HeadlessException when deploying war file

I have created a war file using Ready!API, and then I want to deploy it to Jetty. This works fine on a Windows machine, but when I try to do it in Jenkins (running Linux) I get:

I can see that the exception comes when doing some licensing checking, so I have the following questions:

 

1. Should a war file created with Ready!API be possible to run in Jetty without having a Pro license?

- If yes, then why does it fail on a headless server?

- If no, then why doesn't it fail on a Windows machine?

 

2. Jenkins has already specified -Djava.awt.headless=true, what else can be done to avoid the exception?

      Hi Rao, you're right that a license is required to run the Ready!API GUI application.

      However, my question is about deploying/running a war file created from SoapUI/Ready!API - as you can see from my post, this works well when running on Windows, but fails when running on a headless Linux server. So I'm hoping to get some insight from SmartBear - is it a bug that it's working on Windows or is it a bug that it's not working headless?

        A bit more trial and error indicates that:

         

        • A war file generated by Ready!API requires a license to be used
          • This means that it's a bug when I can use the war file without a license on Windows
          • It also means that giving a HeadlessException on Linux is ridiculous, when the problem is a missing license
        • A war file generated by the open source version of SoapUI does NOT require a license to be used
          • Learning point: Even if using (a licensed) Ready!API to design tests and virts, you should use SoapUI Open Source to generate the war - that way making it possible to use the war without licensing restrictions

        It would be good if someone from SmartBear could clarify/comment/confirm the above observations.
