Java library/java interface or wrapper methods for gpg/GnuPG

[Ralf Hauser]

Hi,

>From a standard tomcat - struts - MySQL web application, we would like to
send gpg encrypted / signed e-mails. The public keys will most likely be
held in the relational database on a per recipient basis.

Are there any Java interfaces to gpg like http://www.bouncycastle.org/ for
S/MIME?

Or should http://www.gnupg.org/(en)/related_software/gpgme/index.html.en be
used ?

Or is system exits as sought in
http://marc.theaimsgroup.com/?l=gnupg-users&m=105820324708386&w=2 the way to
go?

Any hints would be highly appreciated

	Ralf
