The WebDAV scan just builds a list of what it thinks should be deployed. The scanner then: 1) Undeploys anything previously deployed that wasn't found 2) Checks last-modified for anything currently deployed and re-deploys if needed 3) Deploys anything new that was found
I don't use the last-modified value from the scan as each unit may have a different watchUrl from the the deployment url. Instead it relies on DeployedURL.isModified() which implies a network trip. So, yes, hot deployment is supported even over http but it would be possible to optimize this, especially for the remote situation where things are always packed and watchUrl == url, if you think it's necessary. There are a couple of other things that could be looked at here as well: * Should getWatchUrl() be part of the (Sub)Deployer contract? * Should we tidy up the mechanism for local copies and hook in the deployment cache? * Should we support unpacked remote (maybe with a helper to auto-jar on the server)? * Should we be smarter about re-deployment (e.g. factor in dependencies)? and generally, can deployment be simplified? It seems to have evolved and be more complex than necessary, or maybe I'm just tired :-) Jeremy PS I need to get the netboot-demo finished for Jason - this was a pre-req to simplifying that. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Sacha > Labourey > Sent: Thursday, December 19, 2002 9:57 AM > To: [EMAIL PROTECTED] > Subject: RE: [JBoss-dev] Committed support for remote deployment > scanning > > > BTW, do you support hot-(deployment/re-deployment/undeployment) > as well i.e. > do you read the lastModified timestamp from the remote webdav server > > > -----Message d'origine----- > > De : [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED]]De la part de > > Jeremy Boynes > > Envoyé : jeudi, 19 décembre 2002 18:51 > > À : Jboss-Development > > Objet : [JBoss-dev] Committed support for remote deployment scanning > > > > > > I have commited changes to URLDeploymentScanner that use WebDAV to scan > > http: locations, allowing the same config to be booted locally or via > > netboot. > > > > There are a couple of changes that may impact existing configurations: > > * It needs to know whether to scan or deploy a supplied URL.
