摘要： A method, apparatus, and program code visually constructs object-oriented application software to be installed on a distributed object system. The method of the invention includes the following steps. Initially, the method provides a catalog facility which contains components having references to pre-existing objects within a distributed object system. A component is selected from the catalog facility for inclusion in the application software. A part corresponding to the object referenced by the selected component is derived from the selected component. The part is then made available to an application construction environment. In this environment, the part can be linked to at least one other part that also references a pre-existing object in the distributed object system. Graphical facilities are provided within the application construction environment for selecting and defining links among parts. Links define relationships between parts and thereby provide computer code for the application software under construction. When the part is linked to another part in the application construction environment, computer code is generated that will be effective to implement the relationship between the parts when the application program is run.

摘要： A method, apparatus, and computer program product for selecting and reviewing a distributed object installed on a distributed object system. A method of the invention includes generating a library of components corresponding to distributed objects on the distributed object system, which includes one component corresponding to the distributed object. Each of the components of the library includes information describing the distributed object to which the particular component corresponds. The contents of the library are displayed using a catalog interface device. The library is browsed using the catalog interface device to identify the component corresponding to the distributed object which is then selected. At least a portion of the information describing the distributed object is displayed.

摘要： A distributed object application builder apparatus filters an object definition to determine the information needed (plugs) and provided (sockets) by an object. Each part (a run-time instance of an object) in the builder has plugs and sockets that are interconnected to other parts to define a distributed object application. At run time, actual instances of objects are substituted for the parts. A method of determining the plugs of an identified part begins by retrieving the interface (object definition) that corresponds to the part. Once retrieved, the plugs of the part are identified by determining the object-valued attributes of the retrieved interface, determining the operations from the retrieved interface that require one object-valued argument, and retrieving the factory argument list from the factory method for the object. These attributes and arguments constitute the plugs of the part. Sockets of a part are determined similarly. The plugs of a part are determined based upon their matching with a previously chosen socket. Similarly, if a plug is chosen first from a part, this chosen plug is matched with a socket of another part. A distributed object application program is constructed by choosing a first part, filtering its interface to determine its plugs and sockets, and then choosing and filtering the interface of a second part. Once plugs and sockets are determined, they are connected to at least partially define a distributed object application program. The filtering takes place within a visual application builder using a graphical user interface to select and connect parts.

摘要： A distributed object application builder apparatus filters an object definition to determine both information needed (plugs) and provided (sockets) by an object. Each part (a run-time instance of an object) in the builder has plugs and sockets interconnected to other parts to define a distributed object application program. At run time, actual instances of objects are substituted for the parts. A method of determining the plugs of an identified part retrieves the interface (object definition) corresponding to the part.

A distributed object application program is constructed by choosing a first part, filtering its interface to determine its plugs and sockets, and then choosing and filtering the interface of a second part. Once plugs and sockets have been determined, they are connected to at least partially define a distributed object application program. The filtering takes place within a visual application builder using a graphical user interface to select and connect parts.

摘要： A client enabled to load and run Java applets in a distributed object computing system retrieves needed Java classes in a location-independent manner from various class servers in the system. Initially, the client queries a naming service of the distributed object computing system to determine the class server that contains the base class needed. A connection through an object request broker is made from the client to the class server. The client then requests the code for the base class from the class server by using the object request broker. The class server retrieves the code by either reading a file from its own local file set, or if the code is not local, queries the naming service for another class server that has access to the code for the base class. This process of finding a class server and determining if the code is local may be recursive as classes may be moved or renamed. The class server then returns this code to the client by way of the object request broker. The client determines whether the returned code contains any unresolved classes, i.e., classes that are used but not yet defined or loaded. The client requests code for any unresolved class in a manner as above for the base class. The client incorporates Java software to run the applets and ORB binding software to enable the software to make calls to the object request broker. A network class loader enables the client to load and resolve classes over a distributed object system.
摘要翻译：能够在分布式对象计算系统中加载和运行Java小程序的客户端以不依赖于位置的方式从系统中的各种类服务器检索所需的Java类。最初，客户端查询分布式对象计算系统的命名服务，以确定包含所需基类的类服务器。通过对象请求代理的连接是从客户端到类服务器。然后，客户端通过使用对象请求代理从类服务器请求基类的代码。类服务器通过从其本地文件集中读取文件或者如果代码不是本地的来检索代码，则查询可以访问基类代码的另一个类服务器的命名服务。查找类服务器并确定代码是否为本地的过程可能是递归的，因为类可能被移动或重命名。然后类服务器通过对象请求代理程序将此代码返回给客户机。客户端确定返回的代码是否包含任何未解析的类，即使用但尚未定义或加载的类。客户端以上述方式为基类请求任何未解析类的代码。客户端集成了Java软件来运行小程序和ORB绑定软件，以使软件能够对对象请求代理进行调用。网络类加载器使客户端能够通过分布式对象系统加载和解析类。

摘要： A technique for automating the assembly of networked, language independent objects into a network application for use in a distributed object computing system uses program templates and a symbol table. A schematic representation of the network application is formed within a visual application builder. The schematic representation defines connections among representations of previously defined distributed objects. These connections are formed among parts, plugs and sockets that are associated with representations of distributed objects termed components. The schematic representation of the network application is loaded into a symbol table and portions of the schematic representation are stored as a number of entries in the symbol table. These entries include identifier-value pairs; that is, identifiers are mapped to values. The program source files to be generated are determined and the program templates for use in generating the program source file are also determined. The program templates include identifiers that correspond to the entries in the symbol table. The program templates are combined with the symbol table to generate at least one program source file. Identifiers in the templates are replaced with the corresponding values from the symbol table. The program source file is suitable for being compiled and linked to form a portion of the network application.
