I’d like to learn GWT, and I like the fact that it compiles to Javascript. My question is, how much of Java I can really use with GWT? My guess would be that limitations apply mostly for client side, while on the server side I should be able to make use of any existing Java library, right? Or, will I be only able to use a small subset , because of the compilation to Javascript thing?
What are it’s limitations? I am interested in what it’s not able to do, or things that require too many workarounds to implement. I need to know if learning GWT is a good choice for a possible freelance carrier in web development.
The GWT website has this documentation exactly to answer that question.
