Hi.
I am running Linux 6.1 and trying to get Apache 1.3.6 to recognize
the Apache Jserv 1.0 module when I do 'httpd -l'. Apache 1.3.6 came
from a tar file off of apache.org as did Jserve 1.0. I have JSDK2.0 and
JDK1.1.7 installed. Apache was built with DSO support using this
script:

#./configure --prefix=/usr/local/apache_1.3.6 \
--enable-rule=SHARED_CORE \
--enable-module=so \
--enable-shared=max
#make
#make install

No errors with anything and it said '+ enabling generation of Apache
core as DSO'
'+ using
-ldl for vendor DSO support'

Then I built JServ using this script:

#./configure --prefix=/usr/local/jserv \
--with-apache-install=/usr/local/apache_1.3.6 \
--with-jdk-home=/usr/local/jdk117_v3 \
--with-jsdk=/usr/local/JSDK2.0/lib/jsdk.jar \
--enable-apache-conf
#make
#make install

Again, no errors and this message 'Apache Version: 1.3'
'Module Type:
dynamic (DSO will be used to link mod_jserv into server dynamically)'

Looks good so far, right?

Then I rebuilt Apache 1.3.6 with this script to enable the jserv module
as DSO and activate it:

#./configure --prefix=/usr/local/apache_1.3.6 \
--enable-rule=SHARED_CORE \
--enable-module=so \
--enable-shared=max \
--add-module=/usr/local/ApacheJServ-1.0/src/c/mod_jserv.c \
--enable-shared=jserv
#make;make install

No errors..message says:
+ on-the-fly added and activated jserv module
(modules/extra/mod_jserv.o)

I checked and the "LoadModule jserv" line had been added in
/usr/conf/httpd.conf but not in the
/usr/local/apache_1.3.9/conf/httpd.conf Does this matter? (I did add
it myself in apache_1.3.6 just to see. Didn't work). Which .conf file
is read on apachectl start? I thought it was the one in apache_1.3.6

I restarted apachectl as well as stopping and starting it and 'httpd
-l'still did not show mod_jserv.c in its list of compiled in modules.

I am at a loss. Any info would be helpful. THANKS!!

I believe you can't have both (DSO for jserv & httpd -l response). See
my response to your previous post.

Okay, everything looks pretty good.

It most definitely matters. Get your PATH straightened away, get rid of
multiple Apache executables & conf files, or be _specific_ in executing
and accessing these files, or I supsect you'll continually have problems.

only if you run the apachectl script from the correct directory. cat
the apachectl scripts that are on your machine and look at the
configuration section near the top. See HTTPD? It defines which httpd
executable is executed.

As expected. So far the only problem you have that I can see are:

1 - multiple copies of apache of which to be aware/careful
2 - possibly missing a line or two in your httpd.conf file

In httpd.conf, either use something like this to include your jserv.conf file

Include /usr/local/jserv/jserv.conf

or include all the directives themselves in the httpd.conf file.

In either case make sure the LoadModule & AddModule directives are used.
AddModule was left out in my case. For me, they look like this at the
top of my jserv.conf file.

LoadModule jserv_module libexec/mod_jserv.so
AddModule mod_jserv.c

Are we getting closer?

Thank you very much for your info. I apologize for posting the message
twice, but I thought I lost the first one.

You were right about checking my path. I had another apachectl and
http.conf that was messing me up. Now everything runs where it is
supposed to be.

But, I have another problem now :-) I added the "Include" line
in apache_1.3.6/conf/httpd.conf to include the path to jserv.conf.

Then I added the "AddModule" line in jserv.conf (by the way, mine had
the "Include" line but not the "AddModule" line. Just like you said
yours did, eventhough the documents say it should add it. hhmmm.)
anyway, I then ran apachectl start and got this error message:

Syntax error on line 218 of /usr/local/apache_1.3.6/conf/httpd.conf:
Cannot load /usr/local/apache_1.3.6/libexec/mod_jserv.so
into server: /usr/local/apache_1.3.6/libexec/mod_jserv.so: undefined
symbol: jserv_error_exit
/usr/local/apache_1.3.6/bin/apachectl: cannot start

To me this looks like a possible problem with the version of apache
since I found jserv_error_exit in the mod_jserv.c file.
So, I tried loading apache_1.3.9 and doing everything all over again and
got the exact same error.

The docs that I have read show no sign that these versions are
incompatible. Again here is what I am running.....

RedHat Linux 6.1
Apache 1.3.9
JSDK 2.0
JDK 1.1.7
Apache JServ 1.0

Thanks!!!!
