Hi ,

Fisrt of all, if you build/package your java service with Eclipse For Java, you can debug it there.

Secondly, did you try to call your java service using another tool like Fiddler or Postman ?

Cordially,

Hi

Thanks for the response.

These java services are part of pre-built package shared with us, hence it should be working properly and we should not need to debug, but still can you suggest me how to open the jar into eclipse project as these are compiled classes, do we need to de-compile the jar?

Secondly, yes I have tested the services using postman as well.

Hi ,

If' you've already successfully tested the java services with Postman then you don't need to try to de-compile the jar archive file.

There is another way to test the java services using Mobile Fabric :

  • click on Environments (the cloud image) if you have access;
  • click on Server (in Features);
  • click on Integration Services (in App Services);
  • in your Service Name (column Service Type is Java) , select the operation you want to test;
  • provide the input param values to test;
  • click Get Response.

If the issue is still there then you should open a ticket to the support.

Crodially,
