The agent application (agentapp.war) is a housekeeping application used by the agent for notifications and other functions such as cross domain single sign-on (CDSSO) support.
The agent application (agentapp.war) is bundled with the jboss_v42_agent_3.zip distribution file and is available as follows after you unzip the file:
Deploy agentapp.war on the JBoss Application Server instance using the JBoss 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.
