Do I have to study JavaSE before write an application in JavaEE

[LongTTH]

Hi everybody, I'm an newbie in Java world. In fact, I'm a C/C++ developer (at student level), but as some error in my school's schedule, I have to write a JavaEE application in 3 months from now (this app is small (of course), but will be widen sometimes (in my next semester). So I don't have time to learn both of them by roster. (step by step as usual)
So, to you pros, I have that question (on title):
When I have some basic knowledge on Java (keyword, syntax, code convention, etc...)
Do I have to study JavaSE before writing an application in JavaEE?
Because when I search for JavaEE example, the authors almost write examples to who has learned JavaSE.

java - JSE vs J2EE, college and career - Stack Overflow

^That thread has some pretty good descriptions about the differences. One good analogy I saw there was java se is like learning to drive a car, while ee is like learning to drive an 18 wheeler. I honestly don't have experience with ee, but from reading on there it sounds like you want to understand the basics. What kind of application are you expected to write?

Yep.
You need to understand the basics of Java, which would be a fair amount of SE, because otherwise you're likely to make some pretty silly mistakes which will make writing a Java EE app so much harder.
