Eclipse - "other driver default" issue, driver files not specified
<p>I am currently debugging my application in Eclipse and in the error logs it shows an error:</p>

<blockquote>
  <p>Driver problems - problem with driver "other driver default" (Error:
  driver files not specified in driver definition).</p>
</blockquote>

<p>I have no idea where to start looking for the issue in order to resolve it. How do I fix this issue?</p>
