Hi Stefan,
If you are using the built-in extension functions, try turning on the
following feature:
private static final String ENABLE_EXTENSION_FUNCTIONS =
"http://www.oracle.com/xml/jaxp/properties/enableExtensionFunctions";;
tf.setFeature(ENABLE_EXTENSION_FUNCTIONS, true);
If you are using user-extension functions, then add the following:
private static final String EXTENSION_CLASS_LOADER =
"jdk.xml.transform.extensionClassLoader";
tf.setAttribute(EXTENSION_CLASS_LOADER, cl);
where cl is the user-specified ClassLoader that will load external
extension function classes, e.g.
runWithPermission(() ->
Thread.currentThread().getContextClassLoader())
HTH, and please let me know if it works for you.
Thanks,
Joe

Hi,
I've been told to ask for advice here.
Over the past few weeks we've adapted the Apache Ant code base to JDK 9
well enough that Ant's own test suite works - almost.
The onyl remaining issue really goes back to Java 1.7 and JAXP 1.4 when
secure processing was introduced. If you are running an XSLT transform
and it needs extensions - say the Xalan redirect extension - you can't
do it if a SecurityManager has been set.
https://bz.apache.org/bugzilla/show_bug.cgi?id=51668
This is causing quite a few problems for users running Ant from within
IDEs which typically install SecurityManagers. One such instance it
Ant's own<junitreport> task which uses XSLT and the redirect extension.
Back in Java 1.7 we "solved" the problem with a hack. We simply disable
secure processing mode via reflection
https://github.com/apache/ant/commit/fe829a9d0fa679df3ae2cc4803e5236ed2ed5c7b
The module system now breaks the hack as we can no longer access the
necessary field via reflection.
Before we try to find new clever or stupid workarounds we may as well
ask for advice on how to do it properly.
This is our use-case: The user wants to execute Ant's<xslt>-Task from
within Eclipse which has installed a SecurityManager and the transform
requires an extension. How can we make this work?
Cheers
Stefan
