mod_jk / Tomcat 6 and ErrorDocument

Hi to all,

Did some of you experienced problems with mod_jk 1.2.26 (and maybe
earlier release) and Apache 2.x ErrorDocument directive.

In one of my configuration I set :

    ErrorDocument 404 /gen_error404.html
    ErrorDocument 500 /gen_error500.html
    ErrorDocument 503 /gen_error503.html

    JkMount /sitea/* wsitea
    JkMount /siteb/* wsitea
    JkOptions +ForwardDirectories


When I look for a unexisting resource under Apache 2 control, I got
the content of gen_error404.html.
Also if the tomcat is unavailable I got back gen_error503.html page.

But if I'm looking for an unexisting resource under Tomcat control, I
get back the standard Tomcat 404 error instead of the
gen_error404.html.

Did there is some 'special settings' or configuration to be done on Apache/jk ?

Regards

Let's roll as soon as those things are done.
I'll double check the status edits for the new params,
and as soon you finish chunked encoding we are
ready to go.

Sorry to join the discussion to late, but yes: I think it always was
like that, no way of overwriting the Tomcat error pages inside Apache. I
put it on my personal TODO for mod_jk long ago :(

Mladen did some pretty interesting things lately. I have one question to
him open, to which I want to come back later this week, see

   http://marc.info/?l=tomcat-dev&m=120852255309277&w=2

I have some spare time later this week and next weekend and plan to
finally do the IIS chunked encoding stuff. If we don't find anything
else important we should be able to have a testing tar ball at the end
of the month and soon after start the releasing process. We are a couple
of months over a regular schedule, but 1.2.26 was not too bad, and some
of the new features will be worth the longer waiting time (Mladen's
probing thread, per mount reply timeouts, IIS chunked encoding).

I don't know if Mladen shares this opinion?

Rainer

Right, sorry for the noise.
There is no way to have that at the moment.
The code I've quoted is when there is error in sending the
error page from the Tomcat, so in that case Httpd takes over,
and sends intended page.

For normal replacement of error pages
this would have to be added to mod_jk.
It's a nice feature to have, but you'll have
to wait for 1.2.27 ;)

As you could see the Content-Length is '0', status is 404 but I didn't
get the error page :-(

I'm using Apache 2.2.9 / mod_jk 1.2.26 and Tomcat 6.0.18, everything
on an XP box.

Did the 'if (!r->sent_bodyct && r->status >= HTTP_BAD_REQUEST) {' is
allready in 1.2.26 ?

I added to the conf/web.xml :

  <error-page>
      <error-code>404</error-code>
      <location>/empty-error.html</location>
  </error-page>

  <error-page>
    <error-code>500</error-code>
    <location>/empty-error.html</location>
  </error-page>

  <error-page>
    <error-code>503</error-code>
    <location>/empty-error.html</location>
  </error-page>


I tried with an empty-error.html and then with an inexisting error
page, but I didn't get the ErrorDocument defined in Apache 2.2.x ;(

Try creating custom 404 page for tomcat with zero length body.
In that case Apache httpd error page will be shown
