more examples of attaching scalive to JVM process

[zinking]

I felt this offers great help when we could hook into a running JVM. but I don't know the details.

what are the could be done ?

1. modify class/method definition?
2. fetch and update beans like in a spring jam?
3. more.

modify class/method definition?

No Scalive can't do that, because in order to do that you need to create classloaders. Currently Scalive simply uses the classloader in the target process.

You can still do that if your program is designed up front for that purpose. For example:

object O {
  var myFunction: MyInterface = defaultImplementation
}

Then later, in Scalive REPL console you set O.myFunction to point to another implementation.

fetch and update beans like in a spring jam?

I guess this is possible. But I'm not very familiar with Spring.
