Discover how AppDynamics steps in to upgrade your performance game and prevent your enterprise from these top 10 Java performance problems, brought to you in partnership with AppDynamics.

In the last post I showed you how simple it is to expose CRUD REST operations on your database with TopLink/EclipseLink.

The next logical step is to then consume those with Oracle MAF to build a mobile application.

This is quite simple with the REST data control. All you need to do is just map the right URLs and create the operation.

Here is a quick demo:

One trick I show in the demo is how to delay the call to a REST service until the user actually provides a value to a parameter. A common issue people have when they have the parameter form and the results on the same page. The solution is easy using the refresh condition of the executables of the page and using the "ne null" check on the parameter value.
