我部署我的第7 tomcat的web應用到我的生產服務器,我有麻煩......類型不匹配:不能從ArrayList中<?>轉換爲ArrayList的<String>在Tomcat的7

的Web應用程序完美的作品上我的開發機器在Eclicpse Luna內部安裝了tomcat 7。 但是,當我試圖在生產服務器上運行(Ubuntu的12.04 + Tomcat的7 +的OpenJDK-7的JRE,無頭),login.jsp頁面給了我很多的編譯錯誤的:

org.apache.jasper.JasperException: Unable to compile class for JSP:

我猜我失去了我的生產機器或在配置文件中的東西...

ArrayList whiteList = new ArrayList ? – xcoder 2015-03-25 09:49:02

以及它可能是,但爲什麼相同的編譯在我的本地tomcat,而不是在Ubuntu的Tomcat? – lviggiani 2015-03-25 09:52:07

是的...這是問題(對我來說很遺憾)...仍然在想爲什麼它會在我的本地機器上編譯。 – lviggiani 2015-03-25 09:55:49

的問題可以通過用

ArrayList<String> whiteList = new ArrayList<String>(Arrays.asList("login.jsp")); 
更換

ArrayList<String> whiteList = new ArrayList<>(Arrays.asList("login.jsp")); 

解決

關於爲什麼它在本地運行,但不在'Live'中,可能您正在使用不同版本的jar(例如, servlet的api.jar文件)?
