One embodiment of the present invention provides a system for profiling a virtual machine on an embedded device. During operation, the system receives an operation-request at a system-level profiler from a virtual machine on an embedded device. The system then records the operation-request in a system-level log. Next, the system sends the operation-request to a native layer on the embedded device. Then, the system receives an operation-response associated with the operation-request from the native layer. The system then records the operation-response in the system-level log. Next, the system sends the operation-response to the virtual machine, thereby facilitating logging of interactions between the virtual machine and the native layer. Note that logging interactions between the virtual machine and the native layer facilitates emulation of the platform independent virtual machine on a second device. Furthermore, note that logging interactions between the virtual machine and the native layer can facilitate emulation of the platform independent virtual machine executing a specific application on a second device.

Method and apparatus for profiling a virtual machine

One embodiment of the present invention provides a system for testing an application running on a virtual machine. Note that this involves the system profiling the application, and determining when the virtual machine is executing code in response to commands from the application and when a device hosting the virtual machine is executing code in response to commands from the virtual machine. During operation, the system executes the application. In response to executing the application, the system receives a code-level log associated with the application from a code-level profiler. Then, using a system-level profiler, the system creates a system-level log associated with the application. Next, the system combines the code-level log and the system-level log to produce a profile of the application. The system then analyzes the profile to determine if a problem exists in the application. Note that this can include identifying performance bottlenecks and 'hot spots,' which is code that is continually or frequently executed, and thus, facilitating removing application bugs and improving application efficiency.

A cloud connector key includes a network interface configured to connect to a network, a mass storage interface configured to connect to a network isolated device, and a computation module operatively connected to the network interface and the mass storage interface. The computational module is configured to connect to a cloud repository using the network interface by obtaining, from storage on the cloud connector key, a network address of the cloud repository, requesting connection to the cloud repository using the network address, and authenticating, using credentials in the storage on the cloud connector key, to an account in the cloud repository. The computational module is further configured to transfer a file between the account in the cloud repository and a network isolated device via the mass storage interface.

A method for testing functionality on a JAVA enabled device is provided. The method includes downloading a test to the JAVA enabled device from a management unit having access to the test. The management unit is connected with a partner device polling the management unit. A message is forwarded from the JAVA enabled device to the partner device through the management unit. The expected content of the message is forwarded from the JAVA enabled device to the partner device, through the management unit. The message is then compared to the expected content. A system and a graphical user interface are also included.

Distributed midlet testing

A method for communication includes coupling a client device to communicate with a host computer over a serial link. Responsively to a call from a client application running on the client device, the client device submits a request over the serial link to the host computer to open a proxy connection for communication between the client application and a server application. Responsively to the request, the host computer creates a socket for communication with the server application, so as to establish the proxy connection via the socket. The host computer and client device convey data between the server application and the client application over the serial link using the proxy connection.

An infrastructure is provided for creating applications for mobile information devices, using a tag-based markup language, MIDML. Applications are defined based on easily manipulated textual tags, without need for writing specific code. The tags are processed to ultimately generate source code files. Initially, the input is parsed. Next, a hierarchical object model of the application is populated with objects. Separate readers read and parse the different tags and accompanying elements. The readers are registered in a descriptor object factory, to be instantiated as required in processing extended MIDML files. The object model enables the capabilities of the system to be easily extended, simply by adding new tags, and readers to the existing factory set. The resulting object model is accessible to a generator that produces the actual output.

Language and object model for describing MIDlets

An infrastructure is provided for creating applications for mobile information devices, using a tag-based markup language. Developers can use the markup language to define applications and content based on easily manipulated textual tags, rather than having to write specific source code. A compiler, processes the tags in several phases. In one phase, a hierarchical object model of the application is populated with objects. Then, in another phase, a generator traverses the object model hierarchy in a top-down manner, producing source code files corresponding to objects in the object model. The code files may include various elements, for example screens, forms, and servlets. For each element required to be generated, an appropriately configured generator class is invoked. The output code can be Java source code.
