1. A computer-implemented method for deploying contents of a Web services archive comprising: searching the Web services archive for a metadata descriptor file that describes a mapping between a Web service described in the Web services archive and a Web Services Definition Language (WSDL) file that includes mapping information that is stored in the Web services archive; reading the metadata descriptor to determine which Web service is described in the Web services archive; storing the metadata descriptor and the mapping information in a Web services registry; generating a set of objects to serialize and deserialize input parameters using a types descriptor that specifies a mapping between XML complex types and Java class files and the WSDL file of the Web services archive; retrieving the mapping information from the Web services registry; and storing the mapping information as web service data in a cache that is accessible within a message processing runtime framework by the Web service to process messages, the mapping information including a plurality of mapping descriptors that include a first mapping descriptor, the first mapping descriptor including a first value that corresponds to a first message and a first method descriptor that corresponds to a first method.
