In accordance with an embodiment, described herein is a system and method for supporting namespaces in a multitenant application server environment. The application server environment can include a domain with a plurality of partitions. A global namespace or JNDI tree bound to domain-level resources can maintain a collection of partition root nodes, with each partition root node being the root node of a partition JNDI tree. Each node in a partition JNDI tree is made partition-aware by including properties specific to a particular partition. An initial context for a partition can be created for use in dispatching resource lookup requests to the partition, and can be reused by other applications in accessing resources in the partition.

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.

Methods, software, and apparatus for transparently pairing data with a command object, with respect to the application which wishes to present the data, are disclosed. In one aspect of the present invention, a computer-implemented framework for associating data with a command object includes a data handler mechanism arranged to interface with an application which wishes to use the data. The framework also includes a data retriever mechanism that is arranged to obtain the data, and is in communication with the data handler mechanism, as well as a mapping mechanism, which is also in communication with the data handler mechanism, and is arranged to obtain the command object. In one embodiment of the present invention, the data is a stream of bytes, and the data handler mechanism is used to bind the stream of bytes to the command object.

Method and apparatus for discovering and activating software components

A development suite for developing and testing internationalized software includes, in addition to an ASCII English locale, a multibyte English locale. The presence of a multibyte English locale permits early discovery and correction of errors by English speaking developers which would otherwise only be found during localization of the software for a country where a multibyte representation was required. A system and a computer program product also utilize a multibyte English locale.

Methods, software and data structures for installing a component in a container suitable for display on a display screen as part of a graphical user interface are disclosed. In one embodiment, a name and desired location for a component are provided. Both the desired component and a component object table that is to be associated with the component are then created. The component object table is arranged to identify both the location and identity of the component. The component object table is then referenced in a container lookup table arranged to associate the component object table with a container at the desired location. In a preferred embodiment, the container is a sliding panel associated with a window suitable for display on the monitor. The sliding panel is capable of supporting a plurality of handles that act as independent sub-containers. The component object table includes a location identifier that identifies an edge of the window that the sliding panel is associated with, and a handle index indicative of a particular handle within the sliding panel.

Hardware and software improvements in workstations which utilize virtual addressing in multi-user operating systems with write back caches, including operating systems which allow each user to have multiple active processes. In virtual addressing, multi-user workstations, system performance may be improved significantly by including a virtual address write back cache as one of the system elements. Data protection and the reassignment of virtual addresses are supported within such a system as well. Multiple active processes, each with its own virtual address space, and an operating system shared by those processes in a manner which is invisible to user programs. Cache 'Flush' logic is used to remove selected blocks from the virtual cache when virtual addresses are to be reassigned.

A system and method provide transparent access from any system entry service to multiple account management services, and particularly to multiple authentication services on a computer system, supporting unified login and logout. Transparency between system entry services and account management services, including authentication, password, account, and session services, is provided by an application programming interface and a configuration file. The configuration file stores associations between system entry services, and selected account management services, and allows an individual system entry service to be associated with multiple different ones of a given type of account management service, such as authentication services. The application programming interface determines dynamically in response to a request by a system entry service for an account management operation, such as authentication of a user, which account management service is associated with the system entry service by reading the configuration file and queuing pathnames stored therein of the account management services associated with the system entry service currently connecting user to the system. The application programming interface then invokes the queued pathnames for the desired operation. Multiple login is provided by encrypting authentication tokens used by the authentication services associated with a given system entry service with a primary authentication token of one of the authentication services, and subsequently decrypting the encrypted tokens as needed to authenticate the user. With unified login, the user need only provide the primary authentication token. Unified logout is provided by locating and destroying credentials of the user created by the multiple authentication services in response to a request of the valid user to logout.

Pluggable account management interface with unified login and logout and

In a computer system executing a dynamically configurable operating system, a symbol definition image file builder is provided for building a symbol definition image file real time for utilities and application programs. The symbol definition image file is built upon receipt of an open request for the file and a current system definition image file does not exist. The symbol definition image file is deleted upon receipt of a close request for the file and it is determined that the file is no longer referenced and non-current. The symbol definition image file comprises all current symbol definitions and strings of the operating system. The current symbol definitions and strings are gathered by the symbol definition builder from the symbol and string tables of the root executable segment and the relocatable segments of the operating system that are currently loaded in memory. Additionally, prior to building the symbol definition image file, the symbol definitions image file builder inhibits automatic unloading of the relocatable segments until all accesses to the symbol definition image file are completed, thereby protecting the symbol definitions and the strings that are included in the symbol definition image files from becoming stale.

Improvements in workstations which utilizes virtual addressing in multi-user operating systems with write back caches, including operating systems which allow each user to have multiple active processes directed to the support of alias addresses, i.e., two or more virtual addresses which map to the same physical address in real memory Specifically, alias addresses are created so that their low order address bits are identical, modulo the size of the cache (as a minimum) for user programs which use alias addresses generated by the kernel, or wholely within the kernel. For alias addresses in the operating system, rather than user programs, which cannot be made to match in their low order address bits, their pages are assigned as 'Don't Cache' pages in the memory management unit (MMU) employed by workstations which utilize virtual addressing.
