I've been messing around a little bit with clustering by following the directions for clustering configuration for jetty[1] but modifying the instructions to work with tomcat. I've found that the sample app linked in the example deploys succesfully on the 2.1.1 release but not on the latest branches/2.1. A class cast exception is received when attempting to deploy the app[2]. It seems that 2.1.1 uses a milestone release of 2.0 rather than the full released version. I updated 2.1.1 locally to use the full 2.0 release of wadi, and that resulted in the same error I was seeing on branches/2.1. Anybody have any thoughts on what could cause this or how to fix it?
