與tomcat的澤西錯誤WAR

我無法讓我的tomcat服務器與我的WAR文件一起工作。我使用的是澤西島1.14，它在eclipse中通過tomcat 6正常運行。但是當我將戰爭上傳到遠程tomcat 6服務器時，當我嘗試訪問該網站時，收到以下錯誤消息。與tomcat的澤西錯誤WAR

您的.war是在比新的JDK下編譯的，而不是遠程tomcat上提供的JRE。在遠程服務器上安裝匹配的JRE，或使用正確版本的JDK重新編譯項目。

這正是問題所在，我錯誤地使用1.7編譯而不是1.6。 – Chris

此行應該給你一箇中心思想：

java.lang.UnsupportedClassVersionError: com/shafer/server/server : 
Unsupported major.minor version 51.0 
(unable to load class com.shafer.server.server)

什麼是com.shafer.server.server？檢查您的庫的版本。

UnsupportedClassVersionError表示該類是使用比您在運行時使用的更新的Java編譯器編譯的。

我不知道爐旁的版本號，但是您應該使用JRE 6或更高版本來運行Tomcat。
