> Tapestry uses some special extensions to StaX (out of Woodstox) in the template parser.
This leads to the problem that Tapestry will usually not run on any application server because
the appservers will use their own implementation of Stax.
> There is a workaround but a main stream web application framework should run on JEE compatible
web and application servers without tweaking.
> The main problem is in org.apache.tapestry5.internal.services.TemplateParserImpl.<init>(TemplateParserImpl.java:44).
Here, XMLInputFactory2 is asked for an instance - but XMLInputFactory2 does not implement
the method newInstance. This is delegated to XMLInputFactory. So, the original XMLInputFactory
is used - which returns the platform implementation of Stax.
> Workaround:
> Add the system property below to Application Server (either via startup script or admin
console):
> -Djavax.xml.stream.XMLInputFactory=com.ctc.wstx.stax.WstxInputFactory
