How to change JVM options from a running JVM

Question

Hello, I have to launch a remote application on my machine. I managed to do that with code that invokes the main method of the application I want to execute. What I do is to launch an instance of the class containing main function, here is an extract of the code:
Object obj = ....; //obj is the class containg main, for instance MyClass
java.lan.reflect.Method m = .....; //m is the main method
Object result = m.invoke(obj, args);This works, the main method gets called and so the application starts. Of course, the main method is called from a jar built in the right way.
But the way the main method gets called is like doing
java MyClassNow I have the problem to launch this application with some options to java command (these options are about remote debugging with JDI ).
In other words, what I would like to dis the following, if I could do it from command line:
java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket myApp.jar (myApp.jar is on a remote host)
while all that I'm able to do is
java myApp.jarOf course I want to do it from my java code, not from command line.
Thank you

It isn't possible as stated.
You must change the way that you are launching the VM. Either by providing options or by providing a different way to launch it.
