I have a happy update to this matter... I was running on port 8080 and had
a production copy of apache on port 80. When I shut down the other
version of apache things work fine. I believe that only one instance of
apache, regardless of the port, can bind to one IP address.
Everything is working now, but from what I've read in the FAQ-o-matic,
ajp11 connection failures are a symptom of many types of problems. I am
happy to share my build and installation steps if it helps anyone. I
built it as a static compilation, not DSO. They
are listed below (pardon the verboseness):
1. Extracted apache_1.3.9.tar and Apache_JServ_1.0.tar.gz into
/usr/local/src
2. Downloaded the JSDK 2.0 from http://java.sun.com/products/servlet
3. Installed JSDK into /usr/JSDK2.0
4. Run the following command to test a vanilla instance of apache:
cd /usr/local/src/apache_1.3.9
configure
5. The necessary makefiles should now be made. Now run make:
make
5. Run make install as apache to put it into /usr/local/apache
make install
This will create some directories under /usr/local/apache and
put all the binaries in place.
Note: The installer changes the group to staff for all files.
This has caused no problems with Apache
6. Before we can test Apache, set the following directives in the
/usr/local/apache/conf/httpd.conf file. They should already
exist and need only to be changed.
User nobody
Group nobody
ServerName schubert.spinweb.net
port 8080
7. Start the server from user apache with this command:
/usr/local/apache/bin/apachectl start
8. This should respond that httpd started. To test the server,
go to:
http://schubert.spinweb.net:8080/
The port is 8080 since non-root users cannot run servers on
ports under 1023. The server should be run on port 80 when
root runs the server later.
9. Build Jserv for static compilation into Apache:
/usr/local/src/ApacheJServ-1.0/configure \
--with-apache-src=/usr/local/src/apache_1.3.9
--prefix=/usr/local/jserv
--with-jdk-home=/usr/java1.2
--with-jsdk=/usr/JSDK2.0/lib/jsdk.jar
10. Make the new version:
cd /usr/local/src/ApacheJServ-1.0/
make
make install
11. Rebuild Apache:
/usr/local/src/apache_1.3.9/configure \
--activate-module=src/modules/jserv/mod_jserv
cd /usr/local/src/apache_1.3.9
make
/usr/local/apache/bin/apachectl stop
12. Add the following to the /usr/local/apache/conf/httpd.conf:
Include /usr/local/src/ApacheJServ-1.0/example/jserv.conf
13. make it:
make install
/usr/local/apache/bin/apachectl start
/usr/local/apache/bin/httpd -l
14. Restart the Apache server:
/usr/local/apache/bin/apachectl restart
15. Test the example servlet at:
http://schubert.spinweb.net:8080/example/Hello
