Service Builder ext-spring Error creating bean with name 'myAppHibernateSes

[ton dev, modificado hace 11 años.]

i want to make a persistent layer for an existing table using service builder because i've read its doable.

i followed the example in Liferay in Action MEAP on service builder and

i copied the sample contents for ext-spring suggested in the book but when i deployed the application the exception is this

16:47:11,498 ERROR [ContextLoader:220] Context initialization failed

i guess it has something to do with spring,, i have no idea what's spring is

any suggestions how to correct this error??

[Jan Geißler, modificado hace 11 años.]

Well, Spring is a Framework which offers apart from other Modules:
Dependency Injection (Inversion of control pattern) , Portlet and Servlet MVC Framework, ..., .....
As for you error, you are trying to call a Method of an Abstract Class. To be more Precise: Spring is trying to call that method on initializing the ServiceContext of your application ;)
Bean:
myAppHibernateSessionFactory
Cause:
Invocation of init method failed
java.lang.AbstractMethodError

So it seems to me that:
com.liferay.portal.spring.hibernate.PortletHibernateConfiguration
is an Abstact class.
To be honest, I am not sure about this, because I've never tried to use Existing tables with Liferay ;)

ton dev:

    <bean id="myAppDataSourceTarget" class="com.liferay.portal.spring.jndi.JndiObjectFactoryBean" lazy-init="true">

        </property>
    </bean>

How is as400conn defined as a data source? The AbstractMethodException would seem to indicate that you're using either an invalid driver or one that Hibernate cannot determine the dialect for...

im using tomcat in defining datasource

this is the one i put in context.xml

<resource auth="Container" driverClassName="com.ibm.as400.access.AS400JDBCDriver" maxActive="100" maxIdle="4" name="jdbc/as400conn" password="password" type="javax.sql.DataSource" url="jdbc:as400://schema" username="uname" />

i used jt400.jar as my connector

what would be the right config when using as400... thanks for the help

[Jan Geißler, modificado hace 11 años.]

Are you Using DB2 as Database, is that Correct?

[ton dev, modificado hace 11 años.]

AS400, the old database being used in RPG programming, i tried using db2jcc4.jar, still no luck

[Jan Geißler, modificado hace 11 años.]

Don't know if AS400 is supported by LIferay (Hibernate). Maybe you should start investigating in that direction.
