Re: [Springframework-developer] Orion 2.0.2

[Peter d. H. <pe...@de...>]

We found another Orion 2.0.2 bug recently: when deploying two Spring-based
webapps on the same Orion server, we got into major classloading issues
where loaded in one application would end up in the other.

The problem turned out to be that, Orion does not seem to correctly set the
Thread context classloader for the second and subsequent webapps that it
initialises. Because Spring uses the context classloader throughout this
means that any class loaded by name during Spring initialisation will get
loaded from the wrong webapp. Oops.

We ended up creating a version of
org.springframework.web.context.ContextLoaderServlet with one extra line in
init():


Thread.currentThread().setContextClassLoader(getClass().getClassLoader());

Suddenly all our problems disappeared.
