libjkjni.so
hi,
in the catalina.out file i'm getting the following error:
INFO: APR not loaded, disabling jni components: java.io.IOException: no
jkjni in java.library.path
i'm confused as to why this library is being searched in the
java.library.path since this is a .so file. is there another jkjni
file?
i read someplace that libjkjni.so should be placed in
$catalina_home/bin so i put it in there. but, it didn't make a
difference. should it be placed somewhere else?
thanks,

Hello Vincent !
I'm a little short on time right now, so I will give you the abbreviated
version :
1. You will need to define $serverRoot externally. I have defined it
inside my /etc/profile as :
export serverRoot=/etc/httpd2
Just make sure it points to the directory where Apache's executables live.
2. You are also getting the error shm.init(): No file because you did
not define your shm (shared memory?) file in your workers2.properties.
My workers2.properties has the following section (put this at the
beginning of your file) :
[shm:]
info=Scoreboard. Required for reconfiguration and status with multiprocess
servers
file=/var/run/jk2.shm
size=1000000
debug=0
disabled=0
3. You are right in wondering about why Tomcat needs to read the
workers2.properties file. I'm not sure either. My theory initially was
this :
- Stage 1 : Tomcat starts up, tries to find if mod_jk2 exists.
- Stage 2 : If exist, Tomcat reads jk2.properties and sets up ports and
protocols ready for connection
- Stage 3 : Apache starts up. Loads module mod_jk2 and reads
workers2.properties
- Stage 4 : Apache attempts to "open a channel" (very Star Trek-ish ?)
to Tomcat via mod_jk2 and the defined socket type (channel socket/JNI/UNIX )
- Stage 5 : If everything starts up ok, Apache outputs a cryptic message
about "child init 1 -1".
From the responses to my posts, it appears that Tomcat does NOT
actually read anything, and that mod_jk2 does most of the work of
mediating a connection between the 2 software components (apache and
Tomcat). From my own tests, I was able to get mod_jk2 working with
channel sockets, the most basic configuration. I was able to confirm
from the error messages that, indeed, Tomcat does not appear to do
anything except startup and wait for connections on port 8080 (for
direct connections to it) and port 8009 (or whichever port your Tomcat
Coyote connector listens on). My tests with JNI gave very different
results, but I'm still working out the kinks in that one.

hi pascal,
that worked! the jk2.socket file is being created and apache seems to
be using it after i changed the permissions on the file. but, i am
getting the following error when the service starts:
Starting service Tomcat-Standalone

why would tomcat be trying to access the workers2.properties file? i
thought this file was for the web server.
thanks,

You need to create a symbolic link from your existing jkjni.so. For
example, suppose you have jkjni.so inside /usr/lib/apache, you will need
to do this :
ln -s /usr/lib/apache/jkjni.so $JAVA_HOME/jre/bin/libjkjni.so
export
LD_LIBRARY_PATH=$JAVA_HOME/jre/bin:$JAVA_HOME/jre/bin/classic:$LD_LIBRARY_PATH
Hope this helps !
