A Common Object Request Broker Architecture (CORBA) software gateway includes at least one of a scheme of invoking remote CORBA operations via a Network Management System (NMS) rule language and a scheme of remote invocation of NMS rules via a CORBA interface.

A method and system for providing security protection to Common Object Request Broker Architecture (CORBA) objects located on a server. An EJB shadow object is created for the CORBA object. The EJB shadow object invokes an EJB security mechanism on behalf of the CORBA object, thus protecting the CORBA object from unauthorized object requesters. In a preferred embodiment, requesters are categorized and identified by their roles in the enterprise. Only those requesters having a proper role are authorized to access the requested object.

A method, apparatus, and computer implemented instructions for binding object references from a remote name space into a local name space using a Web application. Information is collected to generate a request for an object reference. Information, such as an application server to use as the source, a source name space path, an identification of destination server, and a destination name space path to which the object reference is to be bound, may be used. The request is sent using a communications protocol, such as hypertext transfer protocol to the application server to be used as the source for the object reference. An object reference is located using the name space. The object reference may be serialized into a format, such as a common object request broker architecture format and sent to the destination. The destination will unserialize the object reference and perform binding using the destination name space path.

The method meets the requirement of practicability.

Communications using the common object request broker architecture (CORBA) is disclosed. The communications are between a first computing device and a second computing device separated by a NAT device. The first computing device issues a request conforming to the CORBA protocol to obtain an IOR for an object from the second computing device. A first request interceptor on the first device adds a public IP address of the second computing device as user-defined data in the request. A second request interceptor on the second computing device extracts the IP address from the request and stores it. The second computing device builds the IOR for the object including embedding the public IP address of the second computing device in the IOR. The second computing device sends the IOR to the first computing device. The first computing device then establishes a successful connection to the public IP address received in the IOR.

In a distributed computing environment utilizing Common Object Request Broker Architecture (CORBA), a software status display tool that provides a graphical representation of the current operational status of all of the data sources in a computer network. The display tool accesses the CORBA Name Server and obtains all available references for object implementations and their CORBA Interface Definition Language (IDL) interface. The references and interfaces map directly to all of the data suppliers and servers and their respective interfaces. The display tool then interfaces with each and every supplier and server as if it were a corresponding client or consumer and based upon the data it is able to obtain it makes a determination of the state of that particular supplier or server. The display tool then logs the results of its determinations and presents a fundamental color-coded system-wide display of its determinations on a video device.

A method and system for allowing a PERL application to communicate with distributed objects. One embodiment comprises a method in which first an adapter program receives a request from a PERL application. The PERL request specifies a distributed object with which the PERL application desires to communicate. The adapter program translates the request from the PERL application. For example, the adapter program translates PERL data structures into a format which is compliant with a communication program. Then, the adapter program calls the communication program to access the distributed object via Common Object Request Broker Architecture (CORBA). After the adapter program receives a response from the communication program, the adapter translates the response to a form suitable for the PERL application. For example, the adapter program may need to translate a data structure into a PERL compliant form. Then, the adapter program passes the response to the PERL application.

The invention discloses a non-CORBA (Common Object Request Broker Architecture) waveform component loading circuit, and aims to provide a loading circuit capable of improving SCA system loading speed,and reducing reconstruction time.
