Adobe ColdFusion 9 Multi-Server 在 CF Admin 中没有“JVM 和 Java 设置”页面，因此要向 CF 类路径添加一些内容，对于给定实例，该实例必须使用备用 jvm.config 启动。

从备用 jvm.config 开始我没有问题。但是，我确实无法准确地知道如何以正确的方式编辑该文件。

我的库存 jvm.config 看起来像这样（忽略换行符——它们不在实际文件中）：

java.args=-server -Xmx512m -Dcoldfusion.sessioncookie.httponly=true -Dsun.io.useCanonCaches=false -XX:MaxPermSize=192m -XX:+UseParallelGC -Xbatch -Djava.awt.headless=true
-Dcoldfusion.rootDir={application.home}/
-Djava.security.policy={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib/coldfusion.policy
-Djava.security.auth.policy={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib/neo_jaas.policy

我尝试将类文件夹添加到类路径中的一次比较成功的尝试如下所示。（这里只是一对。）

java.args=-server -Xmx512m -Dcoldfusion.sessioncookie.httponly=true -Dsun.io.useCanonCaches=false -XX:MaxPermSize=192m -XX:+UseParallelGC -Xbatch -Djava.awt.headless=true
-Dcoldfusion.rootDir={application.home}/
-Djava.security.policy={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib/coldfusion.policy
-Djava.security.auth.policy={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib/neo_jaas.policy
-Dcoldfusion.classPath={application.home}/servers/hud/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib,/var/www/apps/onecpd/GeoServices_sandbox

*我说“我更成功的尝试之一”是因为实例确实启动了，并且这些类在 CF 类路径上[我可以用 createObject() 实例化它们]，但是实例启动并不干净——有很多 Flex-相关错误：

请注意，如果不将 {application.home}/servers/hud/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib 添加到 Dcoldfusion.classPath，服务器根本不会真正启动。

那么，在 jvm.config 中干净地向 ColdFusion 类路径添加内容的神奇公式是什么？

来自 Christian Cantrell - 工程经理和传播者，我给你ColdFusion 类路径的权威指南（虽然它有点过时了）

以下是我认为与您的设置相关的部分摘录：

J2EE 部署

  1. 将类或 jar 文件添加到类路径的最简单方法是简单地将它们放在 lib 目录中，它们会自动被拾取。该目录位于 {cf_installation}/servers/lib。这些类文件将可供所有服务器使用。

  2. 您还可以通过将类文件放到“{cf_installation}/servers/default/cfmx/WEB-INF/lib”中，使您的类文件仅对 ColdFusion 服务器可用。（请注意，将它们放入 {cf_installation}/servers/default/cfmx/WEB-INF/cfusion/lib 将不起作用。）

  3. 您可以将它们放在任何 Java 扩展目录中。要查找 Java 扩展目录列表，请打开 ColdFusion 管理员并单击“系统信息”。在底部，您将看到一个名为“Java Ext Dirs”的系统属性。您可以将 jar 和 class 文件放在任何这些目录中，以让 ColdFusion 服务器获取它们。

  4. 另一种方法是通过 JRun 管理控制台添加类。打开控制台，在默认服务器下，单击设置，然后将您的类添加到类路径列表中。（注意您也可以点击默认服务器下的“ColdFusion MX 应用程序”，然后点击设置进行相同的更改。）

  5. 最后，再一次，您可以自己编辑 jvm.config 文件，但我还是建议您坚持使用上述方法之一。

从下面的评论更新

When editing the jvm.config file (option 5), try adding the directory path to the java.class.path= line in the jvm.config file (at the bottom). Not in the java.args= as you have done in the posted example.
