I have recently ported my application from Jboss 7 to WildFly 8.0.0. I have a load balancer setup in apache upfront to Wildfly which is using mod_jk connector. Every thing is working except webservice when called from a dot net environment. I have the same issue reported herein Problem with web service. But I would like to know is there any other solution other than configuring mod_cluster. Anyone have an idea?
