[Building Sakai] Problem in sakai tool development

[John Bush]

or there is something  wrong with the tool.  A quick trick is to touch
the web.xml of the tool in question and tail the tomcat log while
tomcat is running.  This will cause the web app to recycle and you
should see the error right away, sometimes easier that digging through
all the startup output.
