Hi,
About the spelling: the embedded tomcat service uses a class named
org.apache.tomcat.startup.EmbededTomcat, so I named it like that.
English is not my mother tongue, and obviously this goes for some apache
folks too :)
(for the record: in 4.0, they changed that to Embedded)
About TomcatService vs EmbededTS: the embedded service will allow you to
share the class loader between tomcat and jboss, so you can bypass the
rmi overhead for inVM calls, so you can save 3ms (out of 3.5ms!) per
call for servlet->ejb.

What is strange is that nothing has changed in TomcatService for the
last 7 weeks. Are you sure it worked before?
And anyway, jboss does not mess with tomcat classloaders in
TomcatService, so I'd say it's a tomcat bug.
