AW: XSLT transformation with a xindice result

I cannot believe that it is so hard to convert a XML source into an output
stream :-( I added javax.xml.transform.* but I still get cannot resolve
symbol errors. Do I really need this DOMSource-thing to convert the XML
source which comes from the xindice database with a xslt stylesheet? I`m
even happy if the result of the transformation is listet as an out.println()
in the JSP.

 

Thx Christoph

You don't import 'javax.xml.transform.Transformer', try adding <%@ page
import="javax.xml.transform.*" %>.

 

Hope that helps

Betreff: XSLT transformation with a xindice result

I try to transform a XML document  I get from the xindice database. First of
all, I transform the result of the xpath query into a DOMSource. Then I try
to transform this DOMSource with the help of a xslt stylesheet. But I can´t
even compile it (see errors below). I have no idea why I get the “cant
resolve symbol” error. I think I included all classes.
