The middleware offers the powerful abstraction of a remote method invocation. Yet there are the following problems. 1.Middleware-specific code can not be isolated in a single module. Thus, it is difficult to adapt the program to another middleware or a new distribution structure. 2.Middleware has certain restrictions; it is for example not possible to directly instantiate an object in a remote address space. In order to overcome the first problem, the approach presented in this thesis is based on the generation of a distributed application on the basis of a non-distributed source code. The specification of the distribution information is based on the attachment of elements of the application's class diagram to so-called partitions (the application is split into multiple partitions). In case that restrictions of the middleware are violated – this is automatically checked by an analysis tool – predefined operations can be used to transform the application in a suitable way. The implementation of the approach presented here employs a graph as its internal data structure. The graph rewriting system PROGRES is used to specify the structure of this graph and suitable transformations.Aachen : Publikationsserver der RWTH Aachen University IV, 191 S. : graph. Darst.
