我有两台 linux 服务器，它们有一个运行在 2 个 WAR 文件中的两个 java 应用程序的 tomcat 7.0.42。我在 linux 上使用 JDK7u25，但其中一个仍然有一个指向 jdk1.4.2 的符号链接（我没有管理员权限，所以我无法更改它）。

具有正确符号链接 /usr/bin/java --> jdk 7 的 Linux 服务器工作正常。应用程序运行没有任何问题。

另一个具有 /usr/bin/java --> jdk1.4.2 的 Linux 服务器，但在 tomcat 中有一个 JAVA_HOME 设置为 jdk 7，（JAVA_HOME=//jdk_1.7.0.25/），在部署我的应用。我的应用需要 Forkjoin API（仅在 jdk 7 中可用）。

我注意到这两个服务器之间的唯一区别是符号链接。

我将工作的tomcat（目录+应用程序+ JDK）复制到不工作的服务器，并将JAVA_HOME设置为导入的工作JDK，但仍然无法工作......它不断向我抛出错误消息并且无法运行应用程序。

这是日志，尽管我认为它不够明确，无法理解我在做什么。

即使我已将 JAVA_HOME 设置到正确的位置，它是否可以来自 /usr/bin/java 下的 java？我找不到tomcat如何真正使用java ...

正如斯蒂芬所指出的，Tomcat 根据服务器配置使用多种不同的方式来确定正在使用的 java。

在大多数情况下，我会首先检查工作服务器是否存在 $JAVA_HOME，以及自定义 $PATH 设置。检查通常的嫌疑人：/etc/profile、/etc/profile.d/ 、.bash、.profile 等。

您甚至可能会发现 JAVA_HOME 既是在用户级别指定的，也是在初始化脚本中的服务级别指定的，如果您将它作为实际服务运行的话。

目前，您的问题中有许多变量没有答案：

1.) 您是否在两个位置以同一用户身份运行该进程？2.) 用户在两个位置的配置是否相同，具有相同的 PATH 优先级和 ENV 变量？3.) 初始化脚本是否相同？

通过向我们提供尽可能多的细节，我们可以提供更完整/彻底的回应。

Tomcat是否使用符号链接/usr/bin/java下的java？

这完全取决于您如何配置 Tomcat 以及如何启动它。

但好消息是，所有这些都发生在您可以轻松阅读的 shell 脚本中……如果有必要，还可以“破解”以找出java正在使用的命令。从启动命令或 init.d 脚本或其他任何内容开始，并跟踪它。

另外，请记住，很多这些东西都取决于您使用的 Linux 发行版，以及它们如何组合 Tomcat“包”。
