    Hi All,

     

    I have created a custom jar file to read json object from json file and delete one of array and update the file. It is running fine when tested using dynamic java test execution step . 

     

    p.s - I have tried by exporting java code with referenced libraries and also adding explicilty json jars. but none of the ways are worked.

     

    DevTest Version - 10

     

    But when using this jar in vsm , getting parser exception error after deploying it on vse.

     

    stacktrace

     

    ============================================================================
    | Exception:

    Also , a weird behavior is observed. I am able to send the request to virtual service when it is deployed on vse. But when I ran it in ITR no request is captured at listen step and getting 404 not found exception.

     

     

    Thanks

    I would also apply the custom jar to the hotDeploy of where your VSE is you deployed the VSM to.

    Do you have all of your dependencies in the jar?

     

    Your application looks to be missing a class that is needed at runtime.

    Yes I have , even tried by explicitly placing all the required jars in hot deploy folder as well , but nothing works.

     

    Also , a weird behavior is observed. I am able to send the request to virtual service when it is deployed on vse. But when I ran it in ITR no request is captured at listen step and getting 404 not found exception.

    How are you submitting your request when you run in ITR?
