Abstract: The present invention enables designated data to be extracted from a structured document even when the structured document differs from others in terms of screen layout and document structure. A first structured document is read in and outputted to an output device; a first label to be extracted and first data to be extracted are acquired via an input device; an extraction pattern representing a relative relation in document structure between the first label to be extracted and the first data to be extracted is generated; and the extraction pattern is stored in a storage device.

Abstract: An aspect of the invention is a system for acquiring execution information of a process executed in a computer which receives an execution request of a process and a request to start acquiring execution information of the process from a client. An application execution part of a server part executes the process based on the execution request. An execution information acquirement control part of the server part stores execution information of the process executed by the application execution part in a storage device based on the request to start acquiring execution information. The stored execution information is displayed in response to a display request.

Abstract: Object information is read that denotes a load state of the object from storage and selects an object having a load that is lower than a predetermined value. Then, a reference to an object allocation control part is returned that allocates the selected object to a destination as a response through communicating means. In allocating an object, the object information is read from the storage to select an object having a load that is lower than a predetermined value. Then, a reference to a dispatcher is returned that executes the selected object to the destination as a response through the communicating means. In executing the object, the object information is read from the storage and executes the object if the object has a load that is lower than a predetermined threshold value.

Abstract: A method and its system for acquiring object reference information from a naming service. When executing an object, a retrieval request, which includes the object name of the object, is sent to a computer for providing the naming service. Next, the object is executed on the basis of object reference information acquired as the response to this retrieval request. Moreover, when executing the object, it is judged whether or not the object reference information on the object has been stored in a reference-information storage area into which the acquired object reference information is stored. Furthermore, if the object reference information has been stored therein, an execution request is sent which is implemented for executing the object on the basis of the stored object reference information.

Abstract: A distributed object system having a load balancing feature that can be expanded by adding a new computer to the cluster of server computers. Objects can be activated and deactivated and system service alteration is performed by renewing objects. By request from a client, the object invocation unit obtains object code and object data from the object access unit in response to remote object invocation, executes the requested method, and requests the object access unit to overwrite the object data. The object manager unit activates or deactivates an object.

Abstract: The invention offers a distributed object system that is provided with a load balancing feature and can easily be expanded by adding a new computer to the cluster of server-run computers. By the invention, objects are easily activated and deactivated and easy system service alteration is performed by renewing objects.
