問題描述
Adobe ColdFusion 9 Multi-Server 在 CF Admin 中沒有JVM 和 Java 設置"頁面，因此要向 CF 類路徑添加一些內容，對于給定實例，該實例必須使用備用 jvm 啟動.配置.
Adobe ColdFusion 9 Multi-Server doesn't have the "JVM and Java Settings" page in the CF Admin, so to add something to the CF classpath, for a given instance, that instance must be started with an alternate jvm.config.
從備用 jvm.config 開始我沒有問題.但是，我確實準確地知道如何以正確的方式編輯該文件.
I don't have a problem with starting with an alternate jvm.config. I do, however, have a problem knowing precisely how to edit that file in the proper way.
我的庫存 jvm.config 看起來像這樣(忽略換行符——它們不在實際文件中):
My stock jvm.config looks like this (ignore line breaks--they are not in the actual file):
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
我嘗試將類文件夾添加到類路徑中的一個比較成功的嘗試如下所示.(這里只是一對.)
One of my more successful* attempts at adding a folder of classes to the classpath looks like this. (Here are just a couple.)
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
*我說我更成功的嘗試之一"是因為實例確實啟動了，并且這些類在 CF 類路徑上[我可以使用 createObject() 實例化它們]，但是實例啟動并不干凈——有許多與 Flex 相關的錯誤:
*I say "one of my more successful attempts" because the instance does start, and those classes are on the CF classpath [I can instantiate them with createObject()], but the instance start is not clean--there are many Flex-related errors:

請注意，如果不將 {application.home}/servers/hud/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib 添加到 Dcoldfusion.classPath，服務器根本不會真正啟動.
Note that without adding {application.home}/servers/hud/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib to Dcoldfusion.classPath, as well, the server wouldn't really start at all.
那么，在 jvm.config 中干凈地向 ColdFusion 類路徑添加內容的神奇公式是什么?
So, what is the magic formula for cleanly adding something to the ColdFusion classpath in jvm.config?
推薦答案
來自 Christian Cantrell - 工程經理和傳播者，我給你 ColdFusion 類路徑權威指南(雖然有點過時了)
From Christian Cantrell - Engineering Manager and Evangelist, I give you The Definitive Guide to the ColdFusion Classpath (although it is a bit dated)
以下是我認為與您的設置相關的部分摘錄:
Here is an excerpt of the portion that I think relates to your setup:
J2EE 部署
將類或 jar 文件添加到類路徑的最簡單方法是簡單地將它們放到 lib 目錄中，它們會自動被拾取.該目錄位于 {cf_installation}/servers/lib.這些類文件將可供所有服務器使用.
The easiest way to add class or jar files to your class path is to simply drop them in the lib directory where they are automatically picked up. The directory is located at {cf_installation}/servers/lib. These class files will be available to all servers.
您還可以通過將類文件放到{cf_installation}/servers/default/cfmx/WEB-INF/lib"中，使它們僅對 ColdFusion 服務器可用.(請注意，將它們放入 {cf_installation}/servers/default/cfmx/WEB-INF/cfusion/lib 將不起作用.)
You can also make your class files available only to the ColdFusion server by dropping them in "{cf_installation}/servers/default/cfmx/WEB-INF/lib". (Note that putting them in {cf_installation}/servers/default/cfmx/WEB-INF/cfusion/lib will NOT work.)
您可以將它們放在任何 Java 擴展目錄中.要查找 Java 擴展目錄列表，請打開 ColdFusion 管理員并單擊系統信息".在底部，您將看到一個名為Java Ext Dirs"的系統屬性.您可以將 jar 和 class 文件放在任何這些目錄中，以讓 ColdFusion 服務器獲取它們.
You can drop them in any of the Java extension directories. To find a list of the Java extension directories, open the ColdFusion administrator and click on "System Information". Toward the bottom, you will see a system property called "Java Ext Dirs". You can put jar and class files in any of those directories to have them picked up by the ColdFusion server.
另一種方法是通過 JRun 管理控制臺添加類.打開控制臺，在默認服務器下，單擊設置，然后將您的類添加到類路徑列表中.(注意您也可以點擊默認服務器下的ColdFusion MX 應用程序"，然后點擊設置進行相同的更改.)
Another way to do it is to add classes through the JRun Management Console. Open up the console, and under the default server, click on settings, then add your classes to the class path list. (Note you can also click on "ColdFusion MX application" under the default server, then click on settings to make the same changes.)
最后，再一次，您可以自己編輯 jvm.config 文件，不過，我還是建議您堅持使用上述方法之一.
And finally, once again, you can edit the jvm.config file yourself, however again, I recommend you stick to using one of the methods above.
以下評論的更新
編輯 jvm.config 文件時(選項 5)，嘗試將目錄路徑添加到 jvm.config 文件中的 java.class.path= 行(在底部).不像您在發布的示例中所做的那樣在 java.args= 中.
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.
