XML Elves

hi all,

i'm new to svg, and am trying to generate an svg document from xml and xsl, but the result has been discouraging..

i have done up appropriate configurations in stxx.pipelines (transform type as svg and direct to the xsl), web.xml (added the mimetype), and the struts-config file (to direct from the action class to the xsl). however, i'm still thrown with an error described below:

would appreciate any help from anyone, thanks a lot!
