Hello, hope you're fine. I am an experienced and enthusiastic java developer and am interested in working with you on this project. Can you share a bit more details about the backend part corresponding to which the front end training is required e.g. what kind of applications do you have? JSP/JSF, Soap based web services, Restful APIs, Spring, Play framework etc.?
Secondly, I hope you're clear about the difference between java and JavaScript. Front end development is mostly done using html, css and javascript. The challenging part is the integration of front end and backend code. This can be done in multiple ways. In case you are interested we can discuss the course outline further.
Hoping to hear a positive response from you.
