[kepler-users] Problem running simple workflows involving RExpression actor

[Jianwu Wang]

Hi Tristan,

    It's great you found the reasons. It's weird that you were able to 
run workflows without java being in the path. One more tip, besides 
information shown on console using command line, Tools->'Check System 
Settings' also show some system information.

Best wishes

Sincerely yours
