....built over the file access system. It uses agents to perform full text keyword searches on the web pages of users. The next section presents an overview of the Ajanta system architecture. Most of the implementation details are omitted here; these details can be found in our other publications[9] [10]. Section 3 presents Ajanta s programming model and APIs. In Sections 4, 5, and 6 we describe three agent based applications. Finally, in Section 7 we present the conclusions and the future directions of our work. 2 An Overview of the Ajanta System Ajanta provides facilities to build ....

....extended to customize it for specific services by creating appropriate resources (objects) and making them available to the visiting agents through its resourceRegistry. A visiting agent can request access to a resource through this registry. The resource then constructs a suitably restricted proxy[10], based on its security policy, and gives to the agent a reference to this proxy. The agent cannot access the resources directly, and the proxy object ensures that sensitive operations are protected. Ajanta ensures that the proxy class is loaded from a trusted codebase. 2 Ajanta uses the Uniform ....

....execute the methods at the target UCIs. Figure 8 shows that to publish the chapter contents to remote hosts, an agent is created and dispatched. Here, an agent server, in our context the UCI, provides a secure execution environment for the hosting agents by a proxy based access control mechanism [21]. Figure 9: User Interface for the Author Role Each agent carries with it credentials, which include the identity of the agent s owner. When an agent arrives at a host, the agent server checks its credentials and verifies the agent s identity. Upon success, the agent server creates an exclusive ....

....5. A location independent global naming and name resolution mechanism that facilitates communication between mobile objects. The next section presents an overview of the Ajanta system architecture. The details of its implementation are omitted, as they can be found in other publications [15, 26, 14]. Section 3 presents its agent programming primitives. Section 4 elaborates on the concept of building agent applications using itineraries and re usable patterns of migration. In Section 5, we describe two applications that we developed to test the capabilities of the Ajanta primitives. 2. ....
