Hi all,
I'm using Jboss 3.0.4 w/ Tomcat 4.1.12, running Sun's JDK (build
1.4.0_01-b03), on Solaris 7. I have one ear file which contains a bunch
of local entity CMP 2.0 beans that access my database. I have a
separate ear file containing a session bean that looks the Entity beans
up via the global JNDI, and trys to use the local interface to do its
work.
The problem I'm encountering, is that if I redeploy the ear file
containing the entity beans without redeploying the ear containing the
session bean, when I go to retrieve my local interface via the following
code I get a ClassCastException:
private UserLocalHome getUserLocalHome()
throws NamingException
{
UserLocalHome home = null;
InitialContext ctx = new InitialContext();
try
{
home = (UserLocalHome)
PortableRemoteObject.narrow(
ctx.lookup("ejb/iaf/User"), UserLocalHome.class);
}
finally
{
ctx.close();
}
}
If I simply go and redeploy the ear containing the session bean after
that, everything works again. Is this supposed to happen and if so, can
somebody explain it. I know that class files have the notion of a
version, but the interface is really not changing at all between
redeployments, etc.
Also, I read on some jboss-user list archive of people experiencing
similar problems if the ear files contained jndi.properties files. I
have double-checked this and can assure you that neither of my .ear
files have this.
Thanks in advance for any help,
-Eric
