Cloud computing has become very popular in recent years. Various SaaS, PaaS and IaaS systems for collaborative software development have been proposed. We also have proposed a PaaS system that delivers both a server-side development and server-side execution environment for character user interface applications that can be executed on the server machine and a server-side development and client-side execution environment for graphical user interface applications that can be executed on the client machine.
Our previous system allows user to develop and execute software on a web-browser. But our previous system assumes standard PC to execute graphical user interface applications. The graphical user interface applications that are developed in our previous system cannot be executed on mobile devices such as smart phone and tablet. Therefore this paper proposes an extension of web-based software development environment. By the extension, our system allows software developers to implement software for mobile devices.
