QuerySyntaxException: Unable to locate class
<p>I am using hql to generate an actual Java object of class JunctionManagementListDto. But I end up with the following exception on my console</p>

<pre><code>org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate class [JunctionManagementListDto] [SELECT new JunctionManagementListDto(c.siteId, c.name, c.ip, c.customer.id, zm.zone.name) FROM com.traff.hibernate.model.Controllers c, com.traff.hibernate.model.ZoneControllerMapping zm WHERE c.siteId = zm.controller.siteId  ]

<p>What is causing this exception and how can I solve it?</p>
