[News.eclipse.dsdp.mtj] Re: Unable to use night build

[Spinelli Fabrizio <fab.spinelli@xxxxxxxxx>]

Hi MTJ guys. I've "resolved" my problem. Thanks for reading naive 
questions and sorry for wasting your time. As i supposed it was a 
problem with JRE, as mentioned I've installed JDK 6 Update 6 on my 
system, but Eclipse continued to start with JRE 1.4! Simply add -vm 
switch pointing to correct JRE path in eclipse.ini resolved the problem.
I'll open a new thread for a new ( also naive :) ) question.
