How to add "pre-installed" plugins? [message #877879]

I am going to host my own instance of Orion. How do I extend Orion so my own plugins are pre-installed for any user accounts (just like Authentication, File Client, Jslint etc)?

Thanks,

Rafael

So far, I am suspecting the pre-installed plugins are baked in Orion by virtue of being part of the org.eclipse.orion.client.core bundle web/plugins directory.

If that is correct, I could as a workaround just add my plugin to that location post install as a file system link. But that wouldn't cut it, as my plugin makes HTTP requests and I believe same-origin policy requires me to publish it from the same server it sends requests to.

Hah, it seems the defaults.pref file determines what plugins are loaded by default, and it does accept any plugin URL, I was wrong about bundled plugins having to be part of the Orion distro.

For now, I will get by with modifying that file (while I am there, I will remove the plugins I don't need). Any more civilized way of modifying the list of installed plugins (that would survive an Orion reinstall, for instance)?

You've got it. The defaults.pref is the only way we currently configure the default set of installed plugins. I have entered a bug for finding a nicer way to do this on the server:

In case you still want to deploy something that would otherwise conflict with the same-origin policy,
this is a description on how to provide a separate bundle that runs in the same domain as Orion does.

(Everything just as far as I understand it. Maybe there is a better way)

For that you need to modify the server.configurator bundle.
Its plugin.xml defines which bundle's folder gets loaded to what url path.
Of course, if you want to load your plugin at startup you would still have to modify the defaults.pref.

Let's say you have the following bundle structure

com.corp.myplugin (bundle id equals project root name)
|_ web 
    |_ html,js files
    |_ myplugindefinition.html

In the server.configurator bundle you need to add some configuration code to its plugin.xml.

First you have to add an addtional httpcontext to the httpcontexts extension:

<extension point="org.eclipse.equinox.http.registry.httpcontexts">
      <httpcontext
            id="org.eclipse.orion.server.configurator.httpcontext.myplugin">
         <resource-mapping
               bundle="com.corp.myplugin"
               path="/web">
         </resource-mapping>
      </httpcontext>
      ... other httpcontexts ...
</extension>

And finally you need to define to which path the http context is supposed to be delivered

   <extension
         point="org.eclipse.equinox.http.registry.resources">
      <resource
            alias="/myplugin"
            httpcontextId="org.eclipse.orion.server.configurator.httpcontext.myplugin">
      </resource>
      .....
   </extension>

On the next restart the embedded Jetty Server should deploy the content of your plugin's web folder to

http: //oriondomain/myplugin

Leo,
I followed the process you outlined to pre-install a plugin.
Apparently, the plugin's content is not accessible at "http://{oriondomain}/{myplugin}
Are there any additional changes required?
thanks.
