When Eclispe SDK distribution is used as platform to install JBT there is not possible to add new connection to Remote Systems. Remote system view is empty and when New Connection menu is selected displayed wizard for New Connection has no Remote Server Type to select.
When Eclipse JEE distribution is used for JBT everything works fine.
Probably JBT installation should add necessary plugins/features to Eclipse to be able to use RSE or we have to change JBT documentation and make Eclipse JEE distribution required for RSE to be working.
