I finally found what the problem was. It seems that the undeploy I've done of the previous version (1.3.5) is not enough, so I deleted the content of the data directory (I precise that I was using Archiva only for testing, for now).
My conclusion is that it's better to start from a clean Tomcat installation. The repositories content and the databases (not the archiva database if upgrading to 1.4) must be saved before the reinstallation.

Hi, I just saw there was a new milestone version of Archiva. I've installed it following the user guide. Archiva is deployed but when I access the home page "Create admin user", I only see the upper part of the page (where there are the login and register links and the Search for textbox) but the rest is empty. I take a look at the log, and I see the following exception: Java.lang.NoClassDefFoundError: org/apache/maven/archiva/web/startup/ArchivaVersion The exception is repeated periodically ( I can see this in the log file). Thanks
