tomcat won't start

Steps taken

• extracted xwiki-web-standard-1.1.2.war in /usr/share/tomcat5/webapps/xwiki
• http://www.xwiki.org/xwiki/bin/view/AdminGuide/InstallationTomcat mentions an issue with the java security manager. I searched all files in $CATALINA_HOME and /etc, but none of them contained a string TOMCAT5_SECURITY
  I found Stefan's suggestion on http://jira.xwiki.org/jira/browse/XWIKI-348, and as there isn't a /etc/tomcat5.5/policy.d/ directory, I edited /etc/tomcat5/catalina.policy and added these lines at the bottom:

// These permissions apply to xwiki
grant codeBase "file:${catalina.base}/webapps/xwiki/-" {
permission java.security.AllPermission;
};

• found the remark stating that "If you are installing in a linux/unix environment you have to setup the xwiki.upload.tempdir parameter as explained in the JIRA entry (http://jira.xwiki.org/jira/browse/XWIKI-530) before importing anything into XWiki.", but I couldn't find where I should define this parameter. As it only comes into play when you need to upload larger files, I decided to go ahead for the time being

• set up mysql as per http://www.xwiki.org/xwiki/bin/view/AdminGuide/InstallationMySQL
• the mysql database tests ok
• connector file = http://www.mysql.com/products/connector/j/mysql-connector-java-5.1.5.tar.gz
• WEB-INF/hibernate.cfg.xml already had an entry for mysql that could be uncommented, and I started off with that one.
• verified that xwiki.cfg has a xwiki.store.hibernate.path=/WEB-INF/hibernate.cfg.xml entry

when I start tomcat, catalina.out reports:

Does anyone have an idea what went wrong?

Kind regards,
