          Description

          Dear All,

          I am facing a problem with CEP, the engine should be running normal. I am
          trying to send events using REST Post and receive the output event in a
          file.

          http://194.28.122.118:8080/ProtonOnWebServer/rest/events

          {"Name": "TrafficReport", "volume": "1000"}

          But I am not receiving any change of output in the file, although the log
          file says that the input event is passed to proton.

          Any ideas would be really helpful since I am stuck on this problem for 3
          days now.

          Attached the catalina log and the definition file.

          Best,
          Ahmed Sadek

            Dear Ahmed,

            As you pointed out in previous communication, from the log you saw that the CEP can't open the output file:
            >>>
            Apr 3, 2015 3:58:30 PM com.ibm.hrl.proton.adapter.servers.AbstractServer startAdapters
            WARNING: initializeAdapters: failed to initialize adapter Output adapter for consumer: SysTemCrashConsumer, reason: No such file or directory
            Apr 3, 2015 3:58:30 PM com.ibm.hrl.proton.adapter.servers.AbstractServer startAdapters
            WARNING: initializeAdapters: failed to initialize adapter Output adapter for consumer: DoSAttackTRConsumer, reason: No such file or directory
            >>>

            This usually happen if the path specified as the Consumer's output file doesn't exist, or if you run on unix/linux and tomcat has no permission to write in this directory or to write to the specific file.

            I would also recommend to use an absolute path and not relative path for the output file, since in different operating systems, the Tomcat "current" directory may be different.

            So here are my recommendations:
            1. Stop tomcat
            2. Delete catalina.out
            3. Activate tomcat
            4. In the CEP web UI, change the path of the Consumers to an absolute path, save the project, export it to the repository
            5. Make sure the path you specified for the Consumers exists, and that tomcat has permission to write to the directory, and if the files exist, to this files.
            6. Change the status of the CEP engine to Stop
            7. Change the status of the CEP engine to Start
            8. Send an input event

            Make sure you don't see the warning listed above in the catalina.out
            Best regards,
            Tali
