Different Strategies to Develop Distributed Objects Systems at University of La Laguna
The use of Java Remote Method Invocation and Java Servlets allow the development of distributed systems. The University of La Laguna is made up of sixty departments on three separate sites. There are some 30,000 people involved in its day-to-day organisation, including students, teaching staff and service and administrative personnel. The geographical distribution of the University is a problem as far as administrative matters are concerned. Our developments in Web technology are giving users access to different services from their place of work or study. While the use of the Java version of CORBA, Java Remote Method Invocation, permits high interactive distributed applications; the Java Servlets provides an easy way to create three tier client/server applications over the Internet. In this work, we present end-user Web applications implemented using both techniques. The evaluation can be extended to any other organisation.
