Subject	[platform-update-dev] Question: Smart incremental updateability in the Updater component

Hi

I have a question on the Updater component in the Eclipse Platform.
This is regarding the smart update capability of the Updater component.

Context
-------------
My firm is planning to create a rich client tool.
The major platform requirements for this tool are -
     1. A native user experience on Windows
     2. Smart updating capability, thru incremental updates.
Much like
Windows update
     3. Administrator access should not be required to install
the application

Because of criteria 3, we have decided to go with Java instead of
.NET, as we can package a JVM with our app and refer to it in a
relative manner.
Because of criteria 1, we are evaluating between then Eclipse RCP and
the Netbeans platform, in which Swing is so amazingly fast.

My question
------------------
Can the Updater component do SMART, INCREMENTAL patching of an RCP application?

The functionality required is as follows -
>> Our app will be a single plug-in for the Eclipse RCP platform
>> This single plug-in will have multiple jars corresponding to the
components of the app
>> If there are 5 jars in the plugin v1.0, in which all jars are
also v1.0
i.e.
plugin v1.0 =
                 jar1 v1.0
                 jar2 v1.0
                 jar3 v1.0
                 jar4 v1.0
                 jar5 v1.0

Then i update the plugin to v1.1, in which only jar1 is updated
i.e.
plugin v1.1 =
                 *** jar1 v1.1
***
                 jar2 v1.0
                 jar3 v1.0
                 jar4 v1.0
                 jar5 v1.0

My requirement is that the Updater SHOULD ONLY DOWNLOAD jar1 v1.1 to
update my RCP application plugin to v1.1

>> Is this functionality supported by the Updater component?
Or does the Updater download the whole plugin v1.1 again?

Thanks in advance
Arun
