You may sell GPL-based software, but you must sell it with the
source code.
... and you must not forbid giving that source code away (on GPL
basis).
is that mean someone can build a executable file from my sources ?
or if i just provide part of my sources that related to jabberpalm
library only ?
That means you must give away all of your source under the GPL to
anyone you give the binaries to. If the Jabberpalm code you're using
is GPLd, your client is a derivative work of Jabberpalm and as such
must also be GPLd.
This does not prohibit you from charging for your binaries, it does
mean that anyone who has your binaries is entitled to the source, and
is then free to do almost (read the GPL for details) anything they
want with it, including redistributing it.
There is absolutely nothing to prevent you distributing it with a
shareware notice asking people to pay you for it though, although
obviously someone with the source could remove such a notice and
redistribute.
