If the filter mode (com.sun.identity.agents.config.filter.mode property) is set to J2EE_POLICY or ALL (which is the default value set during the agent installation), the version 2.2–02 Oracle Application Server 10g agent returns an error in the amFilter log when a protected resource is accessed.
Workaround. See the additional task in the Post-Installation Steps Specific to Agent for Oracle Application Server 10g in Sun Java System Access Manager Policy Agent 2.2 Guide for Oracle Application Server 10g.
