Sessions problem with TC4 on Win XP Home when browsing from "localhost"

[Jeff Corliss]

Hi all,

As if the subject line wasn't long enough... here's an
interesting problem I'm hoping someone can help me
with.  Basically, I have a Struts-based app which I'm
deploying on TC4 on a Win XP Home machine while
developing.  When I access the app via a browser on
another machine on the network, all is fine.  When I
access the app from the machine on which tomcat is
running (using localhost), it seems that sessions are
constantly being re-created.  So, every time I perform
a login to my app (which saves an object in the
session for "proof of login" etc.), the next page I
hit that requires being logged in sends me right back
to the login page (because the object is not in the
session).  The session now has another ID and "isNew".
 As I mentioned, very same app accessed from another
machine works perfectly.

Here is a quick undown of the environments:

Localhost machine:
Win XP Home, jdk=1.3.1_02, Tomcat=4.1.8 thru 4.1.10,
Struts=1.1b1, Internet Explorer=6.0.

Other machine:
Win95, IE=5.0

I thought perhaps the problem was with IE 6, so I
downloaded Mozilla 1.1 and tried the app that way with
same result.

Weird huh?  Any ideas are greatly appreciated
(including pointing out obvious errors on my part).  
-JC

RE: Sessions problem with TC4 on Win XP Home when browsing from "localhost"

[Jeff Corliss]

Hmmm ... not sure that I really specified the host
name per se.  Also, one thing I forgot to mention...
the app works fine for "localhost" access running on a
Win2k machine.  Could this be some XP specific
problem?

Tomcat 4.04 SSL with client Auth?

[Jeff Corliss]

Hi all,

Just got the 4.04 final (been working pretty much only
with 3.x before).  Quick question: does Tomcat 4.04
now support client certificate authentication under
SSL?

TIA

Distribution/Licensing question

[Jeff Corliss]

Quick newbie question, and if its just a case of RTFM
(which I have, but maybe I missed it), please feel
free to say so ...

I am writing a webapp that includes tag libraries and
the intent is to sell this to multiple customers, each
of whom will be designing their own JSPs using those
tags.  Now, since that means the JSPs will need to be
compiled by Tomcat at least once at each customer's
site, does this mean I need to actually distribute not
only Tomcat but also the JDK (not just the JRE)?  If
that is the case, does that mean I have to make an
arrangement with Sun for licensing the redistribution
of the JDK?

Many thanks,
Jeff

Re: Tomcat 3.2.4 xml parsing of web.xml

[Jeff Corliss]

Ever since I switched from 3.2.3 to 3.2.4, I notice a
lot of the following types of messages in the log
output onscreen:
=
Warning: validation was turned on but an
org.xml.sax.ErrorHandler was not
set, which is probably not what is desired.  Parser
will use a default
ErrorHandler to print the first 10 errors.  Please
call
the 'setErrorHandler' method to fix this.
Error: URI=null Line=22: Element "servlet-mapping"
does not allow "url-pattern"
here.
Error: URI=null Line=24: Element "servlet-mapping"
requires additional elements.

allow "servlet" here.
Error: URI=null Line=31: Element "servlet-mapping"
does not allow "url-pattern"
here.
Error: URI=null Line=33: Element "servlet-mapping"
requires additional elements.

Error: URI=null Line=35: Element "web-app" does not
allow "servlet" here.

Error: URI=null Line=44: Element "web-app" does not
allow "servlet" here.
Error: URI=null Line=49: Element "servlet-mapping"
does not allow "url-pattern"
here.

Does this mean my web.xml is out of whack, or is maybe
something else wrong?  Everything seems to work ok as
per what I have in the web.xml.

Thanks,
Jeff

"Scheduled Process" servlet: possible?

[Jeff Corliss]

Hi all,

Is it possible to have a servlet's service method
auto-invoked on a scheduled basis by its container? 
Like say for example you want to have your app do some
auto-archiving of old data on a regular basis or
something like that?

Thanks,
Jeff

Troubles with the list: 

Streaming files from Tomcat thru JK and IIS: No Headers (?)

[Jeff Corliss]

I'm having a problem with my IIS/Tomcat integration
using the JK connector.  Regular pages and servlet
mapped extensions work fine, but when I try to send
files using the ServletOutputStream, it does not work
properly when going thru IIS<->JK<->Tomcat.  I wind up
getting the content returned to the browser with
absolutely no headers (at least from the perspective
of doing a "View Source" on the returned "page").  I
am setting headers including content type, length, and
disposition.  Also, if I go directly to Tomcat using
its port #, the files come down the wire with the
headers and all and the appropriate plug-ins get
called by the browser, etc.  

Anyone know a solution for this?

Thanks,
JC

RE: ERROR while running servlet on mac os X

[Jeff Corliss]

Found this in the release-notes-4.1.txt:

Enabling invoker servlet:

Starting with Tomcat 4.1.12, the invoker servlet is no
longer available by 
default in all webapp. Enabling it for all webapps is
possible by editing
$CATALINA_HOME/conf/web.xml to uncomment the
"/servlet/*" servlet-mapping
definition.

Using the invoker servlet in a production environment
is not recommended and is unsupported.

Hope that helps,
JC
