java.net.URISyntaxException [英] java.net.URISyntaxException

问题描述

我得到了这个例外。但这个例外不再重现。我想得到这个原因

I have get this exception. but this exception is not reproduced again. I want to get the cause of this

Exception Caught while Checking tag in XMLjava.net.URISyntaxException:
Illegal character in opaque part at index 2:
C:\Documents and Settings\All Users\.SF\config\sd.xml
stacktrace net.sf.saxon.trans.XPathException.

为什么发生此异常。如何处理，以便它不会重现。

Why this exception occured. How to deal with so it will not reproduce.

推荐答案

基本上C：\Documents and Settings \所有用户\.SF\config\sd.xml是路径名，而不是有效的URI。如果要将路径名转换为file：URI，请执行以下操作：

Basically "C:\Documents and Settings\All Users\.SF\config\sd.xml" is a pathname, and not a valid URI. If you want to turn a pathname into a "file:" URI, then do the following:

File f = new File("C:\Documents and Settings\All Users\.SF\config\sd.xml");
URI u = f.toURI();

这是在Java中将路径名转换为有效URI的最简单，最可靠和最便携的方法。

This is the simplest, and most reliable and portable way to turn a pathname into a valid URI in Java.

但你需要意识到file：URI有许多警告，如 File.toURI（） 方法。例如，在一台机器上创建的file：URI通常表示另一台机器上的不同资源（或根本没有资源）。

But you need to realize that "file:" URIs have a number of caveats, as described in the javadocs for the File.toURI() method. For example, a "file:" URI created on one machine usually denotes a different resource (or no resource at all) on another machine.
