Hi, I read the Java policy, but I has not became more wise. Say, I have a complex application, which licensed under GPL v2. But it does not compile with free tools. The JVM is not a problem, as Debian has j2sdk1.4, but what's if the application needs SUN's JavaMail as well? What should I write to debian/control's Build-Depends field? libgnumail-java is not enough, as that misses some classes the application needs. Regards, Laszlo
