    摘要： A system and method for searching for documents within spaces in a distributed computing environment are provided. A client sends a lookup message to a space which stores documents. The lookup message may specify desired characteristics, such as a name or partial XML schema, of the stored documents. The documents may include XML service advertisements and XML device advertisements as well as general-purpose XML documents. A set of zero or more documents which match the lookup message are discovered. In one embodiment, the lookup message may include a desired name. If the lookup message includes both a desired name and a desired schema, the set of discovered documents may include both discovered documents having a name that matches the desired name and discovered documents having a schema that matches the desired schema. If the lookup message includes neither a desired name nor a desired schema, the set of discovered documents may include substantially all the documents stored in the space. After the matching documents are found, the space may send a lookup response message to the client. For each discovered document, the lookup response message may include a name and an advertisement. Each advertisement may include information which is usable by the client to obtain the respective discovered document or access the resource (e.g., a service) that the document advertises. The advertisements and messages may be expressed in a data representation language such as XML.

    摘要： A service discovery protocol may allow clients to discover services on a proximity basis. A service device that provides one or more computing services may support a proximity communication link. A client device may form a proximity communication link with the service device. The client device may directly request from the service device a document that describes an interface to access a service provided by the service device. The service device may provide the document directly to the client device over proximity communication link. The document may include a service advertisement for the service, and the service advertisement may include a schema specifying an interface to at least a portion the service. The client device may use the information from the document to access the service. The client device may support a transport connection in addition to the proximity communication link, and the client device may make the document available to other devices over the transport connection. Thus, the client device may provide a bridge from the transport connection to the proximity communication link so that other devices from a distributed computing environment may access the service.

    摘要： A virtual machine (e.g. the Java Virtual Machine (JVM)) may include extensions for compiling objects (e.g. Java Objects) into data representation language (e.g. XML) representations of the objects, and for decompiling representations of objects into objects. The virtual machine may supply an API to the compilation/decompilation extensions. The compiler/decompiler API may accept an object as input, and output a data representation language representation of the object and all its referenced objects (the object graph) in a data stream. In addition, the compiler/decompiler API may accept a data stream, which includes a representation of the object and all its referenced objects (the object graph), and output the object (and all the objects in its object graph). In one embodiment, an intermediary format may be used to represent a data representation language document and may be dynamically processed to generate a class instance from the data representation language document.

    摘要： Various embodiments of mechanisms for bridging data representation language messaging based distributed computing environments to foreign environments are described. A device proxy may implement a device protocol and a distributed computing environment protocol to bridge devices into the distributed computing environment. A client proxy is described that implements the distributed computing environment protocol on behalf of a foreign client such as a browser. A service proxy is described that implements the distributed computing environment protocol on behalf of a foreign service. A transport proxy is described that routes data representation language messages between two different message transports. A distributed computing environment client proxy may allow distributed computing environment clients to access Remote Method Invocation (RMI)-based environment services. An RMI-based environment client proxy may allow RMI-based environment clients to access distributed computing environment services.

    摘要： A virtual heap for a process executing within a virtual machine is described. In one embodiment, the virtual persistent heap may allow the running of an application on a physical heap that is smaller than may otherwise be required. As an example, the virtual persistent heap may be an order of magnitude larger than the physical, in-memory heap. This feature is important for small consumer and appliance devices, as these devices may have a limited amount of memory. In one embodiment, the virtual heap may be maintained on non-volatile memory storage external to the device running the virtual machine, and portions of the heap for the current execution state of the process may be cached in and out of a “physical” heap resident in local memory on the device. For example, the device may connect to a server on the Internet, and the server may provide non-volatile storage space for the virtual heap. In another embodiment, the external storage for the virtual persistent heap may reside on a non-volatile storage attached to the device, for example, a Flash card or hard disk drive. In one embodiment of the virtual heap, the entire heap for a process may be made persistent. The virtual persistent heap may enable the checkpointing of the state of the computation of a virtual machine, including processes executing within the virtual machine, to a persistent storage such as a disk or flash device for future resumption of the computation from the checkpoint. The Virtual Persistent Heap also may enable the migration of the virtual machine computation states, and thus the migration of executing processes, from one machine to another. The saved state of the virtual machine heap may also provide the ability to restart the virtual machine after a system crash or shutdown to the last saved persistent state, and to restart a process that was running within the virtual machine prior to the system crash or shutdown to a checkpointed state of the process stored in the virtual persistent heap. This persistent feature is important for small consumer and appliance devices, as these appliances may be shutdown and restarted often.

    摘要： A distributed computing environment may employ spaces to provide a rendezvous mechanism that brokers services or content to clients. Services may advertise themselves in a space. Clients may find the advertisements in a space and use the information from an advertisement to access a service using a messaging mechanism. A space discovery protocol may be provided to find a space. A client may instantiate a discovery service to locate spaces. A listener agent may be configured associated with one or more spaces to listen for discovery requests. The listener agent may listen on various network interfaces, and may receive requests from clients looking for a space(s). The listener agent then responds with the service advertisement(s) or URIs for the service advertisements of the requested space(s). In one embodiment, the listener agent may be separate from the space and its functionality orthogonal to the functionality of the space.

    摘要： A secure interface between clients and services in a distributed computing environment is described. Method gates may provide an interface to remotely invoke functions of a service. A method gate may be generated from an advertisement that may include definitions for one or more messages for remotely invoking functions of the service. A client may generate messages containing representations of method calls. The service may invoke functions that correspond to the set of messages. A method gate on the service may unmarshal the message and invoke the function. The client may receive the results of the function directly. Alternatively, the results may be stored, an advertisement to the results may be provided, and a gate may be generated to access the results. Message gates may perform the sending and receiving of the messages between the client and service. In one embodiment, functions of the service may be computer programming language (e.g. Java) methods. In one embodiment, a message including a representation of a method call may be generated when no actual method call was made. In one embodiment, a method call may be transformed into messages that may be sent to the service; the service may not know that the messages were generated from a method call. In one embodiment, a service may transform messages requesting functions into method calls; the client may not know that the service is invoking methods to perform the functions. A credential may be embedded in messages and used for message authentication on the service.

    摘要： A system and method for interaction and access to shared content among clients and services in a distributed computing environment. A client may access a space service. The space service may store one or more XML service advertisements and/or other XML content in a space, and each of the service advertisements may include information which is usable to access and execute a corresponding service. The space service may include an XML schema which specifies one or more messages usable to invoke functions of the space service. For example, the schema may specify methods for reading advertisements from the space and publishing advertisements in the space. In accessing the space service, the client may send information such as an XML message (as specified in the schema) to the space service at an Internet address. In accessing the space service, the client may search the one or more service advertisements stored in the space. The client may select one of the service advertisements from the space. The desired service may be executed on behalf of the client. Upon execution, the service may generate a set of results. In one embodiment, these results may be published in a new space which may be accessed by the client for whose benefit the service was executed.
