Confluence Menus Do Not Work, or Confluence Fails to Start when Running in the Same Application Server as JIRA 4.0, 4.0.1 or Crowd 2.0.x
Symptoms
Confluence starts up but, amongst other things, the menus and the editor don't work. The log file will show the following stacktrace:
2009-12-04 11:29:34,696 FelixStartLevel ERROR [extender.internal.activator.ContextLoaderListener] Unable to process extender configuration
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from OSGi resource[bundle://3.0:0/META-INF/spring/extender/spring-event-bridge.xml|bnd.id=3|bnd.sym=org.springframework.osgi.extender]; nested exception is java.io.IOException: No framework context found
at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:349)
...
Caused by: java.io.IOException: No framework context found
at org.apache.felix.framework.URLHandlersBundleStreamHandler.openConnection(URLHandlersBundleStreamHandler.java:69)
Cause
This is caused by JIRA 4.0.x or Crowd 2.0.x and Confluence 3.1.x running in the same Java Virtual Machine (ie. Application Server). It's due to the fact that Confluence 3.1 uses a newer version of Atlassian Plugins which brings a newer version of Apache Felix (2.0.1) with it. This version of Felix is not compatible with the the version of Felix JIRA 4.0 or Crowd 2.0.x provides (1.2.1) if both versions run in the same Java VM.
Please ensure that you are not running multiple Atlassian applications in a single Tomcat container. See this FAQ for more information.
Resolution
See Unable to Start JIRA when Running with Confluence or Crowd in the Same Application Server Container for a solution.
