mojarra 2.1.0 - FCS)时,会发生以下异常(这会导致Tomcat失败)。

我已完成Google搜索,但没有有效的解决方案可以解决此问题。
我的web.xml是3.0版本(虽然这是不必要的,但我把它放在这里以防万一有人问)。
为什么这对Tomcat无效?
答案 0 :(得分:2)
这与JSF issue 1937有关,这是因为自2.1.0 beta 9以来在JSF impl中意外使用Glassfish特定代码引起的。但是它应该已经在2.1.0 FCS中修复了。我还没有在Tomcat 7上尝试过,但它适用于JBoss 6(它使用Tomcat 7的一个分支)。或者,您也可以使用最新的2.0,目前为2.0.4。它肯定适用于Tomcat 6/7。
更新:我可以在Tomcat 7.0.11上使用2.1.0 FCS重现这一点:

我会踢1937年的问题并抱怨说它还没有为Tomcat修复。与此同时,你必须使用Mojarra 2.0。
