Thanks I can't see why this is failing. It appears to be loading the class correctly, so the problem is in matching the method. You haven't shown us the Java class in question. One possible explanation is that the method is not static. Perhaps Xalan creates an instance of the class using the default constructor and then calls the method: Saxon will only call static methods, unless you supply an instance of the class as the first argument. Yes, there are differences in the way different Java processors call extension functions. It isn't standardised.
