Major Description
The startup script run.sh provides an option (-n, --netboot) for starting the AS on a server using a minimal set of jars, and obtaining the bulk of the JBoss distribution from a remote web server:
./run.sh -c netboot -n http://my.remote.host/jboss-dist
In order for the netboot mechanism to work, two elements are required:
the JBoss distribution on the remote server needs to have all deploy directories in unexploded form (i.e. http-invoker.sar and other archives need to be zipped up into files)
(ii) the remote web server through which the JBoss distribution is made available needs to support the WebDAV PROPFIND command
See the admittedly old documentation in section 1.3 at http://docs.jboss.org/jbossas/jboss4guide/r2/html/ch01.html.
In trying to test the run.sh -n option in EAP 5.0.1, I found that the netboot option generated multiple exceptions. Here are the steps I took to try to test the option:
1. Install a copy of Apache on my local machine
2. Set up a WebDAV compatible directory in /var/www and test access to this directory using a command-line client (such as cadaver)
3. Create a copy of jboss-eap-5.0.1 in which a new server configuration, netboot, is defined and where netboot is a copy of default in which all exploded directories in netboot/deploy and netboot/deployers have been zipped up (in the manner used in the examples from the documentation listed above)
4. Copy the jboss-eap-5.0.1 distribution to the WebDAV server
5. From a copy of jboss-eap-5.0.1 which has had all but the ./bin directory removed, start JBoss using the netboot option
> ./run.sh -c netboot -n http://localhost:80/webdav/jboss-eap-5.0/jboss-as
