What encoding do you use?
Unfortunatly Java uses different names than XML for some encodings.
If the (Java based) processor does not translate these encoding names before opening its output stream you will typically get such an error.

Hi,
I have been using XSLT for almost a year now. In my past projects, I have been using Saxon and Xalan due to the transformation required xsl:key. In my current project, I have started to explore XT for the performance improvement it provides. Currently, I ran into a problem trying to output non-XML string. It always seems to give me a problem at xsl.parse, getting a NullPointerException with OutputStreamWriter (code and exception at end of email). The weird thing is, my method outputs XML string is just fine. Also I have another xt() method with a different signature outputs to a file instead of string, that works fine for both XML and non-XML output. Also, both Saxon and Xalan methods I have ouputs XML and non-XML string just fine. So I am little perplexed as what causes this exception ONLY when using XT outputs non-XML string. Any help and suggestions would be most welcomed.
Thanks,
