|I'm assuming that in a JBoss cluster Enterprise
|Applications are distributed from one node (possibly a
|Master) to all other nodes (possibly Slaves).
|
|I was considering this with respect to the Jetty
|integration.
|
|I'm assuming that a JBoss/Jetty cluster user may wish
|to deploy some legacy content, seeing as they have a
|shining new cluster available to them, and some
|cobwebby old files that they need to make available.
|
|By legacy I mean, content such as html, cgi etc.
|
|I can either ignore the problem, or as I have chosen
|to do - consider it (I do so since Jetty is also a
|decent WebServer and from a Jetty point of view it
|would be good to continue to support this
|functionality within a cluster).
|
|I assume that distributable unit of choice here for
|web-content is still a WAR (probably within an EAR -
|if you wish more control over your context).
|
|Thus if I wish to distribute some static HTML files -
|no problem. I can bundle them up into a WAR and hot
|deploy them onto one node - and they will be copied
|everywhere ?
Andreas has started tackling the problem as a JBoss Group employee. His
mission is to deploy a service to many targets using the new RH CL stuff .
The goal is to take a JDBC sar and mirror install it on 2 machines from
http. We are working and learning about it.
Installing web wars should not be much more complex.
|With CGI things get a little more difficult. Ideally I
|would like to bundle up the directory structure into a
|WAR and deploy it in the same way as the static
|content. However there are two problems with this.
|Firstly I would need to specify some mappings for the
|CGI Servlet - so it knew which files were scripts and
|what was static and secondly JAR seems to throw away
|executable bits on files - so unless I build a list of
|all of these (we're talking Unix now...) before
|archiving, then have the CGI Servlet reset these in
|it's init() method, WARs are not going to work for me
|here.
Jason wants to deploy native stuff to targets, it seems to me that a local
deployer could do wonders there.
|Is this how RH will distribute Applications ?
yes, but first we want to do the services. make sure that works and the war
shouldn't be more complex
|Can I deploy into any node directly - or only a Master
|node ?
It will be "a logical server" as a group of servers. We are also
researching the ways to make the grouping easy (jini?)
