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:

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.
