Injection on server startup

[dittup]

Hi,

I am using ejb3. I need to inject references of delegate classes into the ejb so that it can call methods in the delegate. I need this to happen when jboss server start's up.

Is there any way I can do? I have all my bean definitions in a xml file named beans-ejb.xml.

I do not use tomcat as the webserver. Jboss is independent and acts as only a applicatiopn server. A beans.ejb3 file with the ejb's, delegates, dao and hibernate mapping files.

Thanks,
Aditya.P

What kind of file is this beans-ejb.xml (how are beans defined in it)?

here is my bean :

<beans>

 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
 <property name="driverClassName"><value>oracle.jdbc.driver.OracleDriver</value></property>
 <property name="url"><value>jdbc:oracle:thin:@dev-db.iagr.net:1521:dev</value></property>
 <property name="username"><value>owner</value></property>
 <property name="password"><value>ownerdev</value></property>
 </bean>

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 <property name="dataSource"><ref local="dataSource"/></property>
 <property name="mappingResources">
 <list>
 <value>Category.hbm.xml</value>
 </list>
 </property>
 <property name="hibernateProperties">
 <props>
 <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
 <prop key="hibernate.show_sql">true</prop>
 <prop key="hibernate.query.substitutions">true 1, false 0</prop>
 <prop key="hibernate.jdbc.fetch_size">15</prop>
 <prop key="hibernate.jdbc.batch_size">15</prop>
 <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
 <prop key="hibernate.cache.use_query_cache">true</prop>
 </props>
 </property>
 <property name="eventListeners">
 <map>
 <entry key="merge">
 <bean class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener"/>
 </entry>
 </map>
 </property>
 </bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 <property name="sessionFactory"><ref local="sessionFactory"/></property>
 </bean>

 <bean id="categoryDAO" class="com.rewardtv.rewards.dao.CategoryHibernateDAO">
 <property name="sessionFactory" ref="sessionFactory"/>
 </bean>

</beans>

Ok, you can easily get this objects into EJB's.
But why would you wan't to force something that ejb3 already supports.

All this stuff is already integrated into JBossAS + EJB3.

What you are using comes in handy with just a web container, not so much with a full blown app server.
