如何在Coldfusion中使用java文件 [英] How do you use java files in Coldfusion

问题描述

我需要导入一个java文件到coldfusion 8页例如。 ：

I need to import a java file into a coldfusion 8 page e.g. :

public class Hello 
{ 
    public String testJava() 
    { 
    return "Hello Java!!"; 
    } 
}

在Coldfusion中，我有以下代码：

In Coldfusion I have the following code:

<cfscript>
   helloWorld = CreateObject("java","Hello");
   helloTest = helloWorld.testJava();
</cfscript>

然后我收到错误

对象实例化异常。找不到类：Hello

Object Instantiation Exception. Class not found: Hello

在我的ColdFusion服务器中，Java虚拟机路径设置为C：/ ColdFusion8 / runtime / jre所以这是我把我的java文件，这是正确的地方？我应该把.java，.class还是.jar放在那里？

In my Coldfusion server Java Virtual Machine Path is set to 'C:/ColdFusion8/runtime/jre', So this is where I have put my java file, is this correct? Should I put a .java, .class or .jar there?

文件名是否需要与类名一致？

Does the file name need to be consistent with class name?

有没有人有类似的工作示例代码可以尝试？

Does anyone have working sample code for something similar I can try?

推荐答案

在ColdFusion JVM的类路径，而不是在它的JRE dir。

You need to put the files on the the ColdFusion JVM's classpath, not in its JRE dir.

一般来说，如果你有一个jar文件，把它放在实例的 WEB-INF / lib dir，如果它只是一个类，将它放在 WEB-INF / classes 目录中，例如：将 C：\apps\adobe\ColdFusion\11\full\cfusion\wwwroot\WEB-INF \classes ，其中 C：\apps\adobe\ColdFusion\11\full\ 是我安装CF的地方， cfusion 是实例的名称。

As a rule, if you have a jar file, put it in the instances's WEB-INF/lib dir, if it's just a class, put it in the WEB-INF/classes dir, eg: for me the latter would be C:\apps\adobe\ColdFusion\11\full\cfusion\wwwroot\WEB-INF\classes, where C:\apps\adobe\ColdFusion\11\full\ is where I installed CF, and cfusion is the name of the instance.
