-----BEGIN PGP SIGNED MESSAGE----- Hash: RIPEMD160 Hello, Gianny
can you point me to where to grab the new jar? I tried the download at codehaus.org but the file date for the 1.4 snapshot is July 2006?? And funnily I can't access the cvs (Could not connect to :pserver:[EMAIL PROTECTED]:/home/projects/tranql/scm: I/O exception occurred: Connection refused: /home/projects/tranql/scm: no such repository ).
