I have managed to get serialization working across the bus with a one-step annotated process. Now you can expose entities to the bus, which will auto-generate demarshalling stubs in the client which allow full Java classes to be used within the bus API. For example: @Entity @ExposeEntity public class User implements Serializable { @Id private String userId; private String name; private String fullname; private String password; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getFullname() { return fullname; } public void setFullname(String fullname) { this.fullname = fullname; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } @Override public String toString() { return "userId=" + userId + ";name=" + name + ";fullname=" + fullname; } } The @ExposeEntity annotation tells Errai it should generate stubs to support it across the bus. You can then send it across the wire using the standard bus API like magic: @Service public class UserManagement implements MessageCallback { private MessageBus bus; @Inject public UserManagement(MessageBus bus) { this.bus = bus; } public void callback(CommandMessage message) { User user = new User(); user.setName("jdoe"); user.setFullname("John Doe"); user.setUserId("0aE0101"); ConversationMessage.create(message) .set("UserObj", user) .sendNowWith(bus); } } ... and pull it out on the client side ... bus.conversationWith(CommandMessage.create() .toSubject("UserManagement"), new MessageCallback() { public void callback(CommandMessage message) { User user = message.get(User.class, "UserObj"); System.out.println("::" + user.toString()); } }); This is one giant leap towards supporting things like WebBeans and JPA on the client side over ErraiBus. Thoughts? Mike.
