Body
I have just started studying Spring framework. My current goal is to access database from my bean through JPA (TopLink** provider) on Geronimo server. But I can't overcome the problem of getting entityManagerFactory. The exception I get: <blockquote> java.lang.IllegalStateException: ClassLoader [org.apache.geronimo.kernel.config.MultiParentClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:spring-agent.jar </blockquote> The way I access it: <pre><code> <context:load-time-weaver /> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceXmlLocation" value="classpath:/META-INF/persistence.xml" /> </bean> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <bean name="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <tx:annotation-driven /> </code></pre> I will be very grateful if anyone can help me without using "-javaagent:spring-agent.jar" option. <hr> Searching a solution. First attempt. Following "axtavt" <a href="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/aop.html#aop-aj-ltw-environments" rel="nofollow noreferrer">advice</a>, I found example of specifying special class loader for your web application on Tomcat. It uses context.xml file for that purpose. Although my Geronimo uses Tomcat, I didn't succeed implementing context.xml. As is said in the next <a href="http://www.ibm.com/developerworks/java/library/os-ag-tomcat/" rel="nofollow noreferrer">manual</a> the alternative for context.xml for Geronimo is geronimo-tomcat.xml, but it's syntax doesn't provide any possibilities for changing classloader. I still need help! <hr>

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.
