      Hi there, i am trying to set up a servlet(ReadAllAvailableProperties.java) to communicated with BACnet devices(SlaveDeviceTests.java). But all i get is the following error:

      HTTP Status 500 -

      type Exception report

      message

      description The server encountered an internal error () that prevented it from fulfilling this request.

      Anyone have any idea on this? I am @ a loss. :(

      EDIT: Manage to fix the problem by right click on the warning message on seroUtils.jar then click on Quick Fix -> Mark the associated raw classpath entry as publish/export dependency.

        You need to include seroUtils.jar in your class path.

        Best regards,

          Hi mlohbihler,

          I have already included it in the class path. Any advice? Previously I try to build it around a Java Swing and was successful but when i try it out in a Servlet, it return me the above mention error.

            Make sure you are using the most recent bacnet4J.jar too.

              Hi mlohbihler,

              Thank you for your reply. I actually imported the whole bacnet4j/src downloaded from your side instead of adding bacnet4j.jar as a classpath.
              Will that cause any error?

              Regards,
              WenJun

                If you're using the most recent source, then that code would be looking for org.apache.commons.lang3.ObjectUtils instead of the serotonin version. Make sure you have the latest, and then ensure that both seroUtils.jar and commons-lang3-3.0.jar are in your classpath.

                Best regards,
                Matthew
