I'm attempting to upgrade from jira 4.1.2 to 4.4.6. Right now, I just want to run 4.4.6 as a standalone out-of-the-box. However, when I go to the home page, the first thing I get is a NoClassDefFoundError: com/atlassian/jira/web/util/ProductVersionDataBeanProvider.
Like I said, I'm running this straight out of the box. What could be missing? To deploy, I downloaded the war.zip and copied the webapp directory to my Tomcat webapps dir, just as I do with 4.1.2.
Thanks for any input!
