Licas is a software package written in the Java programming language that allows a user to build distributed service-based networks that can also self-organise/self-optimise.

Functionality is provided to allow for XML-RPC based message passing and dynamic linking between services. The architecture and adaptive capabilities add something new to what other similar systems provide and the framework is also suitable for a mobile environment.

Mobile Environment

The licas software package is compatible with the Java 2 Micro Edition (J2ME) platform. The server code can be compiled to run under the latest CDC platform from SUN. The server is also compiled under J2SE and can run on any PC or laptop. However, any version that is now released will be compatible with the mobile environment. This means that the current version and any future versions will be restricted by the functionality of that platform. The GUI is only J2SE compatible. See the version history or bug fixes pages for details about the current or future changes.

Web Services Invocation

The system uses a default XML-RPC message passing mechanism. To make a call on a service, a Java object is parsed in the order 'Object-XML-String', which is then sent to the server and parsed back from 'String-XML-Object', when the appropriate method on the appropriate service can be called. There is now also the possibility for making Web Service calls. The licas server itself is not a Web Service, but a service acting as a client on it can call any third-party Web Service. The calling mechanism is not based on static stub classes, but is built dynamically from parsed WSDL documents. It is slightly different depending on which platform you are running (J2SE or J2ME), but the documentation describes how this is done.

Problem Solving

The system now has a problem solving version as a new separate package, written on-top of the main licas system. It is innovative in the sense that you can integrate it with a network and organise the services on the network based on the results of the heuristic problem solving search. Default solution type is genetic algorithms, with the idea of matching services with similar information content.
