    I imported the project as listed on the tutorial page. I am using JEE 5 but still getting this error.


    Check the error I am getting;

    SEVERE: Servlet /restdemo threw load() exception

    I could not replicate this issue with MyEclipse 9.

    Can you please answer some more questions for me ?

    1) Share your build id from Help > About MyEclipse Enterprise Workbench > Build Id. Paste the Build Id here.

    2) Did you import the example from this link ?

    3) To which app server are you deploying the project to?

    4) Here are the steps I followed :

    a) Downloaded the file from the tutorial page.
    b) File > Import > Existing Projects into Workspace > Select archive file. Upgrade the project when it prompts to be compatible for MyEclipse 9.
    c) Right click project > Run As > MyEclipse Server Configuration > MyEclipse Tomcat.
    d) Right click project > MyEclipse > Test with REST webservices explorer
    e) You can test it as explained in the Section 5 of the tutorial.

    Let me know how this works for you.
