The agent application (agentapp.war) is bundled with the websphere_v61_agent_3.zip distribution file and is available as follows after you unzip the file:
PolicyAgent-base/etc/agentapp.war
Deploy agentapp.war on the WebSphere Application Server 6.1/7.0 instance using the WebSphere Application Server 6.1/7.0 administration console or deployment command.
Important: You must use the same deployment URI that you specified for the “Agent URL” prompt during the agent installation. For example, if you accepted the default value (/agentapp) as the deployment URI for the agent application, use this same URI to deploy agentapp.war.
