Openfire Cluster sorunu

Merhaba,

Ayrı ayrı iki Windows 2008 R2 server üzerine Openfire 3.7.1 kurdum. Java Version 6 update 30 (build 1.6.0_24-b07) yükledim. Her iki makine aynı veritabanını (SQL Server 2008) kullanıyor.

Bu iki makineyi cluster yapabilmek için Clustering Plugin 1.2.0'i kurdum ve C:\Program Files (x86)\Openfire\lib dizinine söz konusu plugin için gerekli olan coherence-work, coherence ve tongosol dosyalarını kopyaladım.

Serverı kapatıp tekrar açtığımda aşağıdaki hatayı aldım. Sorunun çözümü için yardımcı olabilirseniz çok sevinirim. Şimdiden teşekkürler, iyi çalışmalar...
