Re: Repeated "load-on-startup" niggle

[Joe Francis]

Chris, thanks for responding.  I think I understand.  Sanity check: the 
filter is not even mentioned anywhere in the webapps/hal heirarchy, 
right?  That hierarchy is totally unaware of the filter.

If that's the case then all is making sense now. 
thanks again,
-joe

Hi Joe,

I'm not sure exactly what your query is but the setup I have is a "/"
and a "/hal" Context.  The Filter I am using to direct any requests to
"/" to "/hal" lives in the WEB-INF/classes dir of the "/" context.
In my case I used the Tomcat default dir of "../webapps/ROOT" for the
"/" docBase.
Further. the configuration for the Filter and the URL pattern to
fire it is in the web.xml file in that same WEB-INF dir.  I do use
"/*" as the URL pattern, but remember that these URL patterbs are
relative
to the Context the web.xml file is in.
i.e.

webapps/ROOT/WEB_INF/web.xml	 
URL pattern of "/*" matches http://myserver/*

webapps/hal/WEB_INF/web.xml
URL pattern of "/*" matches http://myserver/hal/*
Sorry if I've missed your point.

Regards,
Chris

Howdy,
A javax.servlet.Filter is one nice clean way.
     

Apologies if this is dumb q: Googling the jakarta site and 
reading the 
tomcat o'reilly have left me confused on this.

Isn't the filter part of web app?  From jakarta:

   

Filters are configured in the deployment descriptor of a web 
application
     

And in o'reilly the filter and filter-mappnig tags are 
discussed in the 
web.xml section. 
Doesn't this raise a namespace issue?  If your servlet-mapping is to 
/foo, then a filter on /* seems like it will either never 
fire, or else 
be ambiguous with other /* filters in other web apps (such as 
the /bar 
webapp, with it's own /* filter). 

The original poster had a /hal context and a / context.  Does 
the filter 
solution require the / context to remain?  Or is that unneeded?

thanks for any unconfusion,
-joe
