Chris,
Are we near a solution yet? Will this likely be a patch or a complete rebuild?
Thanks.

> I built Sakai 2.7.1 from source using Maven 2.2.1 and then installed same in Tomcat 5.5.31. The System runs on Redhat ES 5. I followed the install from source instructions on the Sakai Project website (URL: http://confluence.sakaiproject.org/display/DOC/Sakai+2.7), including setting java_opts within Tomcat, etc. I also tailored a sakai.properties file so as to include a proper URL and title. I assume that “By default, all Sakai distributions are configured to use an in-memory version of HSQLDB” means that I can leave database configuration alone at least until I’ve tested everything.

For the portfolio, I chose Simple HTML and added a page containing only the line “My Portfolio”. When I clicked on the link to view the portfolio, the response was “An unexpected error has occurred.” And along with that, a lengthy StackTrace (included below).
