[oXygen-user] Problem reloading jars that contains XSL

[Oxygen XML Editor Support (Adrian Buza)]

Hi,

The problem is you're using the "jar:file" protocol with a .jar file. 
The Java loading mechanism of jar files is meant for static Java 
resources (especially meant for Java class files) which are only loaded 
once when they are needed. So, any changes you do to the jar in the file 
system after the jar has already been loaded by the JVM will not be 
available until the JVM (Oxygen) is restarted. This is normal Java 
behavior and cannot be avoided. Oxygen cannot change this behavior as 
long as the jar gets loaded within its own JVM. Saxon transformations 
from Oxygen are run within Oxygen's JVM.
This works fine in the command line because the JVM loads and exits 
every time you run Saxon.

Oxygen provides an alternative means to do what you want via the 
"zip:file" protocol, but, obviously, this only works within Oxygen. Try 
using:
<xsl:import 
href="zip:file:/Users/cmarchand/devel/foe.jar!/path/to/file.xsl" />

Regards,
Adrian
