Problems moving from JBoss 4.0.4GA to 4.0.5GA and Seam 1.0.1

[akearns1]

Prior to testing my application I built and deployed the seam booking example.

My running/deployed application under JBoss 4.0.4 GA uses
1) a base abstract class
2) a common class that extends from base class
3) multiple different classes that extend from common class each containing unqiue additional attributes for that class. The following is an attempt at specifing that heirarchy.

Abstract Class
@Entity
@Name("id")
@Table(name = "pro_id")
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class ProId implements Serializable {

Common Class
@Entity
@Name("device")
@Table(name = "device")
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class Deviceextends ProId implements Serializable {

Multiple Classes (Devices) with unique attributes
@Entity
@Name("deviceabc")
@Table(name = "device_abc")
public class DeviceAbc extends Device implements Serializable {

@Entity
@Name("devicedef")
@Table(name = "device_def")
public class DeviceDef extends Device implements Serializable {

When I attempt to deploy I get the following exception

I use the names DeviceAbc and Device in different xhtml in my client.

Can anyone explain what this error means? I found another posting for a similiar error, but that did not help.

Thanks

Don't put @Name on the abstract class

[akearns1]

To get my application to deploy I found I also had to change how I use @Name and @Role annotations. I had:

@Entity
@Name("device")
@Roles ({
@Role(name="device", scope=SESSION),
@Role(name="deviceToDelete", scope=CONVERSATION)
})

I had to change it to:
@Entity
@Name("device")
@Roles ({
@Role(name="deviceToDelete", scope=CONVERSATION)
})

Thanks.
