RE: tomcat 4 vs 5 form based container auth filters

FYI this is catered for in tomcat 5 with the filter-mapping/dispatcher
element (see servlet 2.4 spec).

Thanks to Bill Barker for the info.

I can see Yoav is blitzing the mailing list right now. Perhaps you'll 
get a more authoritative answer from him or the other hardcore tomcat 
people.

One of the problems of excluding filters from the authentication request

is to do with character-encoding in the request - I remember someone 
whose realm included users with user-names containing accented 
characters that had to be converted to the correct character-encoding 
for the realm database. He had used a filter to do it but obviously had 
to find another way.

 AFAIK it has something to do with providing a clean seperation between

 the authentication (tomcat) and the application (your filter).
 
 I think there were probably several reasons though for it, which 
 outweighed the reasons against, and I have heard a few of them.

Yes your observations are correct. It's my understanding that filters 
are not invoked until after authentication. i.e. after the form-based 
login.

I have no experience of site-mesh, but it seems a bit weird anyway to 
put decorations on a page via a filter - surely you should be 
encapsulating that sort of stuff in a JSP or taglib?

how does it cater for it? Are you saying you can use web.xml to map 
filters to the j_security_check URL?

get a more authoritative answer from him or the other hardcore tomcat 
people.

One of the problems of excluding filters from the authentication request

is to do with character-encoding in the request - I remember someone 
whose realm included users with user-names containing accented 
characters that had to be converted to the correct character-encoding 
for the realm database. He had used a filter to do it but obviously had 
to find another way.

 What reasons did you hear? :-)
 
 Whilst not knowing the full reasons, it would be nice if there was
some
 config switch to control this, other wise it increases application
 maintainence overhead if you want to change the look and feel.
 
 I'll see if I can find anything in the tc5 release notes on this.
 
 Thanks again

 AFAIK it has something to do with providing a clean seperation between

 the authentication (tomcat) and the application (your filter).
 
 I think there were probably several reasons though for it, which 
 outweighed the reasons against, and I have heard a few of them.

Hi Adam,

Why do you think this behaviour changed from tomcat4 ?

I haven't gone into the full architecture of sitemesh, as yet, but I
know it includes a filter.

Yes your observations are correct. It's my understanding that filters 
are not invoked until after authentication. i.e. after the form-based 
login.

I have no experience of site-mesh, but it seems a bit weird anyway to 
put decorations on a page via a filter - surely you should be 
encapsulating that sort of stuff in a JSP or taglib?

Hi,

Initial observation indicates that filters get executed when a form

for


form based container auth is served - under tomcat 4, but not under
tomcat 5. 

I'm using sitemesh.  The decorations go on the form based login page
under tomcat 4, but not under tomcat 5. 

I need to do more research, but can any one add to this?

Thanks
Martin
