[opencms-dev] Problem while trying RSS-NewsModule ..

[Peter Glantschnig]

hi,

well it's definitly a problem with the XSLT transformation...that's only
used for the extern examples.

I don't really know where the problem is, but I guess it has something to do
with some wrong Java libraries, that can be found in your classpath. 

If you have J2SE 1.4.1 and nothing else it should work. Have you ever
installed a version of the Xalan-Java project? If so, there could be problem...

However I'm quite sure the problem is within those lines:

TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new StreamSource(new
StringReader(xsl_content)));
StringWriter html_content = new StringWriter();
transformer.transform(new StreamSource(new StringReader(xml_content)), new
StreamResult(html_content));

return (html_content.toString());

Maybe put the code in a little class and try if it works anyway? (but don't
forget to replace the xml content)

I hope it helped,
Peter
