Deploying and running Java applications on a single host is covered by standard approaches. However, when applications are dynamically deployed on distributed hosts, the situation is quite different. In this context, applications are likely to be composed of classes, located in remote repositories and possibly related to identical class names. Hence, the typical class loader approach is no longer feasible to resolve the right byte code. Moreover, the native Java Runtime Environment (JRE) has originally not been designed to host more than one application concurrently within a single Java Virtual Machine (JVM). Thus, there are also unresolved issues concerning hosting distributed applications. In this paper, we present a new approach for a customizable Java application middleware with respect to the topics of application deployment, composition and hosting. Finally, the application of the approach within a distributed middleware platform is presented, wherein applications are customizably deployed, dynamically composed and concurrently hosted.
