An agent system processes information by agents. The agent system is connected to an agent system of different type through a network. A wrapper class memory stores component data of wrappers corresponding to each type of agent system. The wrapper specially processes information in a corresponding agent system. A wrapper generation section generates a wrapper corresponding to an agent system of a different type based on the component data of the different type in the wrapper class memory. The wrapper acts for the agent to use resources in the other agent system.
