java - 使用 Tomcat7、Apache Wink 和 Mongo DB 在 WAR Deploy 上记录错误

Question

我在将应用程序部署到我的 tomcat 服务器时遇到问题。每次部署它时，我都会得到以下跟踪：

27-Oct-2013 17:02:34 org.apache.catalina.startup.HostConfig deployWAR

服务器上下文：

Ubuntu 12.04.3 LTS 32 位（稍后我会升级到 64..）
Tomcat 7（从库存安装修改的唯一内容是为管理器添加用户[-gui]）

爪哇

$ java -version

应用上下文：

我正在尝试将此处概述的简单“书籍 REST 应用程序”转换为使用 Mongo 连接。我觉得 Mongo 部分在这里无关紧要。我还使用 Maven 和 Eclipse 来部署/构建项目。

我不想用代码污染帖子，所以如果您认为其他人有用，请告诉我。

我很感激任何帮助。

java.io.IOException: 无法获得 %h/java%u.log 的锁定

It looks like Tomcat does not have filesystem permissions to write to the log file. The %h variable is the value of the user.home system property, which is usually the home directory of the system user running the Tomcat process. Make sure that Tomcat has write permissions to that directory.

The location of that directoy can vary, but you can find it programmatically with:

System.getProperty("user.home")

You can also modify the default value by providing the argument -Duser.home=/your/path to the Tomcat startup script.
