title: Changing default field types when generating entities from tables
body: <p>Using Eclipse Dali tools to "<a href="http://www.eclipse.org/webtools/dali/docs/3.2/user_guide/tasks006.htm#BABBAGFI" rel="nofollow">generate entities from tables</a>" but I want to change the default table column / entity field mappings. </p>
  
  <p>For example when column type is <strong>int</strong> the tools generate the following mapping.</p>
  
  <pre><code>@Column(name="QUANTITY")
  private int quantity;
  </code></pre>
  
  <p>But when the quantity is nullable, it makes problems during the validation phase, so I change it to: </p>
  
  <pre><code>@Column(name="QUANTITY",  columnDefinition="int")
  private BigDecimal quantity;
  </code></pre>
  
  <p>Can this be configured globally?</p>
