components.xml is read twice if the jboss-seam.jar is declared in application.xml as well as in manifest classpath ------------------------------------------------------------------------------------------------------------------ Key: JBSEAM-3481 URL: https://jira.jboss.org/jira/browse/JBSEAM-3481 Project: Seam Issue Type: Bug Components: Core Affects Versions: 2.1.0.BETA1 Reporter: Jay Balunas Assignee: Pete Muir Fix For: 2.1.0.GA Attachments: jsf-api.jar, jsf-impl.jar This issue was exposed while working on JBSEAM-3363, and using patched jsf jars from Ryan Lubke which fixes the initial problem (see note below on using Ryan's patch). We do not see the duplicate seam phase listener issue any longer, but we continue to see this error. 08:50:53,573 ERROR [[/Stantest]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener java.lang.IllegalStateException: duplicate factory for: org.jboss.seam.web.webSession (duplicate is specified in components.xml) at org.jboss.seam.core.Init.checkDuplicateFactoryExpressions(Init.java:222) at org.jboss.seam.core.Init.checkDuplicateFactory(Init.java:215) at org.jboss.seam.core.Init.addFactoryValueExpression(Init.java:278) This is because we are reading in the components.xml file from the jboss-seam.jar twice as this log shows: 2008-09-30 10:21:08,245 INFO [org.jboss.seam.init.Initialization] reading /WEB-INF/components.xml 2008-09-30 10:21:08,396 INFO [org.jboss.seam.init.Initialization] reading jar:file:/jboss/apps/jboss-4.2.3.GA/server/default/deploy/Stantest.ear/jboss-seam.jar!/META-INF/components.xml 2008-09-30 10:21:08,400 INFO [org.jboss.seam.init.Initialization] reading jar:file:/jboss/apps/jboss-4.2.3.GA/server/default/tmp/deploy/tmp3645jboss-seam.jar!/META-INF/components.xml To use Ryan's patch: ---------------------- Use the attached jsf jars in the jsf-libs directory, and update JBOSS_HOME/server/default/deploy/jboss-web.deployer/conf/web.xml to include the following context param: <context-param> <param-name>com.sun.faces.duplicateJARPattern</param-name> <param-value>^tmp\d+(\S*\.jar)</param-value> </context-param>
