Re: [Cobertura-devel] Issues using Tomcat

[Steve C. <sch...@gm...>]

Take look at the FAQ page (http://cobertura.sourceforge.net/faq.html) the
section about Using cobertura with web application. I have found that
deploying web applications, sometimes if it can't find the cobertura.ser
file it will generate the report on another part of the machine if you
never set -Dnet.sourceforge.cobertura.datafile=  for all the jvms. If you
want to verify, make sure while you're running your junits, open process
explorer and make sure that variable is being set.

Thanks,
Steve.
