title: Eclipse error "the import com.microsoft cannot be resolved"
body: <p>I am running Eclipse Luna 1a(4.4.1) on a Mac. This source line:</p>
  
  <pre><code>com.microsoft.sqlserver.jdbc.SQLServerDataSource;
  </code></pre>
  
  <p>gives this error: com.microsoft cannot be resolved to a type.</p>
  
  <p>I have the path to sqlserverjdbc.jar defined in class path variables:</p>
