Using gwt to change java files

[mehdi benchoufi]

I am really new to gwt but I have already posted a question and I
don't really understand.

I am working on a project that had already been developed. This
project uses get and the javascript comes from java files. I wanted to
make some changes on one of these java files. SO I was told I needed
to download get. This is what I did.

But my php and html files are processed with MAMP.

So now, how do I change the java files ? Where do I put my php and
html files to run it on my local server MAMP ? Am I supposed to take
the only java files, opening a "WebApp" (as indicated in the get doc),
runn it (with an ant build command ?), retrieving some files and put
those in my MAMP workspace ?

(I have read the gwt, but I didn't really understand it. I apologize
by advance if my question seems too simple)

Thanks, Mehdi

This project uses get and the javascript comes from java files. 

What do you mean exactly by "get" ? 

And what do you mean that javascript comes from java ? Do you mean java files compiled by a gwt compiler to javascripts or what ?

Could you provide some more details, because your questions looks absolutely abmigous!
