java - 找不到 ColdFusion 组件或接口(interface) javaloader.JavaLoader

Question

不确定为什么这在我的本地不起作用。它在我的远程测试环境中运行。当前代码:

<cfset local = {}>
<cfset local.paths = []>
<cfset local.paths[1] = GetDirectoryFromPath(GetCurrentTemplatePath()) & "lib\jsoup-1.7.2.jar">
<cfset local.javaloader = createObject("component", "javaloader.JavaLoader").init(local.paths)>
<cfset jSoupClass = local.javaloader.create( "org.jsoup.Jsoup" )>

<cfset local.javaloader....> 出错

有什么想法吗？ #local# 正在获取正确的 jsoup-1.7.2.jar

浏览器上抛出错误:

Answer 1

环境更改和 NoSuchTemplateException 这两个提示建议您查看 Coldfusion Administrator 中的映射。您可能忽略了 Javaloader 映射或在当前环境中错误地定义了它。

假设您正在使用 Mark Mandel's Javaloader ，并且您将其解压缩为文件夹 javaloader_v1.1。那么您应该将映射定义为:

逻辑路径:/javaloader

目录路径:{absolute_path_to_folder_javaloader_v1.1}/javaloader/
