    摘要： A stub retrieval and loading subsystem is disclosed for use in connection with a remote method invocation system. The stub retrieval and loading subsystem controls the retrieval and loading of a stub for a remote method, into an execution environment, to facilitate invocation of the remote method by a program executing in the execution environment. The stub retrieval subsystem includes a stub retriever for initiating a retrieval of the stub and stub loader for, when the stub is received by the stub retriever, loading the stub into the execution environment, thereby to make the stub available for use in remote invocation of the remote method. In one embodiment, the stub retrieval and loading subsystem effects the retrieval and loading for a program operating in one address space provided by one computer, of stub class instances to effect the remote invocation of methods which are provided by objects operating in another address space, which may be provided by the same computer or a different computer.

    摘要： A network proxy is provided that facilitates the integration of orphan services into a network by enabling them to interact with a lookup service that contains an indication of the services that are available on the network. These orphan services typically reside on devices having too little memory to run the components necessary to be integrated into the network. Thus, the network proxy acts as a go between, by registering the orphan services with the lookup service so that clients may access them and by accessing services on behalf of the orphan services. As a result, the network proxy integrates orphan services into the network, when they otherwise would be incapable of doing so.

    摘要： A database system wherein one or more entry databases store a plurality of entries. Each entry is of a given type that defines the fields of the entry. Each of the fields contains or identifies an object with associated attributes or data. The type of each entry may further define behavior in the form of methods the entry is configured to implement. An entry type which is a subtype of another inherits all of the fields and behavior of its supertype, and contains additional fields and/or defines new/modified behavior. Entries may be expressed in a Java.TM. class of the Java.TM. programming language. The database system may further employ a search engine which allows queries to be made upon entries in the database. In one implementation, the queries include a read operation, a take operation, and a notify operation. Each query request includes a command indicating the type of operation, and a template which is an entry object having some or all of its fields set to specified values that must be matched exactly. Other fields of the template entry may be specified as wildcards, whose values do not matter. The search engine may further be configured to create an index for entries having characteristics which are commonly specified by queries. Thus, the search engine may detect a pattern of usage and create an index which points to entries having attributes which are commonly specified by received templates. In this manner, expedient entry searching may be accommodated.

    摘要： A method for using dependency-based grouping to establish class identity comprises categorizing a plurality of classes into a set of class groups based at least in part on one or more dependencies between the classes, and generating metadata to be use for loading the classes, where the metadata includes a mapping between the set of class groups and the plurality of classes. The metadata may also include respective signatures for class groups and/or the individual classes. The method may also include validating, using at least a portion of the metadata, the identity of a particular version of a class of the plurality of classes, prior to loading the version for execution.

    摘要： A system consistent with the present invention enables a program in a distributed system to determine whether downloaded code is trustworthy before using the downloaded code to communicate with other programs or services in the distributed system. A client that downloads proxy code from a service can verify that both the service and the downloaded code are trustworthy before using the code to communicate with the service. “Trustworthy” code is code the client knows will enforce the client's security constraints in communicating with the service, e.g., mutual authentication, confidentiality, and integrity.
