Re: Some newbie questions
1. how can i know which jres are installed on my PC (Windows)?
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
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
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.
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?
BTW - Please start sentences with a single upper-case
letter, and note that the word 'I' is always upper-case in
