When using CCRC with Eclipse version 3.3 (or later), why are my http proxy settings only being used some of the time?
As of Eclipse 3.3, the mechanism Eclipse uses for storing and applying its own http proxy settings has changed. This new mechanism conflicts with that used by CCRC. This issue also affects applications based on Eclipse 3.3 and later, such as Rational Application Developer.
In order to work around this problem, the CCRC http proxy settings in the Window->Preferences->Team->ClearCase Remote Client->Connections dialog and the Eclipse http proxy settings in the Window->Preferences->General->Network Connections must both be set to the same values.
