    <p>I have a project which uses another project as a lib and I have Spring and Hibernate on both projects, the problem is that I need to map the classes from my first project to my second project.</p> <p>This is the exception I got:</p> <pre><code>Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Usuario is not mapped [SELECT u FROM Usuario u WHERE usuario = 'abc' order by idUsuario desc] at org.hibernate.hql.internal.ast.util.SessionFactoryHelper.requireClassPersister(SessionFactoryHelper.java:180) </code></pre> <p>So I tried to map the classes in the persistence.xml, this way:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"&gt; &lt;persistence-unit name="default"&gt; &lt;class&gt;com.planner.pov.model.Usuario&lt;/class&gt; &lt;class&gt;com.planner.pov.model.LogWork&lt;/class&gt; &lt;class&gt;com.planner.pov.model.Responsavel&lt;/class&gt; &lt;class&gt;com.planner.pov.model.GrupoResponsavel&lt;/class&gt; &lt;class&gt;com.planner.pov.model.Cargo&lt;/class&gt; &lt;class&gt;com.planner.pov.model.TarefaBackLog&lt;/class&gt; &lt;class&gt;com.planner.pov.model.ItemBackLog&lt;/class&gt; &lt;/persistence-unit&gt; </code></pre> <p></p> <p>But there are so many classes to map, they are all chained... Is there a better way to do it?</p> <p>@EDIT</p> <p>applicationContext.xml</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"&gt; &lt;context:component-scan base-package="com.planner.pov" /&gt; &lt;bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /&gt; &lt;bean id="ConfiguradorDePropriedades" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"&gt; &lt;description&gt;The service properties file&lt;/description&gt; &lt;property name="location" value="file:AppConfig.properties" /&gt; &lt;/bean&gt; &lt;bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"&gt; &lt;property name="dataSource" ref="dataSourceLocal" /&gt; &lt;property name="packagesToScan" value="com.planner.pov" /&gt; &lt;property name="jpaVendorAdapter"&gt; &lt;bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"&gt; &lt;property name="database" value="${database}" /&gt; &lt;property name="showSql" value="false" /&gt; &lt;property name="generateDdl" value="true" /&gt; &lt;/bean&gt; &lt;/property&gt; &lt;/bean&gt; &lt;bean id="dataSourceLocal" class="org.springframework.jdbc.datasource.DriverManagerDataSource"&gt; &lt;property name="driverClassName" value="${driver}" /&gt; &lt;property name="url" value="${jdbc.url}" /&gt; &lt;property name="username" value="${jdbc.user}" /&gt; &lt;property name="password" value="${jdbc.pass}" /&gt; &lt;/bean&gt; &lt;bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"&gt; &lt;property name="entityManagerFactory" ref="entityManagerFactory" /&gt; &lt;/bean&gt; &lt;tx:annotation-driven transaction-manager="transactionManager" /&gt; &lt;!-- Configuração do LogWorkController --&gt; &lt;bean id="logWorkDao" class="br.javablocker.dao.LogWorkDaoImpl" /&gt; &lt;!-- Configuração do ClockMainController --&gt; &lt;bean id="clockMainController" class="br.javablocker.controller.PlannerClockMainController"&gt; &lt;property name="usuarioController" ref="usuarioController" /&gt; &lt;property name="logWorkDao" ref="logWorkDao" /&gt; &lt;/bean&gt; &lt;!-- Configuração do UsuarioController --&gt; &lt;bean id="usuarioDao" class="br.javablocker.dao.UsuarioDaoImpl" /&gt; &lt;bean id="responsavelDao" class="com.planner.pov.dao.ResponsavelDaoImpl" /&gt; &lt;bean id="usuarioController" class="br.javablocker.controller.UsuarioController"&gt; &lt;property name="usuarioDao" ref="usuarioDao" /&gt; &lt;property name="responsavelDao" ref="responsavelDao" /&gt; &lt;property name="logWorkDao" ref="logWorkDao" /&gt; &lt;/bean&gt; &lt;bean id="logWorkController" class="br.javablocker.controller.LogWorkController"&gt; &lt;property name="logWorkDao" ref="logWorkDao" /&gt; &lt;/bean&gt; &lt;/beans&gt; </code></pre>

    1. COMaybe [this](http://stackoverflow.com/a/1999380/778118) will help. My memory says you don't have to specify each entity if you want to use all the entities from a given location. Maybe [this](http://stackoverflow.com/a/1780362/778118) or [this](http://stackoverflow.com/q/1999307/778118) might help, too.

    3. COThanks for the answer! But if I use the tag <jar-file>MyProject.jar</jar-file> it'll only works if I have my project as a jar file, but what if I don't have it yet, I mean in case of testing?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
