getOutputStream and getWriter in servlet

[John Smith]

In a servlet you can call either getOutputStream or getWriter but only one,
calling the other later gets an IllegalStateException. Is there a way of
finding out what has already been called?

Thanks

calling the other later

Just don't do it.

the best solution is to know what you call. There is no point in writing
binary data to a writer. I would say this is also the meaning of the
exception.

Besides that, I'm afraid the only possibility to know that a method has
been called is to catch the exception when you try to call the other one.
