In the SpringCompMgr.java file, the sakai.home property is set as forward slashes. See the following lines:
// find a path to sakai files on the app server - if not set, set it
String path = System.getProperty("sakai.home");
if (path == null)
String catalina = getCatalina();
if (catalina != null)
What this causes to happen is for paths related to sakai.home on Windows, there is half backslashes and half forwardslashes in the URL. I am seeing this when trying to access TOMCAT_HOME\sakai[myfolder]\myfiles..
