Challenges and Resolutions for J2ME I Java by Oracle (originally from Sun Microsystems) is the most consistent name in the field of Software Development, Web Application Development and now, Mobile App Development. We use Java in variety of devices and variety of applications knowingly or unknowingly. Over three and a half decade of its existence, it has provided us solid programming language, Java Development Kit (JDK), other software development tools, applets, Java scripts, Virtual Machines, CMS support and a lot more. However, the scenario for Information Technology has changed. Previously providing best solution for enterprise software, Java has now got challenges in mobile app world and cloud computing. The software and applications are not bound to one node or dedicated network now. With more and more apps being available on cloud of app stores, all the software are becoming cheaper, small sized and focused performances. Java has to stand the competition to other open source platform as well. Challenges for Java 2 Micro Edition Java Micro Edition is a type of Java platform designed for small scale devices like mobile phones, PDAs and other embedded system devices like remote controls, set top boxes and a lot other appliances. Unlike Enterprise edition, this platform best serve in favor of mobile devices which has totally different hardware and software than high-end computers. Even if you are an expert J2SE or J2EE developer, for mobile devices, you have to face following things and have to answer them without fail –
Limited hardware availability Unreliable and slow networks Security issues due to device exposure Delicate devices Integration with cloud Scalability with various operating systems
These are merely some of the challenges any developer has to face while dealing with J2ME. However, most of these problems are from early devices, as smartphones and PDAs are enabled with a lot more capabilities than classic mobile phones. Developing a Java App For every Java App you develop, challenges stated above and a lot other have to be answered. Also, innovation and user friendliness are invariably associated with Java apps. Simply applying fundamentals of J2SE / J2EE for J2ME can be really harmful. A developer has to understand nature of mobile devices and targeted use of app. During our Java Application Development process, we take care of all these following points and considering them deliver innovative solutions to our clients. Observe Nature of App: For every app, there can be a different strategy. Hence, it is utmost important to understand nature of application before we begin, whether app is for enterprise or for consumer. Also, check whether it is for one-to-one, one-tomany, many-to-many, company-to-company or single person use. Smartly Manage Limited Hardware: There always ways out with Java. Managing with limited hardware without losing performance is a challenge and we have to answer it. Use Lightweight Libraries designed for mobile platforms that are widely available from variety of vendors. Optimize packaging process and try using partitioned application for reducing application footprint. Minimize garbage collector, too by increasing reuse factors for design objects. Setting up mobile portal servers can answer the issues for resource-intensive complex applications. Answer Network Related Issues: Mobile network are less reliable and slow compared to broadband networks. However, there are smart ways out for this situation, too. Prepare your app which supports offline mode so that it serves the user even in case of loss of network for some time using on-device persistence storage (cache).

Use remote facades to improve network efficiency with optimum object model at the server side remaining constant. Place mobile portals described above locally. Having single high end portal in wide area network sometimes loses control over multiple operations of enormous users. Placing portals in local network can improve usability. Use data encryption and buffered I/O for security and consistent operations. Solve for Pervasive Environment: With mobile devices, there is always a threat of data exposure and device security. J2ME developer must answer this issue. Protect on-device data by providing strong data encryption. Add multiple security layers for access of data or network externally. Allow user to synchronize data with other device in order to answer extensive battery usage and drained battery situation. Optimize app for many devices. This is a key factor for both consumer and enterprise use. In order to serve the purpose effectively, app must be friendly with many of the available devices, if not all. No one has time to hook up the device with computer to access its data or to synchronize. You can have a centralized data synch provisioning. This option is well suitable for enterprise apps. However, J2EE provisioning server provides this luxury to consumer apps, too. These are merely few points of discussion from the large ocean of information Java has in it. However, for any Java app development, points described above are must to answer. J2ME has a lot more to show us with Java Apps and we are going to be pleasantly surprised for sure!
