A web services message broker architecture. In one embodiment, a system may include a server system and a plurality of applications, each configured to implement one or more enterprise functions and to execute on the server system. The system may further include a web services message broker configured to execute on the server system and to present a central web services interface to the plurality of applications, through which a given one of the plurality of applications is configured to communicate with a web service. In one specific implementation of the system, the web services message broker may be further configured to receive an incoming web service request and to convey the incoming web service request to one of the plurality of applications.

Web services message broker architecture

A method and system for managing events associated with either the client or the server using a controller framework includes initiating a request at a client. The request triggers an event that is processed using a client controller on the client. The client controller registers the event on the client, forwards the event to a server controller on a server, polls the server controller on the server periodically for information related to the event and retrieves notifications in response to the request or upon a poll. The client controller communicates with the server controller using asynchronous communication. The response retrieved by the client controller is loaded onto the browser of the client dynamically and rendered at the client as and when notifications are received from the server.

A proxy server containing a cache for retrieving information from a server and transmitting this information to multiple concurrent clients. A thread is created for each client requesting the information from the server. As long as information is contained in the cache, all the threads assume the role of a consumer thread by retrieving this information from the cache and placing it in an output stream to be sent to the client associated with each consumer thread. When one of the threads reaches the end of the information contained in the cache, it assumes the role of a producer to send a request to the server to retrieve additional information. When the producer thread receives the information from the server, it places it in an input stream for the cache. The producer thread then reverts back to a consumer thread to retrieve this information for its associated client. All other consumer threads may also retrieve this data from the cache. In retrieving information from the server, there may be multiple producers and consumers, however it is preferable that only one thread will be a producer at any given time.

Bounding delays and reducing threading overheads in caching

A proxy server operative to accept plug-in filters to perform forward and reverse filtering between a client process and a server process. In accordance with one aspect of the invention, a method of filtering information includes the steps of receiving a request by the proxy server from a client. The proxy server identifies a Uniform Resource Locator (URL) of a server process in the request and compares that URL against filter rules previously defined to the system. In the event the URL satisfies one of the filter rules, a filter servlet associated with the satisfied filter rule is used to filter the requested information. A filter servlet is a set of instructions that, when executed, filters the information. The filtered request is then used to retrieve information from a server process. Similarly, the same filtering process may be performed on a response from the server process destined for a client process.
