System and method for simple object access protocol access to interface definition language based services

A method of mapping an object request broker interface definition language (IDL) based communication to a simple object access protocol (SOAP) based communication, the method comprising:

• receiving an IDL schema at a proxy service server from a business integration services system;
• processing the IDL schema to identify an IDL union element having a boolean discriminator type, the IDL union element including a portion that indicates an optional element;
• mapping the optional element of the IDL union element to an XML schema sequence element with a minimum occurs value of zero that differs from a maximum occurs value;
• generating an XML schema to include the XML schema sequence element;
• and
• sending the XML schema from the proxy service server to a business application services system.

A method of mapping an object request broker interface definition language (IDL) based communication to a simple object access protocol (SOAP) based communication, the method comprising:

• receiving an IDL schema at a proxy service server from a business integration services system;
• processing the IDL schema to identify an IDL interface type that includes only one or more IDL constant strings;
• mapping the IDL interface type to an XML schema type by creating one or more XML schema enumerations, wherein each of the one or more XML schema enumerations is identified as an enumeration and is associated with a respective IDL constant string that is identified as a constant, and each of the one or more XML schema enumerations having a value set to a string value of the respective IDL constant string;
• generating an IXML schema to include the one or more XMIL schema enumerations;
• and
• sending the XML schema from the proxy service server to a business application services system.

A method of mapping an object request broker interface definition language (IDL) based communication to a simple object access protocol (SOAP) based communication, the method comprising:

• receiving an IDL schema at a proxy service server from a business integration services system;
• processing the IDL schema to identify an IDL union element having a non-boolean discriminator type and to identify an IDL union element having a boolean discriminator type, the IDL union element including one or more optional elements;
• mapping the IDL union element to an XML schema sequence that includes one or more XML schema sequence elements, each XML schema sequence element corresponding to a respective optional element, wherein the XML schema sequence elements corresponding to the respective optional element of the IDL union element with the boolean discriminator type has a minimum occurs value of zero that differs from a maximum occurs value;
• generating an XML schema to include the XML schema sequence;
• and
• sending the XML schema from the proxy service server to a business application services system.

A proxy server system to map interface definition language (IDL) based communication to a simple object access protocol (SOAP) based communication, the system comprising:

• a data input to receive IDL data items to be mapped to an XML data item
• a data output to provide a SOAP output including the XML data item;
• a processor responsive to the data input and coupled to the data output, the processor including computer instructions to:
• process an IDL schema to identify IDL identifiers having an added prefix, the added prefix added to avoid a naming conflict with respect to a type within the IDL schema, to identify a first IDL union element having a boolean discriminator type and including a portion that indicates a first optional element, and to identify an IDL interface type that includes a constant string;
• map each of the IDL identifiers having the added prefixes by removing the added prefixes to produce prefix-less identifiers;
• map the first optional element of the IDL union element to a first XMIL schema type including an optional XML schema sequence element having a minimum occurs value of zero that differs from a maximum occurs value;
• map the IDL interface type to a second XML schema type by creating an XML schema enumeration having a value set to a string value of the constant string;
• and
• generate an XML schema including the prefix-less identifiers, the first XML schema type, and the second XML schema type including the XML schema enumeration.

A computer enterprise system comprising:

• a business application service (BAS) system including a simple object access protocol (SOAP) interface;
• a business integration services (BIS) system including a common object request broker architecture (CORBA) interface definition language (IDL) interface;
• and
• an integration services system coupled to the BAS system and coupled to the BIS system, the integration services system including a proxy server configured to:
• identify an IDL union element having a boolean discriminator type, the IDL union element including a portion that indicates an optional element;
• map the optional element of the IDL union element to an XML schema sequence element with a minimum occurs value of zero that differs from a maximum occurs value;
• and
• generate an XML schema to include the XML schema sequence element.
