I needed to install the WebObjects deployment environment on a CentOS 5.2 64 bit box, and by combining tidbits of information from the mailing lists and the wiki, I was able to have a working environment. This is how I did it :
Install Sun Java JDK
1. You need to install a Java SDK. DON'T use the Java stuff from GNU, use a JDK from Sun instead. In my case, I installed JDK 1.5.0_16 from a RPM I got from java.sun.com. I also created two symbolink links :
and you need to change your path in your bash profile (_~/.bash_profile) to have this path :
2. Get the WebObjects installer from mDimension's Web site :
and install it like this :
(You can also install 5.3.3 instead of 5.4.3)
WebObjects frameworks are now installed in /opt
3. Now we need to change some permissions. To follow the conventions from Mac OS X, we will create two users to run wotaskd and Monitor under this user :
and fix some permissions :
4. Now we can start wotask and Monitor
Edit the bash profile of the appserver, and add this line :
and run it manually in your current shell :
You can start wotaskd and Monitor to make sure that they run without any problems :
5. Last step : compiling and installing the Apache module
A possibly helpful note for rank beginners like me: this got me a working Apache on Ubuntu:
On that system the relevant command names are apache2ctl and apxs2, and the document root is /var/www (not /usr/local/apache/htdocs as in the example below).
(you will need httpd-devel and gcc)
Alternative way of installing apache:
yum install httpd
yum install mod_ssl
yum install httpd-devel
chkconfig httpd on
.. default install location is then /etc/httpd
Get the source of the module (adaptor) from Wonder. You only need the Adaptors (and its subfolders) folder.
Edit make.config and change the value of ADAPTOR_OS to LINUX. (this can be found in Adaptors directory (JS))
Go to the ApacheXX folder that match your Apache version. In my case, I'm using Apache 2.2 built from source and installed in /usr/local/apache.
In another case I ran 'make CC=gcc' in the Adaptors directory then moved to the Apache2.2 directory. (JS)
Instead of copying the WebObjects directory, you can use a alias to point to the folder inside NEXT_ROOT. In your Apache configuration, add something like :
and add a directive to allow fetching files in this directory:
Or (depending on your Apache configuration) you could use a symbolic link.
You also need, as explained by the adaptor's README file, to add this directive in httpd.conf :
If you don't add it, you will get 403s (Forbidden) HTTP errors.
If you want to keep /cgi-bin/WebObjects as the base URL, you will need to remove a line in httpd.conf. Find the line that starts with ScriptAlias /cgi-bin and comment it out, or else Apache will try to find a WebObjects CGI in /cgi-bin instead of loading the adaptor from the Apache module.
And edit /usr/local/apache/conf/extra/webobjects.conf to comment the LoadModule WebObjects_module line. You can also change the WebObjectsAlias property, in my case I use /apps/WebObjects. Last step : add the following line in httpd.conf (near the end):
Check for any errors with apachectl configtest, and if everything's ok, you are good to go. You can install your first app, don't forget that your app must be accessible by the appserver user or the appserveradm group. If your app don't start or if Monitor complains about a path, it might be a permission problem.
Jerome Chan told me that you can check if the Apache module is loaded by doing this :
Auto Start WOTaskd and WOMonitor
One last thing, you need a init script to start wotaskd and Monitor at boot time. This is the one I wrote :
You also need to add the script with chkconfig so that everything start up after a reboot. If you named the above script as "webobjects", do :
If SELinux is enabled on your system, wotaskd won't run because of SELinux policies. You need to run :
