Hi Konstantin,

Thanks for the clarifications.  I stand corrected on the failover - could be a 
Tapestry issue not Tomcat.  


However, bottom line, Tomcat 7 works a bit differently from Tomcat 5 with 
respect to welome files, probably respecting the new servlet spec 

To your question as to "what point merging algorithms are not followed", please 
try this inside your application context and you will probably see the same: 

 

    <welcome-file-list>
     <welcome-file />
    </welcome-file-list>

This seems to tell Tomcat 7, in plain English, "there are no welcome files, 
don't bother looking for them anywhere" ...   


In other words, it is NOT merged with container as intended/indicated below in 
your message.

It sounds like behaviour that can be controlled by
"resourceOnlyServlets" option in <Context>,
See
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html

The current behaviour is caused by compatibility concerns with earlier
versions of Tomcat. Read the doc for more details.

Unlikely. You have to provide specific example to confirm that. The
above mentioned option could explain that as well.

> However     <welcome-file-list />

conf/web.xml is not just default. It is merged with app's web.xml
using the rules for merging web fragments, as specified in the Servlet
3.0 Rev.a specification.  If current behaviour contradicts with
specification, please cite what point in merging algorithm is not
followed.

Best regards,
Konstantin Kolinko
