問題描述

我需要將 java 文件導入 Coldfusion 8 頁面，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，我有以下代碼:

In Coldfusion I have the following code:

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

然后我收到錯誤

對象實例化異常.找不到類:你好

Object Instantiation Exception. Class not found: Hello

在我的 Coldfusion 服務器中，Java 虛擬機路徑設置為C:/ColdFusion8/runtime/jre"，所以這是我放置 java 文件的位置，對嗎?我應該在里面放一個 .java、.class 還是 .jar?

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?

文件名需要和類名一致嗎?

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

有沒有人可以嘗試類似的工作示例代碼?

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

推薦答案

您需要將文件放在 ColdFusion JVM 的類路徑中，而不是其 JRE 目錄中.

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

一般來說，如果你有一個jar文件，把它放在實例的WEB-INF/lib目錄，如果它只是一個類，把它放在WEB-INF/classes 目錄，例如:對我來說后者是 C:appsadobeColdFusion11fullcfusionwwwrootWEB-INFclasses，其中 C:appsadobeColdFusion11full 是我安裝 CF 的地方，cfusion 是實例的名稱.

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:appsadobeColdFusion11fullcfusionwwwrootWEB-INFclasses, where C:appsadobeColdFusion11full is where I installed CF, and cfusion is the name of the instance.
