Re: Tomcat and HTTPD on the same box: What's the best mod_jk2 protocol? SUCCESS!!

[Andrew Clute]

Well, I finally got it work! It took piecing somethings together, but 
here is what I did...

On RHEL3 with pretty much stock everything.
my configure:
./configure --with-apxs2=/usr/sbin/apxs --with-apr-lib=/usr/lib 
--with-tomcat-41=/usr/local/jakarta-tomcat-4.1.30 
--with-java-home=/usr/java/j2sdk1.4.2_04 --with-jni

Then the key to getting libarputil linked into libjkjni.so:
After running .configure, I modified the makefile inside of 
./server/apache2. I changed the following block:

ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS}
endif
to:
ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS} -laprutil-0
endif
(NOTE: addition of -laprutil-0 to second declaration line)
I had followed this from somewhere else, but added the -laprutil-0 to 
the first line, and not the else. When I added it to only the else, it 
worked! I am not sure why, my Linux C programing is really rusty, as I 
am a Java Developer! :)

Works now! So the original question remains: When HTTPD and Tomcat are 
on the same box, is Unix Socket better than TCP? Is there any 
discussion about the pros/cons of Unix socket?

Err, it won't. Just reminding you that you have to run it. One last 
attempt : did you run buildconfig before configure ? I understand from 
someone else running RHEL that you need to run that.
