Designing single-page applications
More and more developers are adopting the idea of building single-page applications to avoid page refresh. Because every click or interaction refreshes the page, it is ineffective approach for users to move through an app. When you plan your mobile application for a single-page, you plan a fluid and interactive application.
But the big question is how you validate user inputs with single-page apps. This issue can be solved if applications validate most content on the client and the entire procedure will not obstruct interactivity and responsiveness of user experience.
Single-page applications can also use all mobile device features such as camera, accelerometer and GPS to deliver a great experience to users. These apps can also use powerful visual components to present information in the user-selected format.
Separate User Interface and Server
The architectures of Java based applications do not allow user interface developers to collaborate effectively with server-side developers and thus these applications look terrible. If developers succeed to create a clear separation between of both, they will also succeed to create richer applications. A clear separation made using REST interface and/or JSON payloads let both developers focus on their areas of expertise.
Real-time update to content
If you are building web apps, seeing real-time information can be a big problem. But this issue can too be solved through JVM (Java Virtual Machine). JVM based application use real-time push that can also update data in real-time. The best example of app includes Google Docs that keeps saving documents automatically. This feature is called instant collaboration.
This method lets you build an app with rich user experience that instantly updates content.
Build a stateless architecture
CORBA allows developers to take on the idea of creating clusters of servers that replicate state across them. The approach is quite suitable when it comes to distributed architectures. JEE Entity Bean fits to fulfill a similar role. Developers keep avoiding such architecture because of performance and complexity reasons.
Most mobile developers fail to address the above mentioned four issues, but expert mobile app developers are able to make most out of them.
