Q:

Runtime error on the exact same code on a different computer

I am working with a relativly unknown API. (ScrumWorks Pro) I am using it to export data into a SQL database. My issue is that I have moved my eclipse project from one computer to another and it stopped working. It continues to run fine on the old computer but I am getting the following error
Exception in thread "main" javax.xml.ws.WebServiceException: Failed to access the WSDL at: http://XXXXXXX:8080/scrumworks-api/api2/scrumworks?wsdl. It failed with:

It looks like while it's running its failing to connect to the host. But it works completely fine with the exact same credentials on the other computer.

A:

The problem was that the newer computer had a newer version of Java installed which broke parts of the API.
