It's nowhere near as easy as it is in Perl.
If you look at JDBC you'll see that there's a call to Class.forName()
to load the driver class. That may be of use to you. It's sort of an
'import' on the fly.

Look up "Javassist" on google. Its what JBoss 4.0 uses to do dynamic aspect
weaving and dynamic remote proxy generation among other things. By the way,
for those who have used cglib, can you point toward some good online docs?
I have been unable to find any I found adequate. Javassist has pretty good
docs however.

If it's truly self-modifying, good luck debugging it.

the simple answer is "you can't"...self modifying code hasn't really been
feasible since the fortran 4 days...or maybe in C but that is still
platform dependent.

I recall the capacity of LISP-like functional languages (ie, Scheme)
to dynamically generate new functions and apply them.
It was a long time ago when I sat in that class, however, and I've
never used such a language outside of the classroom.

Java "modifies itself" every time it loads a new class
definition. An important point is that the decision to load
a class is made at run time, not at a "link time."
A Java program can even generate an array of bytecodes
at run time, turn them into a class, and create objects of
that class; see defineClass() in java.lang.Class Loader.

Hi all,
when I was young I programmed in an interpreted language that allowed
to modify itself.
Also Python can (writing and running a module, in-line):
fNew =open("newModule.py",'w')
lNew=
fNew.writelines(lNew)
fNew.close()

Ok, we are all aware of the situation where modifying the folder
structure (adding files, folders, deleting files, etc) will result in
ASP.NET triggering a recompilation/restart of the application.
In a nutshell, I understand how this can be considered desireable by
some, but I am not one of those people.
My situation is that we have a root site (hosted @ http://www.mydomain.com)

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
