1. The log file on the Hawk HTTP Adapter system contains the error below. The location of this file is determined by the traceDir paramter in &lttomcatdir>/webapps//hawkhttp/WEB-INF/web.xml

javax.servlet.ServletException: javax.servlet.jsp.JspException: Server returned HTTP response code: 500 for URL: http://localhost:8080/hawkhttp/MicroAgents?Style=Nnames.xsl&Agent=sf11s01xxp01&Micro=FileSystem%3A0&Domain=ESBAdmin_CORP_PRD001_PRI

2. The &ltHawkdir>/logs/Hawk.log on the remote system will show:

Resolution:
--------------
   - If you see the "Unsecured request..." error message you need to do the following
     on the host that runs the HTTP adapter:
         * Uncomment the element containing
             &ltparam-name&gtSecurityPolicy</param-name> in hawkhttp/WEB-INF/web.xml.
            Thus, the HTTP adapter will use the security policy to communicate with the agent.
         * Restart the Tomcat server

   - If you see the "Permission denied" error, you need to examine the following
         * Is the user defined on the remote system? The request that goes
           to the remote system has the username of the webserver that hosts
           the Hawk HTTP adapter, i.e. the JRun process.
         * Make sure the OS user explained above has permissions
           to access these microagents in Trusted.txt. So if your OS username
           is myusername, edit Trusted.txt and add that user. Start by allowing everything
           by adding a line that contains myusername and nothing else. If this works
           you can proceed to restrict access per the policy you want to implement.
