Abstract:

According to one embodiment, a wireless mobile messaging system architecture includes a virtual mobile messaging service (VMMS) client, a virtual mobile messaging system (VMMS) component, and a middleware server component. The VMMS client is adapted to run on a Java-enabled mobile device, the client including a user interface and a lightweight object request broker (ORB), wherein the user interface enables input of a client request to a messaging server. The VMMS component includes an enterprise Java beans (EJB) component and a mobile messaging server agent, wherein the EJB component is configured to operate on the Java application server to handle the client request to the messaging server via the mobile messaging server agent, and the mobile messaging server agent is configured to interface with the messaging server. Lastly, the middleware server component is adapted to support distributed object-oriented connectivity from the Java-enabled mobile device to the EJB component on the Java application server, the middleware component including a gateway server adapted to support transparent access from the Java-enabled mobile device to the EJB component on the Java application server, and wherein the lightweight ORB enables communication between the client on the Java-enabled mobile device and the middleware server component on the Java application server.

Abstract:

A method of implementing a client side remote method call from a Java-enabled mobile device includes executing an instruction at the mobile device to open a connection at a Host URL. The Host URL includes a server side object of the remote method call. An output stream is opened via the connection. Remote method call parameters are written to the server side remote method call object at the Host URL via the output stream. An input stream is opened via the connection for receiving return data from the Host URL. Lastly, the return data is queried for any occurrence of errors in the remote method call request in response the server side remote method call object and the remote method call parameters, wherein responsive to a detection of errors, remote method call error recovery process is executed for performing a restart of the remote method call in response to at least one recovery query prior to throwing a remote exception which terminates the remote method call.
