Embodiments of the present invention provide a method, system and computer program product for melding mediation and adaptation modules of a service component architecture (SCA) system. A method for melding mediation and adaptation modules of an SCA system can include selecting each of a mediation module and an adaptation module in an integrated development tool executing in memory by a processor of a computer and loading respectively different descriptor files for each of the mediation module and the adaptation module. The method further can include combining descriptors from the different descriptor files into a single descriptor file for a melded module. Finally, the method can include modifying names and wiring descriptors in the single descriptor file for the melded module to account for a combination of the mediation component and the adaptation component in the melded component.

An apparatus and method for deploying web services in a web services infrastructure are provided. With the apparatus and method, a deployment descriptor for a web service is retrieved from a configuration file. A location type in the deployment descriptor is provided for identifying whether the web service is implemented using a web services description language (WSDL) document only, a JavaBean only, or both a WSDL document and a JavaBean. Based on the location type, and associated attributes of the location type, processes are performed for generating an internal definition of the web service to thereby deploy the web service in the web services infrastructure.

Flexible web service deployment

Mapping a source identifier in a source identifier space to a target identifier in a target identifier space using a hash-based computation that is stable over time with respect to a change in the number of target identifiers. A data item identifiable by a source identifier is associated with some type of computational resource that is represented by a target object identifiable by one or more target identifiers. The set of target objects is dynamically variable. After hashing the source identifier to produce an index position of an entry in a table, a target identifier is retrieved from the table entry. Each entry in the table is related to a single target identifier based on a nearness computation that depends upon the table index position of the table entry and a target identifier for the related target.

Stable hash-based mapping computation for a dynamically varying target set

A system and method are disclosed, according to which, the responsiveness of client/server-based distributed web applications operating in an object-oriented environment may be improved by detecting and handling affinity breaks between a client and server. Affinity exists when a client's requests are all routed to the same server. This is often the case, for example, during secure online transactions. A problem occurs when the preferred server becomes temporarily unavailable, and the client's requests are directed to a different server. When the original server is restored, it must detect the fact that its affinity with the client was disrupted, and any client-specific data in its cache may be invalid. In an exemplary embodiment of the system and method disclosed herein, an 'affinity command' is exchanged between the client and the server during each client request. The affinity command contains a user ID associated with the client and a 'generation ID', which is unique for each request. When a request is received from a client, the server examines the generation ID in the accompanying affinity command and compares it to its internally recorded value. If they match, the server knows it has not missed any requests. In this case, the server updates the generation ID and sends the new value back to the client, along with the requested cache entry. If the generation ID received from the client fails to match the recorded value, an affinity break is detected, and the server updates its cache from the database.

Methods, systems, and products are disclosed in which port type agnostic proxy support for web services intermediaries is typically provided by receiving in a web services intermediary a request for execution of a web services operation, wherein the request includes parametric information from which an endpoint for a target service that supports the operation can be identified; identifying, in dependence upon the parametric data, the endpoint for a target service that supports the operation; creating a target service request for execution of the operation on the target service; and issuing the target service request to the target service. Exemplary embodiments typically also include the return path of request-response processing: receiving in the intermediary a response from the target service; creating in the intermediary, in dependence upon the response from the target service, a response from the intermediary; and returning the response from the intermediary to the requesting client.

A methodology for providing a single-sign-on mechanism within an ASP aggregator service is presented. An aggregator token is generated by an ASP aggregator service and sent to a client device after its user has been successfully authenticated during a single-sign-on operation that is provided by the ASP aggregator service. The aggregator token then accompanies any request from the client to aggregated applications within the ASP aggregator service's infrastructure. The aggregator token comprises an indication of an address or resource identifier within the ASP aggregator service to which a client/user can be redirected when the client/user needs to be authenticated by the ASP aggregator service. In other words, the address/identifier is associated with a logon resource; when a request from a client is sent to this address, the ASP aggregator service responds with an authentication challenge to force the user to complete a single-sign-on operation.

A method, apparatus, and computer instructions for conducting an inventory of a data processing system. When a basic input output system (BIOS) is launched during a boot process for the data processing system, the basic input output system creates a hardware report of the data processing system. This report is sent to a remote data processing system on the network.

Exemplary embodiments typically also include the return path of request-response processing; receiving in the intermediary a response from the target service; creating in the intermediary, in dependence upon the response from the target service, a response from the intermediary; and returning the response from the intermediary to the requesting client.

An apparatus and method for deploying web services in a web services infrastructure are provided. With the apparatus and method, a deployment descriptor for a web service is retrieved from a configuration file. A location type in the deployment descriptor is provided for identifying whether the web service is implemented using a web services description language (WSDL) document only, a JavaBean only, or both a WSDL document and a JavaBean. Based on the location type, and associated attributes of the location type, processes are performed for generating an internal definition of the web service to thereby deploy the web service in the web services infrastructure. The internal definition may be generated from the WSDL document directly, if the location type is WSDL only. If the location type is JavaBean only, the internal definition may be generated by first generating a WSDL document from the JavaBean and then generating the internal definition from the generated WSDL document. If the location type is both a WSDL document and JavaBean, then the internal definition is generated from the WSDL document with a Java binding being added to reference the JavaBean.

Methods, systems, and products are disclosed in which port type agnostic proxy support for web services intermediaries is provided generally by receiving in a web services intermediary a request for execution of a web services operation, wherein the request includes parametric information from which an endpoint for a target service that supports the operation can be identified; identifying, in dependence upon the parametric data, the endpoint for a target service that supports the operation; determining whether the request requires a synchronous response; creating a target service request for execution of the operation on the target service; issuing the target service request to the target service; and waiting for a response from the target service if the request requires a synchronous response.
