Unable to use night build [message #20913]

Hi all. I'm an italian student trying to port an existing project based on
Eclipse plugins onto mobile devices.
I've founded the MTJ project and downloaded the N20080430 nightly build.
I've installed a fresh Eclipse 3.3.2 and succesfully installed the MTJ
runtime plugins and future, but when I try to create a new "Midlet
Project" or "Java ME Midlet" I obtain the following error messages:
1) trying to create new "Midlet Project" ---> Plugin org.eclipse.mtj.ui
was unable ti load class
org.eclipse.mtj.ui.internal.wizards.NewJ2MEProjectWizard
2) trying to create new "Java ME Midlet" ---> Plugin org.eclipse.mtj.ui
was unable ti load class
org.eclipse.mtj.ui.internal.wizards.NewMidletWizard.

It seems that some classes are not present in the downloaded plugin and
futures.
It's a strange thing, and the two error messages seems to be "switched".

I'm also experience some trouble trying to configure preferences. If I
open the menu Windows-->Preferences and select any of the "Mobile Tools
for Java" preferences page I alway get this error message "Unable to
create the selected preference page.Reason :
org/eclipse/mtj/ui/internal/preferences/xxxPage (Unsupported major.minor
version 49.0)" where xxx is the name of the preference page I'm trying to
select.

I know this kind of error is related to installed and used JRE, but I'm
using Java 6 Update 6 Sdk and properly configured preferences for compiler
(don't know if this can help).

What's my error? Do I need to download something else? I extracted the
jar plugins and I can't find org.eclipse.mtj.ui.internal package...

Any suggest will be very appreciate, thank you so much.

(Please, sorry for my poor English :) )

NewMidletWizard.class... I don't understand.

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.
