• Installieren Sie pro gewünschte MessageHandler Instanz einen sedex Client. Die Installation und Konfiguration mehrerer sedex Clients ist hier nicht beschrieben. Fahren Sie erst weiter, wenn jede der sedex Client Instanzen korrekt funktioniert.
• Sie brauchen pro MessageHandler Instanz ein separates Installationsverzeichnis (z.B. c:\mh-SEDEXID, wo SEDEXID die sedex ID des entsprechenden eSchKG Teilnehmers ist) und separate Arbeitsverzeichnisse.
• Passen Sie die Variablen wrapper.ntservice.name, wrapper.ntservice.displayname, wrapper.ntservice.description in der Datei conf/wrapper.conf jeder Instanz entsprechend Ihren Bedürfnissen an.
• Passen Sie den Port der Webservice Schnittstelle von Messagehandler in jeder Instanz an (Attribut /config/messageHandler/webserviceInterface/@port in der Datei conf/config.xml). Jede Instanz braucht einen eigenen Port, sonst kann der Messagehandler den Webservice nicht starten.

How to upgrade a MH installation on Windows

If you installed MH using the MSI installer, be aware, that the installer always performs a completely new installation. It is not conceive to perform an upgrade! So back-up your MH configuration before installing the new version.

To upgrade:

• Stop the MH service.
• Backup at least the directories listed below. Recommended: backup the whole server before proceeding.
• Uninstall the older version.
• Install the new version. During the installation process, you must list the same directories that the previous installation referenced (sedex directory, etc.)

The MH configuration file config.xml lists all the directories and files to back up. The XML elements referencing the directories to back up are:

• /config/messageHandler/workingDir
• /config/messageHandler/statusDatabase

Is MessageHandler affected by "Log4Shell" vulnerability?

Although MessageHandler uses the log4j software library, MessageHandler is not affected by the vulnerability. The reason is that MessageHandler uses an older version of log4j, which is not vulnerable.

Please note that the sedex client, with which MessageHandler work together, is also not vulnerable in versions > 5.0.
