Additional characters from my gnujsp pages !!

Additional characters.
===============

I use apache1.3.9, jserv1.1.2 and gnujsp 1.0.1

When my jsp pages become text/html there are additional characters
at the beginning and the end of the same ones.
These additional characters that I can observe in the Browser (the
client)
are carriage return and other blanks that lack importance in text html,
but
that they are important in another text type.
If what I want is to return to the client text/plain or text/myownformat

(using the method setContentType ("text/plain") of the object request)
 then these additional characters ruin the response.

But,  I don't write these characters in my jsp pages .. :-(

How can it avoid the appearance of this characters?
Does reason appear these additional characters?
Are the jsp directives ?

On the other hand: Is the new version of the gnujsp clever?

Thanks in advance.
