Error Page 404 in the web browser when accessing the links to install OEPE using the Eclipse Update Manager
By Csoto-Oracle on Oct 28, 2010
In the instructions page available here, at the "Using the Eclipse Update Manager" section there are 2 links (Galileo and Helios):
These are Eclipse Update site URLs to be used inside the Eclipse IDE, these are not browser specific URLs. Eclipse pings the URL for a content.jar file which contains a manifest of the update site content. Then the plugins from OTN will be installed. As long as Eclipse can find this information, the update site is working.
Since these URLs are not supposed to be accessed through a web browser, then the 404 error is thrown, but probably some kind of landing page will be implemented for users who try to connect to the update site in their browsers.
