I have taken earlier this tutorial on adobe's site for building an application for mobile devices. The tutorial provides a war file. After deploying the war file on my tomcat server, a few directories are built. Most importantly, WEB-INF folder. This folder contains some java files on one subdirectory and the corresponding java classes on another subdirectory. It also contains other files and directories.
I might have understood it wrong, but I think the entirety of the WEB-INF folder is what 'data service' means. I think I need some instruction on how to proceed for build a data service.
I now want to build another application. I built my MySQL tables and java classes to retrieve info from the tables and to build my desired objects. However, I now do not know how to build the 'data service'.
I am trying to do some research centered around 'build data service' key-phrase, but I can't seem to find anything pleasing.
My questions, though, are:
are there maybe better key words to base my research on?
when building data services, do I go coding and creating directories one by one, or is there maybe a better way to do that?
thank you in advance.
