1. A method of deriving web service interfaces from form and table metadata comprising:
- receiving from a service client at a discovery subsystem a first request for services that are available on an application server;
responding to the first request with a web service entry corresponding to a form registered in a database table as a service, wherein the form definesa user interface of an application,an external view of an entity,which fields are visible in the external view of the entity,whether the external view of the entity allows one of a read, a modify, an insert and a delete function to be operated on the entity, andwhether particular fields in the external view of the entity are one of read-only or editable;
receiving from the service client a second request for a description of the service;
retrieving form metadata regarding the form on the application server;
determining from the form metadata what fields from what tables are shown on the form;
retrieving table metadata regarding properties of the fields, wherein each of the fields shown on the form appears as a field in the XML type using a name and type of the field from the table metadata; and
using the form metadata and the table metadata to respond to the second request with a description of the service in the Web Services Definition Language (WSDL) format.

Abstract
A system and method of deriving web service interfaces from form and table metadata is disclosed. The method uses a discovery subsystem to discover services that are available on an application server, retrieves the metadata descriptions of the services on the application server and uses the services discovered and the metadata descriptions to create web services interfaces such that the service is available using web services description language.

9. A computer readable storage medium comprising computer executable code for deriving web service interfaces from form and table metadata, wherein the computer code further comprises code for:
-
receiving from a service client at a discovery subsystem a first request for services that are available on an application server; responding to the first request with a web service entry corresponding to a form registered in a database table as a service, wherein the form defines a user interface of an application, an external view of an entity, which fields are visible in the external view of the entity, whether the external of the entity allows one of a read, a modify, an insert and a delete function to be operated on the entity, and whether particular fields in the external view of the entity are one of read-only or editable; receiving from the service client a Web Service Description Language (WSDL) request for a description of the service; retrieving form metadata regarding the form on the application server; determining from the form metadata what fields from what tables are shown on the form; retrieving table metadata regarding properties of the fields; and using the form metadata and the table metadata to respond to the WSDL request with a description of the service in the WSDL format. - View Dependent Claims (10, 11)

12. A computer system comprising a processor for executing computer executable code, a memory for storing computer executable code and an input/output circuit, the computer executable code further comprising code for deriving web service interfaces from form and table metadata, wherein the computer code further comprises code for:
-
receiving from a service client at a discovery subsystem a first request for services that are available on an application server; responding to the first request with a web service entry corresponding to a form registered in a database table as a service, wherein the form defines a user interface of an application, an external view of an entity, which fields are visible in the external view of the entity, whether the external view of the entity allows one of a read, a modify, an insert and a delete function to be operated on the entity, and whether particular fields in the external view of the entity are one of read-only or editable; receiving from the service client a Web Service Description Language (WSDL) request for a description of the service; retrieving form metadata regarding the form on the application server; determining from the form metadata what fields from what tables are shown on the form; retrieving table metadata regarding properties of the fields; building an XML type comprising a name of the service and a field corresponding to each of the fields shown on the form using a name and type of the field from the table metadata; and responding to the WSDL request with a description of the service in the WSDL format comprising the XML type.
