Re: [xwiki-users] Xwiki Enterprise 4.3 fails to start on Apache Geronimo 3.0

Hello I am interested in running Xwiki Enterprise using the WAR file on an Apache Geronimo 3.0 server. I have been trying to do so for about two weeks now but haven't been able to start Xwiki successfully I initially tried with Xwiki Enterprise 4.2 and then with 4.3 but with no success. Here are the steps that I have performed in my most recent attempt: 1) Installed a MySQL server, created an xwiki database, defined an xwiki user (with password xwiki), and granted the user all permissions to the database. I am able to successful connect to the xwiki database using a database client. 2) Downloaded and extracted the Apache Geronimo 3.0.0 ZIP file 3) Placed the dependency JAR files in the appropriate directories inside the Geronimo repository directory. 4) Created a geronimo-web.xml file and copied-and-pasted the complete sample file contents provided at http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationGeronimo. I updated the version numbers in geronimo-web.xml file to match the versions of the JAR files that I placed in the repository. 5) Defined a JDBC datasource in Geronimo using the procedure described in http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationGeronimo 6) Downloaded the XWiki 4.3 WAR file and deployed it on the Geronimo server (specifying the customized geronimo-web.xml file on the deployment page). The deployment was successful. 7) Modified the hibernate.cfg.xml file by commenting out the default database configuration and specifying the appropriate parameters for the MySQL database (which is what I'm using). 8) Copied the modified geronimo-web.xml file into Xwiki's WEB-INF folder. 9) When I tried to start the XWiki application, the following errors were generated in the log file:

Caused by: java.lang.ClassCastException: org.ops4j.pax.logging.slf4j.Slf4jLoggerFactory cannot be cast to ch.qos.logback.classic.LoggerContext at org.xwiki.logging.logback.internal.LogbackUtils.getLoggerContext(LogbackUtils.java:50) at org.xwiki.logging.logback.internal.LogbackUtils.getRootLogger(LogbackUtils.java:58) at org.xwiki.logging.logback.internal.LogbackEventGenerator.initialize(LogbackEventGenerator.java:96) at org.xwiki.component.embed.InitializableLifecycleHandler.handle(InitializableLifecycleHandler.java:39) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance(EmbeddableComponentManager.java:323) at org.xwiki.component.embed.EmbeddableComponentManager.getComponentInstance(EmbeddableComponentManager.java:378) at org.xwiki.component.embed.EmbeddableComponentManager.getInstanceMap(EmbeddableComponentManager.java:185)

There is mention of an Observation Manager component and SLF4J. I'm not sure what is preventing Xwiki Enterprise from starting correctly. Any assistance would be greatly appreciated. Thank you. Naoufel
