File transport reader exceptions when updating the Ecllipse

[mattwolfe]

Whenever I try to update the Oxygen Eclipse plugin, I get a "'File Transport Reader' has encountered a problem. Transfer Exception" error. The Eclipse download site I have specified is http://www.oxygenxml.com/InstData/Edito ... e/site.xml.

Usually I am able to install the updates after 3-4 attempts, but never the first or second time. Other members of my team experience the same issue. Any idea what is causing this error?

Hi,

Are you behind a proxy (HTTP or SOCKS)?
An HTTP proxy sometimes caches retrieved files. This can cause problems when the remote files get updated, but the proxy keeps returning an outdated cached file.
As it happens, today we released a new maintenance build of v15.1 (2013110816), so the files from the Eclipse download site have been updated. Please check if the build number corresponds when you attempt to update Oxygen.

Regards,
Adrian

I'm on a corporate network. I have no idea if IT is using a proxy. Is there a way I can tell? Or would I have to try to contact someone in our IT department?

Hi,

For Windows you can check for proxy settings in Control Panel > Internet Options, Connections, LAN Settings. If you're not allowed to change them, the settings are grayed out.

The Automatically detect settings check box is selected and the Use a proxy server for your LAN check box is not selected. I assume that means I am not behind a proxy.

I now have a user who cannot even install the plugin at all. Normally after 2-3 attempts the installation succeeds. But for this user the download always times out and she gets this error. She's tried on 2 different networks.

Any ideas on what's causing this?

Would it be possible to download what I need to host my own update site? I already have an update site I maintain for a different Eclipse plugin.

Hi Matt,

If you open our site.xml Eclipse update site in a web browser:

http://www.oxygenxml.com/InstData/Edito ... e/site.xml

you will see it references different JAR archives for different Eclipse versions. Unfortunately JAR libraries for update sites are signed and they contain inside references to our web site so I don't think this would work.

As an alternative you should download our ZIP distribution and unzip it in the "eclipse/dropins" folder:

http://www.oxygenxml.com/download_oxyge ... os=Eclipse
