OpenSAML user discussion

[Chad La Joie <>]

You need to understand how encoding works in the various places.

Files have a particular encoding and that's what your java.io classes 
operate on.  The DOM has an independent encoding which indicates the 
encoding used for the containers of data within the DOM.  You can (and 
I've accidentally done it before) use different encodings for each.

So, what have you is correct.  It's doing exactly what you told it to. 
Take UTF-8 DOM and write it out to a file encoded with another encoding.

As I already told you the last time you asked, you can use the 
XMLHelper.writeNode method to do this.

XMLHelper.writeNode(youNode, new FileWrite("/path/to/you/file.xml"))
