RE: compiling mod_jk under AIX (or any other OS it wasn't develop ed on)

[Kajen, Michael]

Hi,
Some months ago, I built mod_jk for HPUX and AIX with some difficulty. (The
Solaris build was postponed indefinitely.)
I read all the posted documentation, and nothing compiled 'out of the box'.
I found that many people posted identical errors that I encountered.
The basic problem, as I see it, is that the native compilers are too stupid
to compile the dialect of C code now used in public domain software. (I say
this having been a compiler implementer on a variety of platforms many years
ago).
Based on the errors I encountered with the build scripts and the C code, it
is my opinion that the build scripts were never tested on these platforms.

While it is certainly possible to hack the connector source to compile with
the various native compilers, I think a more realistic approach is to use
GCC, which is what I ended up doing.

I'm having the same build war with my Solaris 7 box.  Have the build scripts
using cc in places even when gcc is specified, have it telling me my apxs
path is invalid when I am absolutely sure it is valid and is not corrupt in
any way.  Every time I fix one thing, another is a problem.

Anyone know what platform you can actually compile the latest version of
JK/JK2 on without errors?  Isn't the whole purpose of having a buildconf and
configure script to solve most of those "where's the library" and other
platform issues?

Michael,

I pinged Localhost and got the message:

Reply from 127.0.0.1: bytes=32 time<10ms TTL64

I presume from this all is fine, as I have a reply?

HI,
See if you can ping localhost. Maybe something happened to your dns
settings. mk

Subject: (OT) Cannot see Localhost on Apache


Hello,
 
Sorry for the off topic manner of this email but I am having trouble
with my Apache server and was wondering if anyone on this list can help
me?
 
For about a year I had Apache 1.3.20 set-up on my Windows 98SE machine
running PHP 4.1.1 (and Coldfusion) on it with no problems. I would type
http://localhost/ <http://localhost/>  (or http://127.0.0.1/
<http://127.0.0.1/> )  in my browser and be able to see the directories
with all my files in them and edit them accordingly.
 
However, last week I started up Apache and opened a browser and typed
Localhost but nothing happened! All I would get would be a white blank
screen and if I typed in the address of a specific file within the
directory I would get a "Pager cannot be displayed" error.
 
I tested this in IE, Netscape and Mozilla (along with clearing the cache
in each browser) and all of them were the same.
 
I decided to uninstall Apache 1.3.20 and upgrade to 1.3.26 figuring that
if I started with a newer version of Apache the problem would be
eradicated and I  would have a more up-to-date version of the server.
 
This I have done, but still I cannot gain access to any of my files and
still it gives me a blank white screen if I type Localhost and a "Page
cannot be displayed" error message if I try and navigate to a specific
file within the directory.
 
I have scanned the Apache web site, trawled through the newsgroups,
studied my config file indepth, but cannot see where the problem lies.
 

Could someone please take a look at my config file and try to see why
this is happening because as far as I can tell everything is fine and I
haven't changed anything since the last time it worked OK?
 
Please disregard the fact that I haven't loaded the PHP modules yet (and
Coldfusion as well) as I will do this after I have managed to sort out
the Localhost problem.
 
Your help would be very much appreciated.

Can tomcat 3.3 run cgi scripts

[Kajen, Michael]

Hi,
I see that Tomcat 4.0 has CGIServlet.
At the moment I'm stuck on tomcat 3.3.
Is there a way to configure it to run CGI scripts?

Thanks for any help.

RE: mod_jk w/ tomcat 4: worker file not found

[Kajen, Michael]

Hi,
I ran into a similar error message recently, where Apache would not start
with the message:
[emerg] Error while opening the workers

I tracked this down to a routine in  jk_connect.c.

I discovered that in the workers.properties file I had to use the actual
host name, not 'localhost'.
Don't know why 'localhost' didn't resolve.

Since it appears you turned on tomcat debugging, have a look at the
mod_jk.log. 

Hope this helps.

hi, folks.

i'm running tomcat + apache via mod_jk on openbsd 3.0, and have had some
problems with mod_jk. after starting apache (via apachectl sslstart), i
consistently see the following in apache's error_log:
---
[Fri Aug  2 11:51:48 2002] [error] Error while opening the workers, jk will
not work

[Fri Aug  2 11:51:53 2002] [error] (2)No such file or directory: Error while
opening the workers, jk will not work
---
playing around with mod_jk.c and jk_map.c, the error condition occurs
because conf->worker_file is non-null when called during set-up in
jk_set_worker_file(), but is null by the time that jk_init() calls
map_read_properties().

i'm guessing that i've either configured something incorrectly or have some
incompatible components; can anyone advise? if i set conf->worker_file to my
workers.properties file's absolute path before passing it to
map_read_properties(), the error is no longer reported and i can make a
socket connection based on a redirect, etc.

system details:
OpenBSD 3.0
mod_jk 1.2.0
apache 1.3.19
tomcat 4.0.4

has anyone else run into this? or is there something odd about the
