Maybe you're in fact missing a jar then. Send a full stack trace.

Thanks for your help, but I don't have a WEB-INF/lib folder. All the hibernate
jars are located in shared/lib and my eclipse project links to them there. Are
copies or multiple versions of a class disallowed by the Tomcat classloader?
If not, what else could be causing the problem?
Thanks for your help,

Subject: Re: Weird NoClassDefFoundError
Classloading issues. You probably have the tapestry related jars (how
about the same annotations jar?) in your WEB-INF/lib.
I'd remove everything from shared/lib and keep the dependencies
application specific.

I am getting a weird NoClassDefFoundError when I try to start my application.
The error is thrown when I call new AnnotationConfiguration(). The code
compiles and hibernate-annotations.jar is in [tomcat-home]/shared/lib. Any
ideas? Below is the relevant code (I think).
Thanks for your help,

From Home.java:
public void pageBeginRender(PageEvent event)
{
System.out.println("ever here");
if (!getRequestCycle().isRewinding())
{
BugReport br = new BugReport();
User u = new User();
u.setUserName("foo");
u.setPassword("bar");
br.setSubmitter(u);
br.setAssignee(u);
getUserDAO().save(u);
getBugReportDAO().save(br);
}
System.out.println("ever here");
}
From userDAO.save():
public void save(Object o)
{
if (o != null)
{
getSession().saveOrUpdate(o);
}
}
From userDAO.getSession():
private Session getSession()
{
return sessionOwner.getSession();
}
sessionOwner is injected by HiveMind.
From sessionOwnerImpl.java:
public Session getSession()
{
if (session == null)
{
session = sessionCreator.getSession();
if (trans == null)
{
trans =
session.beginTransaction();
isToRollback = false;
}
}
return session;
}
sessionCreator is injected by HiveMind.
From SessionCreatorImpl.java:
public SessionCreatorImpl()
{
AnnotationConfiguration config = new
AnnotationConfiguration(); <-- the code blows up here
config.configure();
factory = config.buildSessionFactory();
}
