Problem with "Double Isolation" configured for webapps ------------------------------------------------------ Key: JBAS-4534 URL: http://jira.jboss.com/jira/browse/JBAS-4534 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: ClassLoading Affects Versions: JBossAS-4.2.1.GA Reporter: Adrian Brock Assigned To: Adrian Brock A customer has reported a problem where configuring "double isolation" for web-apps causes problems. By "double isolation" I mean JBoss is already configured to provide servlet spec style isolation (parent delegation is false), but then the webapp configures it again in jboss-web.xml <class-loading java2ClassLoadingCompliance="false"> <loader-repository> xxx:loader=yyy <loader-repository-config>java2ParentDelegation=false</loader-repository-config> </loader-repository> </class-loading> This at least causes problems when initializing a servlet context listener, e.g with the Spring context listener 2007-07-10 12:47:04,078 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/context]] Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener java.lang.NoClassDefFoundError: java/util/Set at org.springframework.core.io.ClassPathResource.<init>(ClassPathResource.java:95) at org.springframework.web.context.ContextLoader.<clinit>(ContextLoader.java:133) at org.springframework.web.context.ContextLoaderListener.createContextLoader(ContextLoaderListener.java:57) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:48)
