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.
i have a strange problem. im creating a PDF document from Java with apache FOP 1.1. If i create this file from eclipse, it works well. If i export my Programm as a jar file, it doesn work.

有人可以帮助我吗?
真诚的
推荐答案
当以jar运行时，程序似乎难以解析图像文件路径.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中运行时，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:
It looks like the program is struggling to resolve the image file paths when run as a jar. It's worth remembering the src attribute points to a URI rather than a file path and, depending on its structure, will be resolved differently when run directly rather than from an executable jar. The first thing I would try is to change the file path to something like this:
src="file:///C:/Users/user/Desktop/logo.jpg"
或者这个:
src='url("file:///C:/Users/user/Desktop/logo.jpg")'
您是否可以整理文件，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.很好地解释了这种方法的来龙去脉
Are you able to arrange your files so you can use relative paths instead? Absolute paths can be quite brittle to maintain. You may also want to consider including all the XSL and image files in the jar file itself. There's a nice explanation of the ins and outs of this approach here.
