[marky8264]

hey,
ich bin gerade dabei eine Anwendung mit Spring und Hibernate zu schreiben.
mein Problem ist jetzt folgendes:

Hier mein applicationContext:
[XML]
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
<property name="persistenceUnitName" value="xPersistenceUnit"/>
<property name="dataSource" ref="xDataSource" />
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
<property name="jpaVendorAdapter">
<bean
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
<property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
<property name="generateDdl" value="false" />
</bean>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate3.SpringSessionContext</prop>
</props>
</property>
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
[/XML]

Ich sitze jetzt schon den ganzen Tag dabei und kann dieses Problem nicht lösen. 🙁
