Illustrative embodiments provide a computer implemented method, data processing system, and computer program product for recovering resource connections using persistent subscriptions. In one illustrative embodiment, the method comprises subscribing to an event of a predefined resource to create a persistent subscription, wherein upon receiving notification of the event indicating the predefined resource is unavailable, and responsive to receiving the notification, reconnecting to the predefined resource. The method further comprises creating a new listener for receiving event notifications from the predefined resource, obtaining subscription information related to the predefined resource from the persistent subscription, and re-subscribing to the event of the predefined resource.

Recovering resource connections

A computer implemented method, apparatus, data processing system, and computer usable program code are provided for obtaining data from an application. A class loader layer is instantiated for an application. The class loader layer is an interface between the application and a resource adaptor and the class loader layer has access to all classes for the application. The function is executed to generate a set of objects with a set of data types accessible by the resource adaptor responsive to receiving a request from the resource adaptor to invoke a function in the class loader layer. Finally, the set of objects are sent to the resource adaptor.

Preventing an incompatible class exception caused by incompatible class loaders

Automatically creating a current project in an application developer workspace is provided. In response to reading a project file for the current project, it is automatically determined whether the current project has one or more dependent projects based on data contained within the project file. In response to determining that the current project does have one or more dependent projects, a build file is automatically generated for each of the one or more dependent projects. The build file calls importing targets within each of the one or more dependent projects. Then, the current project and the one or more dependent projects are automatically imported into the application developer workspace to form a created current project. The created current project is created without launching an application developer application. In addition, the created current project is stored in a source code control repository.

Creating projects in a rational application developer workspace

An apparatus and method for creating instruction groups for explicitly parallel architectures is provided. The apparatus and method gather information about the underlying architecture for use in an instruction group creation phase. The information gathered includes the number of each type of execution unit available and the number of bundles that can be dispatched concurrently by the architecture. The instruction group creation of the present invention includes three phases: a first phase for performing initial grouping, a second phase for hosting instructions from further down in the program instruction order if the instruction is not able to be added during the initial grouping phase, and a third optional phase for counting the number of bundles formed to thereby inform a Just-In-Time compiler of the amount of space need to be allocated in a code buffer.

A method and an apparatus for converting configuration information input in a format for a first version of a management protocol into configuration information for a second version of the management protocol is provided. In particular, a method and apparatus for converting Simple Network Management Protocol version 1/2c (SNMPv1/v2c) style community-based access configuration information into user-based access information for configuring a SNMPv3 agent is provided. The method and apparatus make use of various graphical user interfaces to allow a user to enter configuration information in a format with which the user is familiar. The method and apparatus of the present invention then maps the configuration information into a format used by the device being configured.

The present invention allows a multimedia session to be transferred from one application server to another in the event that the original application server fails, and also allows a session to be cooperatively transferred from one application server to another, even though the original application server is still available for use. The new application server may be in the same multimedia computer (i.e. the same physical machine) as the original application server, or the new application server may be in a different computer. The session is transferred without losing existing resources, and callbacks that occur during the session takeover process are not lost. An application server which owns a multimedia session may enable that session for takeover, by using an Application Programming Interface (API). The API returns session takeover data which must be available to a new application server in the event of a takeover. The new application server uses the session takeover data to reconstruct information, including access information, regarding all resources necessary to keep the session executing.

System and method for transferring a session from one application server

A system, method and computer program are provided for a control server in a client/server environment wherein an API framework facilitates scalable, network transparent, integrated multimedia content loading and data streaming. Concurrent real time content loading and data streaming are possible and techniques are included for admitting new streams only when they can be serviced without negatively affecting current system performance.
