Kalau anda menemukan error seperti yang saya temukan seperti ini:
12:38:51,328 FATAL [DefaultServerContextBuilder] Error initializing ServerContext because this is not a DWR thread and there is more than one DWR servlet in the current classloader.
12:38:51,328 FATAL [DefaultServerContextBuilder] This probably means that either DWR has not been properly initialized (in which case you should delay the current action until it has)
12:38:51,328 FATAL [DefaultServerContextBuilder] or that there is more than 1 DWR servlet is configured in this classloader, in which case you should provide a ServletContext to the get() yourself.
12:38:51,328 WARN [CallCenter] Random event failure
Itu disebabkan adanya dua configurasi untuk dwr. Waktu itu saya membuat sebuah website dengan server jBoss dan mendeploy website yg q buat plus dwr sample project. Saat itu dwr sample saya letakkan di folder deploy jboss dan website q deploy dari myeclipse. dan ternyata muncullah error sprti diatas, solusinya tinggal undeploy(hapus) project dwr sample atau pindahkan ke application server yg berbeda agar tidak terdeteksi dua dwr configurasi.
