 <p>Click <span class="bold">Manage libraries</span> to create or update your JPA user libraries. Click <span class="bold">Download libraries</span> to obtain additional JPA implementation libraries.</p>
 <p>If Dali derives the incorrect schema, select <span class="bold">Override the Default Schema for Connection</span>. Using this option, you can select a development time schema for defaults and validation.</p>
