I have done exactly that:
Ran the wizard-based installation, made sure that app was running and copied the apps to existing tomcat webapps directory.
I am running Apache 2.2, tomcat-connectors-1.2.23 (port 8009/ajp13), tomcat-5.5.23 (port 8080) and Oracle 10.1 on Fedora 7. I have several other apps using apache tomcat-connector and work properly.
The application installs properly and runs fine with the wizard-based installation and tomcat instance. When I copy the apps, konakartadmin runs fine, but when I run konakart, I get only the top bar (Home My Account | Cart Contents | Checkout and above content, plus just the title Categories and nothing underneath). When I look at the log files, I get whole lot of errors starting with:
