I thought that the *.nocache.js was being generated by the code
server, or when I explicitly compile the code.

It is being generated by DevMode when you launch it (which explains why the -war argument is mandatory even with -noserver), unless it already exists (unless it's older than the gwt-dev.jar, maybe, can't remember the details for sure).

...and by Compiler, of course, unconditionally.

When generated by DevMode, it only contains the code that's necessary to launch DevMode.

In any case, it contains nothing related to your Java code, everything comes from the *.gwt.xml files; with the exception of the permutation IDs (names of the *.cache.html/js files when you compile your app).

 

Does that mean that if I am using tomcat to host the GWT page I have to run the compile manually every time
I try to run the application.

Fortunately not!

If you can point DevMode's -war to the folder where Tomcat reads the files (exploded web app), then you don't need to compile your app, not even once.

Otherwise, you'll have to compile the app once (or launch DevMode once and then deploy the generated *.nocache.js file)

Really, compile once in -style PRETTY to have a look at what it looks like and how it works.
