I hope this is the right subforum to post this.
I'm very new to maven, vaadin and java applications in general, so I hoped you could help me with this as I'm not sure what's the best way to go about it.
What I want to do now is to access that data sent through ajax (the string containing the data of the uploaded file) in Java because I need to run it through some validation.
I had a good look around, including the book of vaadin, and the net in general and considering that I have never done this before, it seems that one way could be to have a connector, but it looks a little too complicated and also it appears - from what I understand from the book of vaadin https://vaadin.com/docs/-/part/framework/gwt/gwt-overview.html - that I won't be able to implement that in my project given the structure I have - which is different from what's in there.
So, my question to you guys is, given the project I have (just a normal maven project) what would be the easiest way for me to access this data from Java?
Here is some code from the project, to put things into context:
