Hi,

I ran a standalone program in Java and it ran perfectly fine and then I created a smart service from it it gives NullPointerException as follows :-

    I have created the plugin using Appian plugin creator and re checked the smart service skeleton and my Java code. I haven't found any issue.

    Is there any issue related to environment ? Or is this the issue with my plugin ? Please let me know.

    @Mayank: Its hard to read the logs in this format, if possible can you attach the log file? Looking to the logs it seems, that you are trying to access a web service? if that is the case, can you attach your code also if possible.
