Scott,
I upgraded to jboss-3.0.4_tomcat-4.0.6, but I still have the exact same
problem. Everything works fine when I first start JBoss and deploy the
.ear, but as soon as I re-deploy the .ear, I get the ClassCastException.
This happens even when I remove the .jar and .ear files from the deploy
directory completely, then re-deploy them. Could this be a problem with my
web.xml and jboss-web.xml files, or is it unrelated? This strikes me as a
pretty serious problem -- see any solution?
The full error I am getting, if it helps, is:
java.lang.ClassCastException

Subject: [JBoss-user] ClassCastException on redeploy of .ear
Hello all,
Using jboss-3.0.0_tomcat-4.0.3, I am trying to access a Session bean =
called Registration from within a servlet, both of which are part of an =
application called pc, deployed as pc.ear. Here is the code I'm using =
to do it:
=20
Context jndiContext =3D getInitialContext();
Object ref =3D jndiContext.lookup("RegistrationHomeRemote");
RegistrationHomeRemote registrationHome =3D (RegistrationHomeRemote)
PortableRemoteObject.narrow(ref,RegistrationHomeRemote.class);=20
RegistrationRemote registration =3D registrationHome.create();=20
registration.remove();
=20
Everything works fine when I start jboss fresh and deploy the ear. =
However, as soon as I make a change to any file and re-deploy the ear, I =
get a ClassCastException at the third line. I'm totally stumped - why =
would it work on initial deployment, then stop working on =
re-deployment??? Any help would be most appreciated.
=20
My deployment configuration files are as follows:
=20
ejb.jar:
<session>
<display-name>Registration</display-name>=20
<ejb-name>Registration</ejb-name>=20
<home>com.pc.ejb.session.interfaces.RegistrationHomeRemote</home>
<remote>com.pc.ejb.session.interfaces.RegistrationRemote</remote>
<ejb-class>com.pc.ejb.session.beans.RegistrationBean</ejb-class>
<session-type>Stateful</session-type>
<transaction-type>Container</transaction-type>=20
</session>
jboss.xml:
<session>
<ejb-name>Registration</ejb-name>
<jndi-name>RegistrationHomeRemote</jndi-name>
</session>
web.xml:
<servlet>
<servlet-name>RegistrationServlet</servlet-name>
<servlet-class>com.pc.servlets.RegistrationServlet</servlet-class>
</servlet>
<ejb-ref>
<ejb-ref-name>Registration</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>RegistrationHomeRemote</home>
<remote>RegistrationRemote</remote>
<ejb-link>Registration</ejb-link>
</ejb-ref>
jboss-web.xml:
<ejb-ref>
<ejb-ref-name>Registration</ejb-ref-name>
<jndi-name>pc/RegistrationHomeRemote</jndi-name>
</ejb-ref>
