<div dir="ltr">Thanks ! But in fact, I read <a href="http://docs.plt-scheme.org/web-server/index.html">http://docs.plt-scheme.org/web-server/index.html</a> and it seems interesting. Now, I decided to use JScheme. As I said to Shriram, it is an interpreter Scheme one can use in java. Simply write : JScheme myScheme =new JScheme(); system.out.println( myScheme.eval("(+ 1 2)").toString()); And I don't know if I am going to code my entire application in Scheme as it said in <a href="http://docs.plt-scheme.org/web-server/index.html">http://docs.plt-scheme.org/web-server/index.html</a> ("can be used to develop Web applications in Scheme."). For the GUI, I prefer to use a object oriented language. For the engine, I prefer a functionnal language where data and programs have the same structures. Any way, thanks for your answers. I will try to convince the computer science department of my university to teach Scheme and to use DrScheme, because... Scheme is a work of art.
