Abstract

System and method for creating a wireless application from a web service definition language employs an algorithm that analyzes each message of the web service definition an maps the message to a wireless application message and a wireless application data structure. The message maps are used by a proxy at an edge of a wireless network to convert web service messages to wireless messages, and vice versa.

linking each one of the plurality of component mapping objects to the respective one of the plurality of message objects and to the respective one of the plurality of web service messages; and

generating a data structure representing the wireless application, the wireless application including the plurality of component mapping objects;

wherein the component mapping object maps message parts of each one of the plurality of web service messages to respective messages arts of each respective one of the plurality of wireless application messages.

2. The method as claimed in claim 1 wherein creating each component mapping object comprises creating a message field object and a field mapping object for each message part of each web service message, and linking each component mapping object comprises linking each field mapping object to the respective message field object and the respective web service message part.

3. The method as claimed in claim 2 further comprising:

selecting a message part;

determining whether the message part is an element declaration;

determining the element type if the message part is an element declaration; and

determining whether the message part is a simple data type, an enumeration or a complex type.

4. The method as claimed in claim 3 wherein upon determining that the message part is a simple data type, the method further comprises determining whether the simple data type is an atomic type, a list or a union.

5. The method as claimed in claim 4 wherein upon determining that the simple data type is an atomic type, the method comprises determining a corresponding data type using a translation table and updating the message field object based on the data type.

6. The method as claimed in claim 4 wherein upon determining that the simple data type is an enumeration, the method further comprises:

creating an enumeration object;

creating an enumeration mapping object;

linking the enumeration mapping object to the enumeration object and to a simple data type definition; and

for each enumeration value, creating an enumeration literal object and mapping it.

7. The method as claimed in claim 3 wherein upon determining that the message part is a complex type, the method further comprises:

creating a data object;

creating a component mapping object;

linking the component mapping object to the data object and to a complex type definition; and

determining whether the complex type has a base type.

8. The method as claimed in claim 7 wherein upon determining that the complex type has a base type, the method further comprises:

creating a data object;

creating a component mapping object;

linking the component mapping object to the data object and to a complex type definition;

setting the data object as a prototype for a current complex type; and

determining a category of the complex type.

9. The method as claimed in claim 8 further comprising:

determining whether the category is one of an empty, simple, mixed or element only;

if the category is one of the empty, simple or element only, determining whether there are any fields in the data object; and

if there are no fields in the data object, discarding the data object and the component mapping object.

10. The method as claimed in claim 9 wherein if upon determining that the category is mixed, the method comprises discarding the data object and the component mapping object.

11. The method as claimed in claim 9 wherein if upon determining that the category is not one of the empty, simple, mixed or element only, the method further comprises:

selecting an attribute of the complex type; and

determining whether the attribute is one of a fixed constraint and a prohibited use.

12. The method as claimed in claim 11 wherein upon determining that the attribute is not a fixed constraint or a prohibited use, the method further comprises:

creating a data field object;

creating a field mapping object;

linking the field mapping object to the data field object and to an attribute declaration; and

determining whether the attribute declaration is an enumeration or a simple data type.

13. The method as claimed in claim 9 wherein upon determining that the complex type has an “

Any”

attribute the method further comprises;

creating a data field object;

creating a field mapping object;

linking the field mapping object to the data field object and to the “

Any”

attribute;

setting the data field type to “

string”

;

determining whether there are any fields in the data object; and

discarding the data object and the component mapping object if the data object contains no fields.

14. The method as claimed in claim 9 wherein upon determining that the category type is simple, the method further comprises:

creating a data field object;

creating a field mapping object;

determining a content type of the simple category; and

determining whether the content is an enumeration or a simple data type.

15. The method as claimed in claim 9 wherein upon determining that the category type is element only, the method further comprises determining whether a particle of the category is an element declaration, and “

Any”

type or a model group.

16. The method as claimed in claim 15 wherein upon determining that the particle is an element declaration of “

Any”

type, the method further comprises;

creating a data field object;

creating a field mapping object;

Any”

type;

setting the date field type to “

string”

;

determining a maximum occurrences value of the particle; and

if the maximum occurrences value is greater than one, setting a field array property to “

true”

.

17. The method as claimed in claim 16 wherein if upon determining that the particle is a model group, the method further comprises:

for each particle in the model group;

creating a data field object;

creating a field mapping object;
