試圖啓動一個戰爭文件 - 獲取錯誤 - 需要幫助理解catalina.out

Question

我提前道歉 - 爲什麼可能是一個常見的錯誤，但經過幾天試圖找出它......我認爲它看起來戰爭文件想要一個不同的java jdk ...但我現在已經嘗試了下面的這個版本以及openjdk 1.6和1.7。

Tomcat7在Wheezy上運行。這裏是我的JDK版本：

java version "1.8.0_05" 
Java(TM) SE Runtime Environment (build 1.8.0_05-b13) 
Java HotSpot(TM) Server VM (build 25.5-b02, mixed mode) 

這裏是我的$ JAVA_HOME：

/usr/local/java/jdk1.8.0_05 

這裏是我的 「catalina.out的」：

預先感謝您的時間和關注！

Answer 1

我可能已經解決了這個問題。

我安裝了openjdk 1.7。然後，我編輯了/etc/init.d/tomcat7並設置了JDK_DIRS =「/ usr/lib/jvm/java-1.7.0-openjdk-i386」。

Tomcat重新啓動成功，戰爭文件開始... kindof ...應用程序沒有完全工作，但這是現在的DEVs問題。它從Tomcat/Java POV出現 - 此問題已解決。

Answer 2

它看起來像您在App Server中以不同的JDK版本編譯，嘗試使用相同的jdk進行編譯。
