Java Mobile Podcast 20: Mobile AJAX
Web services and mash-ups of web services really bring a whole new dimension to the web and mobile computing. Terrence Barr, Vincent Hardy, and Akhil Arora have create Mobile AJAX as a subproject of the meapplicationdeveloper project to make it very easy for the Java ME developer to harness the power of Ajax-style web services. Interesting applications can be built by combining (mashing-up) information from these multiple sources and remote web services, limited only by application developers' imaginations. Mobile Ajax highlights what is possible through a number of demos as well that utilize libraries that interact with web services.

j1-2k7-mtW04: Enterprise Data Mashup Service (EDMS)
The Enterprise Data Mashup Service Engine project aims at building a Open-Source JBI compliant Service Engine which features * Ability to create relational mapping for spreadsheets, flatfile, HTML table, xml sources (webrowset), XQuery Rowset, *Using Netbeans Database Explorer to browse source tables,
* Drag-n-Drop these tables into the Mashup Editor to define the join conditions,
* Ability to view the resultset using the Mashup editor
* View Cache Management,
* Transforming the response to various formats by composing the output with an XSLT Service Engine,
* etc.,
and thus provides the mashed up views of enterprise data from heterogenous sources. These pre-canned, materialized views served by the EDM SE can be used by clients to build highly responsive and interactive Ajax powered web2.0 style enterprise applications using existing client-side frameworks.
