ECF Filetransfer Proxy [message #479587]

We are using Equinox P2 to update our RCP Application programatically from
a remote repository via HTTP.

Now that we have P2 up and running, we do not find any documentation on
how we can configure proxy support for ECF etc.

within our environment some workstations work correctly with P2 on some of
them we get

Caused by: org.eclipse.ecf.filetransfer.BrowseFileTransferException:
Proxy Authentication Required at
org.eclipse.ecf.provider.filetransfer.httpclient.HttpClientF ileSystemBrowser.runRequest(HttpClientFileSystemBrowser.java :202)

now we got this switch as a tip
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors= org.eclipse.ecf.provider.filetransfer.httpclient

it works somehow but we don't know why.

1. Is there any documentation about proxy konfiguration and ECF ?
2. where can we find the possible configuration options for ECF ?

thanks!

I'm assuming that you must have an NTLMv2 network/proxy. If so, then
this page explains why excluding the httpclient provider works:

http://wiki.eclipse.org/ECF_Filetransfer_Support_for_NTLMv2_ Proxies

Not specifically...and that's because ECF uses the Eclipse platform
proxy API to detect/use proxy configuration information. So I think
that all you would have to do to configure proxies differently is to
also use the proxy API (or just use the Eclipse preferences UI under
General->Network Connections...which uses the Eclipse platform proxy API
underneath).

Note that the current version (Eclipse 3.5) proxy API does *not* support
transparent detection/configuration of NTLMv2 proxies. This is
something we/ECF are working on with Pawel of the platform team in bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252002 (see comments 60,
61, and comment 64).

> 2. where can we find the possible configuration options for ECF ?

As outlined above, ECF uses the platform proxy API to get proxy
configuration. So if you want to setup the proxy info for your app, and
have ECF filetransfer use it, you can either use the proxy API
programmatically (and have your own user interface), or even use the
Eclipse preferences User interface.

Please let know if you would like more info, obviously with bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252002 and the need to
workaround httpclient and NTLMv2 issues much of this is in flux right now.

One thing I forgot to add. As described above, ECF does use the
platform proxy API to get proxy configuration. However, this can be
overridden by using the
IRetrieveFileTransferContainerAdapter.setProxy(org.eclipse.e cf.util.Proxy)

method. If this (manual/programmatic) configuration is used it
overrides the use of the Eclipse platform proxy API-specified configuration.
