Package javax.xml.transform not present on Android SDK

[GoogleCodeExporter]

What are you doing to produce the error?
1. I am using the LeafNode.unsubscribe() method from pubsub extension.
2. It makes a call to the XmlUtils class which imports classes from
javax.xml.transform package.
3. This package does not exist in the Android JDK. Here is the message that
I get :

What is the expected output?
All but a such exception :)

What do you see instead? (Please attach a debug enabled logcat)
see the logcat attached

What version of aSmack / Android / Device do you use?
aSmack: from the  rtreffer/asmack trunk on github
Android: SDK 1.6 (API 4)
Device: an Androidx86 running on a VM

What server do you use? Is there a public server to reproduce the problem?
It is a local server not accessible from the web.
Openfire, trunk version

What else might help us to reproduce and hunt down the problem?
The problem is that the package javax.xml.transform is not part of the
Android SDK. Actually, we can fix the bug by removing the part of the code
which uses javax.xml.transform, I checked that it is never used today (the
method called by "LeafNode.unsubscribe()" is in the same class but does not
use the javax.xml.transform package), but smack's developers could use it
soon, so there is probably a better solution.

I attach the source I used to get the bud, and the logcat.

Kind Regards,

Paulo

I'm sorry about that.

should fix it.

Could you rebuild your asmack version after a git pull and report the result? 
I'd be
happy to publish a fixed version....

It works very well, thank you very much !

I think you should remove the imports too, but it works like that.

Kind Regards,

Paulo

Imports are invisible in the .class file, and not worth the hassle (at the 
moment).

Anyway, thanks for testing!
