Hi All, I have been working through removal of conflicting class loading issues (same class loaded in a JAR in the WEB-INF, as in /common/lib or otherwise) however I am now getting the following issue and so far, I havent been able to determine a path around it: ----- 2011-08-01 08:40:25,595 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/xwiki]] (main) Exception sending context initialized event to listener instance of class org.xwiki.container.servlet.XWikiServletContextListener java.lang.RuntimeException: Failed to find the Observation Manager component at org.xwiki.container.servlet.XWikiServletContextListener.contextInitialized(XWikiServletContextListener.java:81) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3910) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4393) ............ ----- For the JARs I have had to move so far (in order): 1. xercesImpl-2.8.1.jar 2. logback-classic-0.9.29.jar 3. slf4j-api-1.6.1.jar Thanks in advance!
