XSLT Task in ant gives waring "Warning: encoding "UTF-8" not supported, using UTF-8"

[Anoop Krishnan]

In my ant build process I use two kinds of xslt transform. One is the built in ant task and another one is a custom task which I programmed my self.
I use jdk / jre 1.6
and I use saxon9ee.jar for xslt processing
When I use the built in ant task as given below everything looks fine.
<xslt style="./release/${relNoteSource}" in="${jaxb.deploy}/${dir.resource}/dmf.xml" out="${build.root}/jar/${relNoteSource}" force="true"> <classpath location="../lib/saxon9ee.jar" ></classpath> <factory name="net.sf.saxon.TransformerFactoryImpl" ></factory> <outputproperty name="omit-xml-declaration" value="yes" /> <outputproperty name="indent" value="yes" /> </xslt>

In my custom ant task, which also does an xslt transform.
I get the transformer factory instance from net.sf.saxon.TransformerFactoryImpl.TransformerFactoryImpl (in the saxon9ee.jar) as given below

javax.xml.transform.TransformerFactory.TransformerFactory transformerFactory = net.sf.saxon.TransformerFactoryImpl.TransformerFactoryImpl.newInstance();

But this gives me a warning "Warning: encoding "UTF-8" not supported, using UTF-8"

Do you have an idea why and how can it be avoided ?

Well, in my case, it would be because I'd coded it as "UFT-8" (sic). My fingers don't always fire in the right order.

However, I find it interesting that the first item in the error is quoted ("UTF-8") and the second one is not (UTF-8).

I'm a big fan of putting quotes around values in error messages, BTW. Not only do they point out issues with things like trailing spaces, but messages like:

Error: cannot use class in this context.

waste a lot of time compared to:

Error: cannot use "class" in this context.

In cases where "class" is the name of a parameter.

Thank You Tim
But please note that this is a warning which I get when I run my ant task and there is nothing like "UTF-8" I used in my custom ant Task
I thought This is coming from the TrasformerFactory class that is why I replaced the built in TrasformerFactory to the one from Saxon this worked well with the built in xslt task but not in my custom implementation.

Or
Could you tell me where can I see the the Java source code for the ant XSLT task.

Could you tell me where can I see the the Java source code for the ant XSLT task.

Looks like it is in src/main/org/apache/tools/ant/taskdefs/XSLTProcess.java in the Ant source package.
