The page "Getting_started_with_LotusScript" has been deleted by JoanTouzet: https://wiki.apache.org/couchdb/Getting_started_with_LotusScript?action=diff&rev1=3&rev2=4 Comment: https://cwiki.apache.org/confluence/display/COUCHDB/LotusScript - <<Include(EditTheWiki)>> - ## page was renamed from Getting Started With LotusScript - ## page was renamed from GettingStartedLotusScript - Getting started with !LotusScript and the CouchDB API. - - This is an example of wrapper classes that use LS2J to send requests to a CouchDB server from !LotusScript. This could be useful to move data between Domino databases and CouchDB databases. The !LotusScript code roughly tracks the structure of the Ruby code. - - == Basic API == - - {{{ - Option Public - Uselsx "*javacon" - }}} - - {{{ - Sub Initialize - %REM - LotusScript LS2J classes for CouchDb - Copyright (C) 2006 Alan Bell - Dominux Consulting - - This program is free software; you can redistribute it and/or - modify it under the terms of the GNU General Public License - as published by the Free Software Foundation; either version 2 - of the License, or (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
