问题描述

我有一个奇怪的问题。 即时通讯使用apache FOP 1.1从Java创建PDF文档。 如果我从eclipse创建此文件，则效果很好。 如果我将Programm导出为jar文件，则无法正常工作。

XSL-FO文件是： 

<?xml version="1.0" encoding="ISO-8859-1"?>

谁能帮我？

看起来像程序在以jar运行时正在努力解析图像文件路径。 值得记住的是，src属性指向URI而不是文件路径，并且根据其结构，直接运行而不是从可执行jar运行时，解析方式会有所不同。 我要尝试的第一件事是将文件路径更改为如下所示： 

src="file:///C:/Users/user/Desktop/logo.jpg"

或这个： 

src='url("file:///C:/Users/user/Desktop/logo.jpg")'

您是否可以排列文件，以便可以使用相对路径？ 绝对路径可能很难维护。 您可能还需要考虑将所有XSL和图像文件包含在jar文件本身中。 有这种方法的来龙去脉的一个很好的解释在这里 。

我遇到了同样的问题。 对我来说，解决此问题的方法是为FopUserAgent对象设置基本路径，以便它知道图像的路径。 然后，您可以指定相对于此路径的图像。 

// images are located in or in subfolders of baseDir
String baseDir = /some/path/to/includes/
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
foUserAgent.setBaseURL(baseDir);

此外，为了使其与罐子一起使用，我必须添加以下导入： 

import org.apache.xmlgraphics.image.loader.ImageManager;
import org.apache.xmlgraphics.image.loader.impl.DefaultImageContext;
/* Added this line to my code to get these imports. Not using it at all */
ImageManager imageManager = new ImageManager(new DefaultImageContext());

原因显然是fop.jar的设置使用了与xmlgraphics-commons jar（用于处理图像）相同的名称。 因此，为了不让fop.jar覆盖设置xmlgraphics，我不得不使用所述导入。

不幸的是，这似乎只在我的机器上起作用。 在其他PC上测试jar会再次导致相同的错误。 也许你有更多的运气。 如果是这样，请告诉我。 （运行Debian 8，OpenJDK7，FOP 1.1）
