We are working with a pure E4 Application.

After reading some posts and all the necessary stuff to get working the p2 update we still have a problem.

All seems to work as long as we test on a file repository. The update is done, no error.

But if we copy the repository to our Web-Server we got an error. The first part - check if an update is needed works...

        final UpdateOperation operation = new UpdateOperation(session);
        final SubMonitor sub = SubMonitor.convert(monitor, "Checking for application updates...", 200);
        IStatus status = operation.resolveModal(sub.newChild(100));
        if (status.getCode() == UpdateOperation.STATUS_NOTHING_TO_UPDATE) {
            LOG.debug("nothing to update");
            return status;
        }
        if (status.getSeverity() == IStatus.CANCEL) {
            LOG.debug("update - cancel");
            throw new OperationCanceledException();
        }
        if (status.getSeverity() != IStatus.ERROR) {
            LOG.debug("update - install");
            final ProvisioningJob job = operation.getProvisioningJob(null);
            status = job.runModal(sub.newChild(100));
            if (status.getSeverity() == IStatus.CANCEL) {
                LOG.debug("update - install - cancel");
                throw new OperationCanceledException();
            } else if (status.getSeverity() == IStatus.OK) {
                LOG.debug("update - install - ok");
            } else {
                LOG.debug("update - install - " + status.getSeverity() + "/" + status.getMessage());
            }
        }

after the check in

status = job.runModal(sub.newChild(100));

we got an error: >> An error occurred while collecting items to be installed

Why there is a difference between file and http?? no other message
And - the plugin to update is now on the client side, but the client allways tries to update...

Any hints?

Thx
Beat

Can it be that you miss the HTTP-Provider from ecf?

Thanks Tom

But no, the httpclient is available. And as i wrote in my question - it is strange because the changed plugin and feature was transfered, so no http problem in sense of the protocol. And in the artifact.xml the changed versions are available.

So the problem is why i get an error on update? And why the client tries to reupdate if the plugin is updated?

Is it possible that your HTTP-Server is compressing stuff? We had
problems in one of our product because the sizes in the artifact didn't
match anymore what the server delivered?

So we turned of gzip-ing in our apache config for the p2 sites.

Could be - Thanks. I will check it. In the artifact.xml I see different size for the updated feature and plugin. I will update you...

I tested both local and server (http) update again. The download size is the same but:
A difference between the two artifact.xml files

    <artifact classifier='osgi.bundle' id='org.sat4j.core' version='2.3.0.v20110329'>
      <properties size='1'>
        <property name='download.size' value='210700'/>
      </properties>
    </artifact>
    <artifact classifier='org.eclipse.update.feature' id='ch.sbb.test.p2.feature' version='1.0.3'>
      <properties size='1'>
        <property name='download.size' value='724'/>
      </properties>
      <repositoryProperties size='1'>
        <property name='artifact.folder' value='true'/>
      </repositoryProperties>
    </artifact>

    <artifact classifier='org.eclipse.update.feature' id='ch.sbb.test.p2.feature' version='1.0.1'>
      <properties size='1'>
        <property name='download.size' value='725'/>
      </properties>
      <repositoryProperties size='1'>
        <property name='artifact.folder' value='true'/>
      </repositoryProperties>
    </artifact>

The update with http leads to an artifact.xml with two feature entries with version 1.0.1 and 1.0.2, the updated one and the old one.
If I update over file:/// the second (red) is deleted.

So how can I influence this behaviour or what is the reason? Where is this update done and why this behaviour?

I guess this forum is the wrong one to discuss p2 strangness ;-) Are you
saying that the artifact you get from the server is different than the
one you generate as part of your build?

In the meantime I tried another way. Our webserver is an ms iis server. So I tried the same with a jetty server - and - it works. So at the end I can't say what didn't work (a better error handling/returning would be nice) but I know to not use MS IIS for the repo.

Thx for your support Tom

Just for those with the same problem...
For the IIS update site we had to define a default mime-type with the extension "*" and content-type "application/x-zip-compressed".
In the binary folder of the repository the product had the extension of the version.qualifier (.201301280838).

Beat,

I am experiencing the same issue - have to manually add mime type on IIS server. Can you elaborate on how did you add mime type with extension '*'? At what point in the build and where do you do this? Also, looking for the answer for wildcard support, I stumbled upon this: http://support.microsoft.com/kb/326965, are running IIS with version prior to 6.0?

Hi Alex,

Beat is a colleague of me and pointed me to your question, so here are some details on how we fixed this issue.

You need to start the IIS Manager. Then navigate to your site and doubleclick MIME Types. Now you see the list of all known MIME types. Click Add... on the Actions on the right side of the manager, type ".*" as the file name extension and "application/x-zip-comressed" as the MIME type. Last step is to restart the web site. That's it.

Kind regards,
Yves
