[news.eclipse.technology.equinox] p2 error: "Unable to read repository"

[maxime valy <valy@xxxxxxxxxxx>]

Hi

I'm trying to add auto-update capabilities to our RCP-based software 
using the p2 system. I followed the "Adding Self-Update to an RCP 
Application" tutorial [1] and used the latest version of P2Util.java 
from the CVS repository [2]. The software has a simple test plugin that 
I would like to update and everything is packaged as a feature.

By copying the plugins dependencies from the prestartupdate example, 
I've managed to export my application and make it connect successfully 
to the HTTP repository listed in my p2.inf file, using the fully 
qualified action 
"org.eclipse.equinox.p2.touchpoint.eclipse.addRepository" [3]. As 
requested on this page [4], the "org.eclipse.ecf.provider.filetransfer" 
plugin is included.


In my server logs, I can see the following lines:

192.168.5.10 - - [15/Sep/2009:11:54:03 +0200] "HEAD 
/UpdateSite/content.jar HTTP/1.1" 200 - "-" "Jakarta 
Commons-HttpClient/3.1"
192.168.5.10 - - [15/Sep/2009:11:54:03 +0200] "GET 
/UpdateSite/content.jar HTTP/1.1" 200 26169 "-" "Jakarta 
Commons-HttpClient/3.1"


However, on the client side this error occurs:

Checking repository http://192.168.0.103/UpdateSite
ERROR:Unable to read repository at 
http://192.168.0.103/UpdateSite/content.jar.

After reading this post [5], I've added all of the 
"org.eclipse.equinox.p2.*" plugins minus the sources ones but without 
more luck.

I've tried to change the repositories in the p2.inf file and used those 
of Galileo, but the error is the same ("Unable to read repository at 
http://download.eclipse.org/releases/galileo/content.jar";).

Finally I checked the behaviour of the prestartupdate example, and it 
appears that the same error occurs with both repositories (mine and 
galileo).

So what did I did wrong? I checked every documentation I could find on 
the net and didn't find the answer. This message on the list [6] looks a 
bit similar but the response links to a thread problem which I don't 
have (yet).


Thanks in advance,
Maxime
