Answer 1

jsp不能编译，FacesContext有没加进来

Answer 2

把服务器的tomcat和你机器的tomcat保持一致
还有jdk,jre也是

Answer 3

javax.faces
看是否存在
或者重新导入

Answer 4

把服务器的tomcat和你机器的tomcat保持一致 
还有jdk,jre也是 
同意这个
包的问题。

Answer 5

我把它再现出来了.但只出现了一次,是把包删掉后,再加进去出现的.
为什么为出现这种情况,像楼上说的,再现时javax.faces包是报错的.能告诉我是哪个包出了问题吗

Answer 6

同意把服务器的tomcat和你机器的tomcat保持一致 
还有jdk,jre也是 
 

Answer 7

有的jar包没拷进去。上面报的错你怎么不看啊？The import javax.faces cannot be resolved 翻译下大概就是你的这个类库无法解析，你看下这个类库是那个包里的就知道了。

Answer 8

谢谢各位帮忙!问题解决了说起来有点怪
我直接用MyEclipse发布(带JAR包)到tomcat就可以正常运行
昨天我为了节省空间,把JAR包单发的,客户那里再自行把JAR包拷进去就会报那样的错!!呵呵,不管怎么说解决了!!!
