I have an application which uses struts+spring+Hibernate . When I try to redeploy this application with change web.xml without restarting JBoss, then get the errors below. [org.springframework.web.context.ContextLoader] Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.hibernate.cache.CacheException: net.sf.ehcache.CacheException: Cannot configure CacheManager: null org.hibernate.cache.CacheException: net.sf.ehcache.CacheException: Cannot configure CacheManager: null how to solve this problem? Any help in resolving the hot deployment issue is greatly appreciated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3998870#...
