Thanks for the help. Sorry for late answer. I was having some problems getting my messages to the list and just now I saw it was working again... Jae Gangemi sent me some explanations about how to get them working. I have to have the class used by both ears in the flat visibility as you are saying too. The client is in fact using the ear2 which is using as a client the ear1. The ear1 is holding components which will be used by more than one ear appication and so I decided to put them in a separate ear.

In that case just put your common jar file inside the server/lib directory but you loose the re-deploy ability for that jar.

RE: [JBoss-user] Two ears and classcastexception :( please, help!!
if you want to have two scoped ears in the same VM communicate w/ each other, then you need to extract the common interfaces out of both of the scoped ears and either deploy them as standalone jars, or package them up into an *unscoped* ear. ie: A.ear is scoped and exposes it's interface via a class called Foo. B.ear is scoped and needs to use interface Foo to access A.ear remove class Foo from both A.ear and B.ear and either deploy it in a standalone jar or repackage it up in the unscoped ear and you'll be good to go. the whiteboard picture would look something like this: Foo.jar or Foo.ear (unscoped) A.ear (scoped) B.ear (scoped) so when A.ear asks for interface Foo, it sees that it is not available via it's classloader and then asks for it from the top level class loader. the same thing occurs w/ B.ear - it can't find the class, and asks the top level loader, leaving both ears to get the same class loader definition. this also now allows you to hot deploy A.ear and/or B.ear w/o having to restart jboss. -jae -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Francisco Figueiredo Jr. Sent: Monday, January 26, 2004 2:22 PM To: [EMAIL PROTECTED] Subject: [JBoss-user] Two ears and classcastexception :( please, help!!
