Infocenter as war file - dynamic plugin update [message #474173]

Hi,

I have a question about the dynamic loading of plugins when running the
infocenter as a war file. I'm running Tomcat 6 and my administrator holds
all the server controls such as when it is restarted, security etc. I just
have file system access to the eclipse directory within the webapp in
order to be able to update the plugins.

But when i add new plugins, how can i get them picked up without having to
get my administrator to clear out the 'work' directory where all the OSGi
configuration is and restart the server?

thanks in advance
tim

See this page of the Equinox project

http://www.eclipse.org/equinox/server/http_in_container.php

You need to enable framework controls in the web.xml file. Once you've done
that you can hit the following URL to redeploy eclipse inside Tomcat

http://<server>:<port>/<help webapp name>/sp_redeploy

For example

http://localhost::8080/help/sp_redeploy

One thing you need to watch out for here is to make sure that your plugin
manifest file has the correct information

Bundle-ManifestVersion: 2
Bundle-Version: 1.0.0
Bundle-Localization: plugin
Bundle-SymbolicName: com.foobar.doc; singleton:=true

Most importantly, the Bundle-SymbolicName needs to be the name of your
plugin. This will cause your plugins to be deleted and then redeployed to
the work directory. If you don't have this, the sp_redeploy will simply
ignore your custom doc plugins and newer version will not get deployed.

Thanks. I figured out I could do the same with the Tomcat manager
commands, though obviously they apply to all web-apps so I will look into
the sp_ commands as that may be a better way.

That looks like what I need. I cannot hot redeploy my WAR infocenter.
The application redeploys but server continues to serve the old HTML files.

If I configure the server with enabled framework controls, is there any
way to restrict who can give those commands? I'm exposing the
infocenter to the internet. Will anyone be able to give the sp_stop
command?

Thanks.

Peter

That I don't know the answer to. I suppose anyone can run that command.
