使用Tomcat7，Apache Wink和Mongo DB在WAR Deploy上記錄錯誤

Question

我在將應用程序部署到tomcat服務器時遇到問題。 每次部署它時都會得到以下跟蹤：

27-Oct-2013 17:02:34 org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /var/lib/tomcat7/webapps/JsonTest.war

服務器環境：

• Ubuntu 12.04.3 LTS 32位（我以后會把它變成64位......）
• Tomcat 7（僅從庫存安裝修改的東西是為經理[-gui]添加用戶）

• Java的

   $ java -version java version "1.6.0_27" OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1ubuntu0.12.04.2) OpenJDK Client VM (build 20.0-b12, mixed mode, sharing) 

應用背景：

我正在嘗試將這里概述的簡單“書籍REST應用程序”轉換為使用Mongo連接。 我有一種感覺，Mongo部分在這里無關緊要。 我也在使用Maven和Eclipse來部署/構建項目。

一些文件：

我不想用代碼污染帖子，所以如果你認為其他人會有用，請告訴我。

我感謝任何幫助。

Answer 1

java.io.IOException：無法鎖定％h / java％u.log

看起來Tomcat沒有文件系統權限來寫入日志文件。 %h變量是user.home系統屬性的值，該屬性通常是運行Tomcat進程的系統用戶的主目錄。 確保Tomcat具有該目錄的寫權限。

該directoy的位置可能會有所不同，但您可以通過以下方式以編程方式找到它：

System.getProperty("user.home")

您還可以通過為Tomcat啟動腳本提供-Duser.home=/your/path參數來修改默認值。
