Inprise said that maybe Delphi 5 can compile VCL source code into Java applet, that's already very exiting, but seems far from what you need.^_^

Yes, you can, at least sort of.
What you need is microsofts scripting ocx(msscript.ocx) and at least the ms javascript dlls
(www.microsoft.com/scripting).

Here's some basic code on how to use this:

procedure Tform1.runscript;
var
  script:iscriptcontrol;
begin
  Script:=CreateComObject(class_scriptcontrol) as iscriptcontrol;
  Script.SitehWnd:=self.handle;
  Script.Language:='JScript';
  Script.AddCode(widestring(Richedit1.lines.text));
  Script.run;
end;

If you need to script DELPHI itself, I can recommend the scripting engine by dreamcompany, its even better and you can script DELPHI functions from within Javascript.

Oh, I forgot to mention, that you can register your own automation serverobjects( written in delphi, ofcourse) to the scripting engine, so you can script them from javascript as well.

Goto 'scriptcontrol' (In de left pain)
Fill in the form, and you'll get it.
It's free by the way. And free to distribute provided a mention in your programs aboutbox and a bit of other legal stuff.
If you don't have ie4 then you must download the scripting engine as well, (Under 'Jscript', then 'Download') version 3.1!
version 5 is a bit buggy.

First, make shure the ocx is registered.
Then, create a form with a richedit or memo control.
You should be able to use the code I provided rightaway.
Write some Java code in the memocontrol, hit button to execute the code. I have more advanced code, just email me for a more elaborate example thaddy@cyco.nl
