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,
