问题：
来自Apache FOP 1.1的PDF格式图像，带有Java
邵正雅
我有一个奇怪的问题。我用apache FOP 1.1从Java创建了一个PDF文档。如果我从eclipse创建这个文件，它工作得很好。如果我把我程序导出为jar文件，它不能工作。
XSL-FO文件是：

有人能帮我吗？

我也面临同样的问题。对我来说，修复它的方法是为您的FopUserAgent对象设置基本路径，这样它就知道您的图像的路径。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，为了使它与罐子一起工作，我不得不添加以下导入：
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());
原因很明显是fop。jar使用与xmlgraphics commons jar（处理图像）相同的设置名称。所以为了没有fop。jar覆盖了我必须使用的设置xmlgraphics。
不幸的是，这只适用于我的机器。在其他PC上测试jar会再次导致相同的错误。也许你运气更好。如果是这样，请告诉我。(运行Debian 8，OpenJDK7，FOP 1.1)

看起来程序在作为jar运行时很难解析图像文件路径。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运行时解析方式不同。我要尝试的第一件事是将文件路径更改为如下内容：
src="file:///C:/Users/user/Desktop/logo.jpg"
或者这个：
src='url("file:///C:/Users/user/Desktop/logo.jpg")'
你能安排你的文件，这样你就可以使用相对路径代替了吗？绝对路径可能很难维护。您可能还想考虑在jar文件本身中包含所有XSL和图像文件。这里有一个关于这种方法来龙去脉的很好的解释。
