java compiler in JVM

[Wats]

Does anybody know of a java compiler that runs inside the JVM. I want to be
able to compile java source code on the fly without going to the system to
compile.

Thanks...

Just invoke the java compiler from within your JVM. It's written in
java and resides in tool(s?).jar which is installed in the JRE.

Here's a how-to:

javac itself is written in Java. More compilers, some in Java, are

linked to at <http://www.geocities.com/marcoschmidt.geo/jcomp.html>.

My anti-virus freaked on a javascript on your site, complaining about:
"The Trojan horse TR/KarmaHotel.A.4"

This is the first time I get this kind of warning while visiting a
website...

Isn't it just? I've wanted to have a good reason to play with that kind
of functionality for a while, but I haven't really got a good one yet )

The only thing I can think of is some kind of scripting engine... I don't
know what I would want one for (just yet).... oooh... I got it... How about
like in some kind of text editor... like M$ word/excel/etc does with VBA. It
would be neat to allow custom "wizards" along with a template... I guess I'm
going to have to write a text editor now... damn.

a project that could make use of online conciliations is a
spreadsheet. You generate the byte code or Java to compute the sheet,
using many threads. It would be far faster than interpreted Excel.
Even faster if you ran the sheet on a server with multicpus and just
posted the results back. The Athena project was almost there when it
ran out of money to further development.

Another similar project would be a regex engine where you generate
code for the regex on the fly, either is byte code or in Java and
compile it.
