JMaki provides a number of Web can be embedded in the application's data on the components. For the majority of small parts used, to be bundled with the database back-end, for example, we have to consider the design of a show you need to stock information Table small parts. This paper will set out to create Web applications such steps, the application deployed in the GlassFish V2, which includes a jMaki packaging Yahoo Data Table small parts for JavaDB recover from the data.
