Protokollunterstützung für SOAP Web Services auf mobilen Geräten
Abstract
Das HTTP Protokoll hat sich in weiten Bereichen als Quasi-Standard zur Übertragung von SOAP Nachrichten durchgesetzt. Geht es jedoch darum, Web Services auf mobilen Geräten anzubieten oder Web Services von mobilen Geräten aus zu konsumieren, so wirkt sich die Einheit von HTTP-Request und HTTP-Response häufig nachteilig aus. Dieser Beitrag diskutiert, wie sich alternativ asynchrone Protokolle für die Übertragung von SOAP Nachrichten einsetzen lassen. Weiterhin wird eine prototypische Realisierung einer Architektur vorgestellt, die ein SOAP-over-E-Mail-Binding realisiert und dabei typische Randbedingungen auf mobilen Kleinstgeräten berücksichtigt.
... • Reduction of the amount of data transmitted during a Web service call, while leaving the rest of the Web service stack untouched ( [2], [8], [7], [14], [16]). • Introduction of a message queuing infrastructure that queues SOAP messages for retrieval when the device connection is ready for it [3]. • Ignorance of transmission failures, probably for noncritical service calls ( [9], [13]). ...

Mobile Web services lie on the intersection of two big IT trends, namely Service-oriented Architectures (SOA) and mobile applications. So, their usage is likely to expand dramatically in the next years. However, the heavyweight nature of service-orientation in terms of the messaging-overhead that is necessary in order to achieve interoperability and loose-coupling comes in contrast with the lightweight nature of mobile devices and with the need to transmit wirelessly as few data as possible. This study categorizes the mechanisms that have been designed in order to bridge this gap, provides comparisons, discusses the results of related experiments, and introduces the future scenario in which the insights of the study can be exploited.
