确认正在加载jar文件

Question

如何确认我的JAR文件已在Coldfusion中加载？我在CF10上.

我目前收到此错误:

Could not find the ColdFusion component or interface org.apache.batik.transcoder.image.PNGTranscoder. 

我的网站结构如下:

/root
/root/application.cfc
/root/jar/batik-1.7/

在我的application.cfc中,我有以下代码:

<cfset This.javaSettings = {loadPaths: ["jar/"],loadColdFusionClassPath: true,reloadOnChange: true,watchInterval: 2}>

这是我调用一切的代码:

更新#1

我正在检查administor并找到了Settings Summary哪个列出了CF Server Java Class Path.我添加了jar文件的位置并重新启动了服务器.即使路径存在于管理员的类路径中,我仍然会得到相同的错误.

更新2

添加了缺少的属性"type"并收到以下错误:

java.lang.NoClassDefFoundError: org/apache/batik/dom/util/DocumentFactory

Line 554: transcoder = createObject("java", "org.apache.batik.transcoder.image.PNGTranscoder").init();

更新3

我在application.cfc中有这个

<cfset This.javaSettings = {loadPaths: ["jar/"],loadColdFusionClassPath: false,reloadOnChange: true,watchInterval: 2}>

我打电话onApplicationStart(),仍然得到同样的错误.

此时,我已经删除了ColdFusion类路径中的条目,现在它已回到默认值为空.

我希望它能够使用javaSettings变量加载jar文件,因为我在共享主机上.

Answer 1

更新：

（聊天总结）Batik 1.7 包含两个已与 CF 10 捆绑在一起的 xml 解析库的较新版本。加载这两个版本将导致 ClassCastException

org.apache.xerces.jaxp.SAXParserFactoryImpl 无法转换为 javax.xml.parsers.SAXParserFactory

为了避免该错误，请从目录中删除这两个 xml jar batik-1.7/lib，这样就不会加载它们：

  /batik-1.7/lib/xerces_2_5_0.jar
  /batik-1.7/lib/xml-apis.jar

而且，loadPaths不是递归的。因此，如果子文件夹中包含任何 jar，则还必须包含这些子文件夹的路径。IE

   This.javaSettings = {loadPaths: ["/jar/batik-1.7","/jar/batik-1.7/lib"]};

如果您对 进行更改this.javaSettings，请务必重新启动应用程序以确保应用更改。

找不到 ColdFusion组件或接口

当您使用 时createObject，您需要包含对象“类型”。否则，它使用默认类型“组件”。意味着 CF 正在搜索具有您提供的路径的组件/cfc ，即“org.apache.batik.transcoder.image.PNGTranscoder”。由于您的应用程序可能不包含具有该路径的 cfc，因此您会收到上述错误消息。

"java"为您的所有调用添加类型createObject，它应该可以工作：

createObject("java", "org.apache.batik.transcoder.image.PNGTranscoder").init();
