Today I enabled SSI (Server Side Includes) on Tomcat so that I could use them with an unrelated we site that is on the same Tomcat server as Alfresco 3 Stable CE. When I did so it caused a bunch of problems which appear to be related to the default class loader that Tomcat uses depending on if SSI is enabled or not. Enabling SSI caused all of my extensions to stop working. I had changed some properties (in tomcat\shared\alfresco\extension) so that I can use an oracle DB and all of them were ignored and were using the default properties (in webapps\alfresco\WEB-INF\classes\alfresco). Any idea how I can fix this without modifying the original files in webapps\alfresco\WEB-INF\classes\alfesco?
