Subject AW: HOWTO for Apache 2.0.43 and Tomcat 4.1.12 using mod_jk2
Date Sat, 05 Oct 2002 20:47:21 GMT
Sorry, of course it's "LoadModule" not "AddModule" ... I did it on RedHat
Linux 7.2, which might explain your pthread problem. Unfortunately I don't
have any experience with FreeBSD. maybe you should try going to the
jk/native2 directory and use -> configure -> make ... but that
didn't seem to work for me, could be a libtool problem.

It's really sad to see that the apache & tomcat developers are devoting so
little attention to mod_jk/mod_jk2, reminds me of the time before mod_ssl
was "built into" apache (IMO all closely dependent modules should be
integrated into apache, as they need to be modified with every apache
version). It was exactly the same situation, even most developers didn't
know which combination was stable.

I did step 1, and even went into the jk directory and did "ant native" as
well (per the jk/README.txt)
just in case...

I did step 2...

Step 3 will not work on Apache2 according to the Apache2 documentation :
"The AddModule and ClearModuleList directives no longer exist. "

As such, I did LoadModule, but that fails...
What OS are you running? I think that is part of my problem.
I am running FreeBSD. It said it couldn't find pthread_mutex_unlock --
so I tried installing pthread support... no luck...

Looking closer, I see that jk/native2/common/jk_mutex_thread.c is talking
about pthreads... and it says that it is a wrapper for apr....  Which is
probably where the problem comes from since the for the jk
directory was a pain to figure out, due to the fact that apache2 on FreeBSD
has files in /usr/local/lib/apache2, /usr/local/libexec/apache2,
/usr/local/www....  I tried to fix the to match the actual
but maybe the build isn't good enough to handle it...  the apr files are in
same directories listed there, and I modified the to
reflect that.
** So perhaps someone can tell me how to correctly build the "jk" directory
on FreeBSD?

But, in regards to your comment -- I completely agree... Try setting up jk2
jni and find out how many examples are out there... NONE that I could find
on google.
So, it is all guesswork since the documentation isn't really all there.
