What is the value of indicating success or failure, if the answer is only partially true? You can't know for certain whether the answer you have is meaningful, so it's useless. > Furthermore, if the application reports a successful start even though > it is not completely initialized, i consider this an application > fault, therefore not my concern.

That seems contradictory, but it's probably my misunderstanding.

Yes it will, using the same mechanism that the manager webapp uses; you can interact with Tomcat over JMX, the API gives you detailed information about applications. > [...] >> >> 'fullstart' is an odd name, people might start using it thinking that >> 'start' did not fully start the server. >> > > Which is the case in this particular scenario!
