Abstract: A method, apparatus, and system for providing a standard, generic contract between an application server and a message provider which allows the message provider to deliver messages to message endpoints (each of which is associated with a corresponding message application) residing in the application server is disclosed. By generic, it is meant that the contract is independent of the specific messaging style, messaging semantics and messaging infrastructure used to deliver messages. In this way, the contract also serves as the standard message provider pluggability contract that allows any message provider to be plugged into any application server via an associated resource adapter.

Abstract: Methods and apparatus for transporting data in a web server are disclosed. A HTTP request including HTTP request data is received by a data transport module from a client. The HTTP request data may be sent with a preempt indicator from the data transport module to a HTTP daemon. The preempt indicator indicates whether processing is preempted from the data transport module to the HTTP daemon. Similarly, when a HTTP response is returned from the HTTP daemon to the data transport module, HTTP response data may be sent with a preempt indicator from the HTTP daemon to the data transport module indicating whether processing is preempted from the HTTP daemon to the data transport module. In addition, an identifier identifying the HTTP response data may be returned to the data transport module which identifies the response and enables the data transport module to independently access the response for transmission to a client.

Abstract: A security architecture has been developed in which a single sign-on is provided. Session credentials are used to maintain continuity of a persistent session across multiple accesses to one or more information resources, and in some embodiments, across credential level changes. Session credentials are secured, e.g., as a cryptographically secured session token, such that they may be inspected by a wide variety of entities or applications to verify an authenticated trust level, yet may not be prepared or altered except by a trusted authentication service. Some embodiments of the present invention associate trust level requirements with information resources. Authentication schemes (e.g., those based on passwords, certificates, biometric techniques, smart cards, etc.) are associated with trust levels, and in some embodiments, with environmental parameters.

Various embodiments are disclosed.

Abstract: One embodiment of the present invention provides a system for compiling computer code to perform a subtraction operation between a first interval and a third interval to produce a resulting interval. The system operates by receiving source code within a compiler. The system next determines if a subtraction operation within the source code is a dependent subtraction operation, wherein the third interval is the sum of the first interval and a second interval. If so, the system produces executable code for the subtraction operation that computes a left endpoint for the resulting interval and a right endpoint for the resulting interval. If the left endpoint of the third interval is negative infinity, the left endpoint of the resulting interval is assigned to be negative infinity.

The present invention relates, in one aspect, to a method for analyzing a software component that can be visually moved within an application builder tool running on a computer. The method involves obtaining the software component to be analyzed and determining if the software component has an associated information class. When it is determined that the software component has an associated information class, the information class is queried about information stored within the information class, otherwise automatic analysis using design patterns is applied to analyze the class. In one embodiment, the information stored within the information class relates to methods, properties, and/or events.

Abstract: A method for providing a constant time reference to an operating system includes inputting a PCI clock and inputting a CPU clock. The method outputs a signal having a constant frequency which is a factor of the PCI clock and synchronized with the CPU clock. The method further involves using the output signal as the time reference for the operating system. The method provides a way by which the operating system can perform necessary tasks based on a constant time reference when the CPU clock is changing due to system power conservation requirements.

The digital process monitor includes: a ring oscillator that generates a series of clocked pulses, and a ripple counter that counts the clocked pulses. The count is measured for a prescribed period of time and the count corresponds to the performance of the integrated circuit.

Abstract: One embodiment of the present invention provides a system that uses a packet distribution table to distribute packets to server nodes in a cluster of nodes that operate in concert to provide at least one service. The system operates by receiving a packet at an interface node in the cluster of nodes. This packet includes a source address specifying a location of a client that the packet originated from, and a destination address specifying a service provided by the cluster of nodes (and possibly a protocol). The system uses the destination address to lookup a packet distribution table. The system then performs a function that maps the source address to an entry in the packet distribution table, and retrieves an identifier specifying a server node from the entry in the packet distribution table. Next, the system forwards the packet to the server node specified by the identifier so that the server node can perform a service for the client.

Abstract: A lossless compression mechanism for compressing and restoring data elements such as text, text formatting, video, audio, speech, and 2D and 3D graphical information. Each data element is compressed using a data structure having a bin number field and an offset field. The bin number field is associated to a bin having a range of values which includes the data element value. The offset field is computed from a minimum bin value, wherein the minimum bin value is associated to the bin and is stored in a bin lookup table. The bin number field is encoded using a unary code, and the offset is encoded using a binary code.

Abstract: Methods and computer systems for providing access to a protected resource are described. In an enterprise computer system, an authentication server provides a client requesting access to the protected resource a credential. In order to access the protected resource, the requesting client presents a protected resource access request in combination with the credential to a server coupled to the protected resource. The server, in turn, requests the authentication server to validate the credential. After the authentication server has validated the credential, the server grants the requesting client access to the protected resource.

Abstract: A system and method are provided for improved handling of data in a cache memory system (105) for caching data transferred between a processor (110) capable of executing a program and a main-memory (115). The cache memory system (105) has at least one cache (135) with several cache-lines (160) capable of caching data therein. In the method, a cache address space is provided for each cache (135) and special instructions are generated and inserted into the program to directly control caching of data in at least one ofthe cache-lines (160). Special instructions received in the cache memory system (105) are then executed to cache the data. The special instructions can be generated by a compiler during compiling of the program. Where the cache memory system (105) includes a set-associative-cache having a number of sets each with several cache-lines (160), the method can further include the step of determining which cache-line in a set to flush to main-memory (115) before caching new data to the set.

Abstract: A customized mailbox is provided to customers for placement outside their home. Simple electronics, such as a display, keypad, bar-code reader, and transmitter/receiver may be contained within the mailbox. When parcel delivery is attempted, the deliveryperson may facilitate the notification of the user by, for example, scanning a bar code on the parcel with the bar code reader. Parcel information is then wirelessly forwarded to a service provider. The service provider may forward parcel information a mobile device or other notification mechanism as specified in user preferences. Upon receipt of the parcel delivery information, the user may, through the mobile device or other notification mechanism, approve delivery of the parcel. The service provider may then forward this approval to the electronic mailbox, where an electronic lock may be opened and the deliveryperson may place the parcel in the electronic mailbox.

Abstract: A method, computer program, signal transmission and apparatus verify instructions in a module of a computer program during linking using pre-verification constraints with fully lazy loading. It is first determined whether a first module which is loaded has passed verification one-module-at-a-time before linking. If the first module has passed verification, a pre-verification constraint on a constrained module is read, if any. It is then determined if the constrained module is loaded, if any pre-verification constraint is read. If the constrained module is not already loaded, the pre-verification constraint is retained as a verification constraint.
