So if the answer is wrong, you can probably blame > the Microsoft JVM. Yes, this is a bug in Microsoft JVM. But the result described by Ken Holman is oposite to one that can be observed if RFC 2396 were not followed. It looks like it is a bug in Microsoft's libraries for handling file paths, not URLs. > As others have pointed out, this comes down to a > question of whether the JVM is handling "\" in accordance with RFC 2396. SAXON 6.5.3 and XT both use java.net.URL to resolve paths. Recent versions of Sun JVM parse URLs in strict accordance to RFC 2396. However, a different usecase shows that SAXON 6.5.3 (I am sorry I didn't test XT when I had access to a Windows machine and I cannot say for sure from the source code) displays a different but still non-conformant behaviour. It happens not because the library deviates from RFC 2396 (Sun JDK 1.3.1 runtime follows it strictly) but because SAXON sets systemId of the included stylesheet by calling createURL on the file's name, and then setSystemId on the created file. createURL contains explicit code to re-slash the path (ExtendedInputSource.java). Thus, it is not related to the extent Java Runtime follows RFC 2396, but is caused by the way SAXON computes systemId of a file, namely, by forcing reslashing the path to the UNIX way, which leads to non-conformant behaviour. I would prefer the url's not to be reslashed on Windows platforms, as it hides errors and complicates debugging; however, as David Carlisle has mentioned, the client-side URL transformation is a tricky part.
