Hi Joao,

Did you do a make clean make ?
If you did, is teh following OK?
 root > .x umain.C(7,100) 
leave Root
in a new session
root > .x display.C

Do you see the display of the Jets and of the Misc object?
Could you click with the middle button in the display pad,
then at the command line, execute
root > gPad->ls();
You should see something like:
 OBJ: ATLFMCMaker       MCMaker WH, H-->bb, W-->lnu : 0
 OBJ: ATLFMuon  ATLFMuon        ATLFast muon class : 0
 OBJ: ATLFJet   ATLFJet ATLFast jet class : 0
 OBJ: ATLFJet   ATLFJet ATLFast jet class : 0
 OBJ: ATLFMisc  ATLFMisc        ATLFast miscellaneous class : 0
 OBJ: ATLFTrigger       ATLFTrigger     ATLFast trigger class  : 0
 TPaveText  X1= -0.980000 Y1=0.820000 X2=0.000000 Y2=0.980000 TPave
 OBJ: ATLFDisplay       ATLFDisplay     Utility class to display ATLAS
outline, tracks, clusters, jets,.. : 0

Check if you have read in the generated particles with:
root >  gATLFast->MCMaker()->Fruits()->ls()
