apache2, tomcat4 and mod_jk/mod_jk2

[Alessandro Polverini <alex@nibbles.it>]

Hello,
I've originally posted this message to debian-java but I got no answers, I cross post here since I think it's relevant anyway.
Thanks,
Alex

-----------------------------------------
Hello,
I was unable to find mod_jk2 in Debian, so I tried to compile it myself
from sources got from apache site, but I went in trouble :(

Packages installed includes:
apache2-common 2.0.47-1
apache2-dev    2.0.47-1
apache2-mpm-wo 2.0.47-1
libapr0        2.0.47-1
libtomcat4-jav 4.1.28-1
tomcat4        4.1.28-1
tomcat4-admin  4.1.28-1

I then got jakarta-tomcat-connectors-jk-1.2-src-current.tar.gz from
jakarta site, untarred it, and following build instructions:

./configure -with-apxs=/usr/bin/apxs2

After that I do a "make", and after a couple file compiled fine it stops
telling me it does not find apr header files like apr_network_io.h and
apr_errno.h.

After researching a bit, I find these files in the dir
/usr/include/apr-0, so  I modify "by hand" a couple makefiles including
this dir in the include sources and I try to recompile.
This time some more files are compiled but the process fails with this
error:

make[1]: Leaving directory
`/root/jakarta-tomcat-connectors-jk-1.2.5-src/jk/native/common'
Making all in apache-2.0
make[1]: Entering directory
`/root/jakarta-tomcat-connectors-jk-1.2.5-src/jk/native/apache-2.0'

make[1]: Leaving directory
`/root/jakarta-tomcat-connectors-jk-1.2.5-src/jk/native/apache-2.0'
make: *** [all-recursive] Error 1

I also tried to compile the newest version of the connector (jk2) from
the following sources:
jakarta-tomcat-connectors-jk2-src-current.tar.gz

but this time the process does not even starts, here is the output of
make after having ./configure-d it:
list=' server/apache2'; \
for i in $list; do \
        echo "Making $target in $i"; \
        if test "$i" != "."; then \
        (cd $i && make) || exit 1; \
fi; \
done;

I'm really stuck.

Con anyone help me having mod_jk or mod_jk2 (preferred) for apache2?

Thanks very much for any help,
Alex

P.S.: Please be kind with me, I'm relatively new to Debian with source
packages...
