We've been trying to combine two long-running applications of ours into a single application. The applications use Hibernate 3, ehcache 1.2, and Spring Framework 1.2.5.
The combined application starts out just fine, but when a user moves from the "first" application to a page from the "second" application a few things happen in quick sequence. The first and probably root issue is that the SessionFactory closes:
Code:
2010-01-27 11:28:46,602 INFO [org.hibernate.impl.SessionFactoryImpl] - <closing>
This in turn seems to kill ehcache since visiting any other page produces an error about the cache not being alive:
Code:
2010-01-26 17:55:43,211 ERROR [...] - <java.lang.IllegalStateException: The
STATIC_CACHE Cache is not alive.>
2010-01-26 17:55:51,572 ERROR [org.springframework.web.servlet.DispatcherServlet] - <Could not complete request>
java.lang.IllegalStateException: The DATASHEET_CACHE Cache is not alive.

I've been looking over this for days and just can't see what I'm missing. Is there a conflict between the two applications or is there some final connection I forgot to make?
