当我在tomcat中运行jsf项目时,它给出了如下错误。

答案 0 :(得分:2)
你告诉JSF使用Facelets作为视图技术,但你实际上使用JSP作为视图。这不会起作用。 Facelets是JSP的继承者,您应该选择使用其中一个。
假设您只想使用JSP,那么您应该删除来自<view-handler>
的{{1}},同时删除 {{1} }来自faces-config.xml
的参数,最好还删除来自javax.faces.DEFAULT_SUFFIX
的{{1}}声明。
或者,如果实际想要使用Facelets(推荐!),那么您需要根据Facelets developer guide配置Facelets并将JSP重写为XHTML。
