From: Roland Häder Date: Thu, 25 Aug 2016 10:34:53 +0000 (+0200) Subject: Please cherry-pick: (be careful with project-specific names!) X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=d50abde26bb59a78246e9c2a7c6873bc14b513fb;p=pizzaservice-ejb.git Please cherry-pick: (be careful with project-specific names!) - UserActivitySessionBean should better extend BaseDatabaseBean as no mail is being sent from this type of EJB - added activity JMS queue - implemented it in message-driven bean - this whole thing may be shortened to only the EJB but then it is synchronous and people then will experience a slow down on heavy load Signed-off-by: Roland Häder --- diff --git a/src/java/org/mxchange/jusercore/model/user/activity/LandingUserActivityLogMessageBean.java b/src/java/org/mxchange/jusercore/model/user/activity/LandingUserActivityLogMessageBean.java deleted file mode 100644 index c4a865b..0000000 --- a/src/java/org/mxchange/jusercore/model/user/activity/LandingUserActivityLogMessageBean.java +++ /dev/null @@ -1,104 +0,0 @@ -/* - * Copyright (C) 2016 Cho-Time GmbH - * - * This program is free software: you can redistribute it and/or modify - * it under the terms of the GNU Affero General Public License as - * published by the Free Software Foundation, either version 3 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.
