How to invoke a wizard (and pass some parameters to it) after the completion of another wizard ?
If so, the last page of you first first simply needs to return the firstpage of the second wizard when asked (getNextPage()). Note, you'll need
to create an instance of the second wizard and call addPages() on it
once (and only once).

How do I instantiate a class from the runtime workspace?
You shouldn't. It would be very dangerous if you did this, since the class would run code in the same VM that Eclipse is running in. Imagine what would happen if it has a static initializer that does a System.exit(0)!
Usually people want to do this so that they can use reflection to find out information about the class. The org.eclipse.jdt.core package already provides a rich set of APIs to do this without loading the class, or running any untrusted code in the IDE. See How do I get access to some java information to get you started.
How do I programmatically, create a class, set it's superclass, add a constructor and a method, then "Organize Imports", format the source, and write out the resulting .java file?
