在Application.cfc中指定了java库

Question

我们创建了一个CFX客户标签和一个jar文件。 jar文件位于coldfusion服务器../WEB-INF/lib中。它成功处理多年。最近我们要升级到coldfusion11 linux。对于维护问题，系统管理员更喜欢将这些库文件从服务器WEB-INF / lib移出到应用程序本地目录。

以下是设置coldfusion 10的localpath的代码。

的Application.cfc

<cfcomponent>
    <cfscript>
        //this.name = hash( getCurrentTemplatePath() ); // unique app name
        this.javaSettings = {
            loadPaths: [
                "/opt/WebRoot-DEV/afsapps/tp-web-apps/payroll/process/java/lib"
            ],
            loadColdFusionClassPath: true,
            reloadOnChange: true,
            watchInterval: 100,
            watchExtensions = "jar,class"
        };
    </cfscript>

    <cffunction name="OnRequestStart" returnType="void">
         <cfargument name="targetPage" type="string" required="true" />

         <!--- Include Application.cfm --->
         <cfinclude template="Application.cfm" />
    </cffunction>
</cfcomponent>

但它不起作用，可以找到jar文件。我收到此错误消息： “错误消息是”在自定义标记数据库中找不到CFX自定义标记CFX_GenerateGarnishmentDocuments。您必须在使用之前将自定义标记添加到数据库。如果已将标记添加到数据库，请检查模板中标记的拼写，以确保它与数据库条目匹配。 “

我不确定我们是否可以将库文件移动到本地路径，这是否可行？如果是的话，该怎么办？

As the error message says - it is not enough to simply add the jar file. You must also register it in the ColdFusion Adminstrator under "Extensions->CFX Tags" ... A CFX tag is a specific jar file that implements a native API interface to CF so it can be used without java. it's a special thing.

Step 1 is to get your file INTO the class path. You can do this by putting it in the Lib director, or you can specify the path via the JVM args like so:

Restart CF and then register the CFX Tag in the CF Administrator like so:

---

---

The class name will be part of the documentation of the CFX tag. To use it you then call it as one thing - CFX_nameofthetag with attributes specified by the documentation.

---

CFX is basically a wrapper so that you can use something more complex and Java like in a simple primitive values in/out and get something coldfusiony back like a query or struct. It's designed to let you do ColdFusion without knowing a lot of Java. :)
