[Columba-devel] Re: jar file

[<jav...@gm...>]

Hi,

well as far as I understood the concept - and correct me if I am mistaken -
the jar files in the ext/ directory (such as log4j.jar) are EXTension
libraries, which are not necessarily needed or are taken from other projects and
don't quite belong to Columba. Therefore they are not integrated into the file
columba.jar but placed outside the archive. So if you delete those extra
files, of course Columba won't run properly (if it comes up at all). The Columba
Java Archive contains all those classes and resource files belonging to
Columba, no extra stuff. Therefore the manifest file contains a classpath entry
pointing to the ext/ directory. And furthermore this is the reason why Columba
is distributed as a .zip archive and not just as a .jar file, because the
compressed zip file contains the libraries in ext/.

Regards,
Michael
