Hi all,
I have some troubles running spring on GAE for a particular configuration.
When I run this config on my local machine I have logs in the console that
indicate that it works. When I deploy it on GAE I have a null pointer
exception because PersistenceManagerFactory is null which is not the case on
local. (logs are in the doPost method)
Has someone already tried to use Spring MethodInvokingFactoryBean ?
Here it the code, thanks for any help

applicationContext.xml :
<context:component-scan base-package="com.mypackage.jdo"/>
<context:spring-configured/>
<context:annotation-config />
<bean class=
"org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"
/>
<bean class=
"org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"
/>
<bean id="pmf" class=
"org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="staticMethod">
<value>javax.jdo.JDOHelper.getPersistenceManagerFactory</value>
</property>
<property name="arguments">
<value>transactions-optional</value>
</property>
</bean>
<bean id="persistenceManager"
class="com.mypackage.jdo.PersistenceContextManager">
<constructor-arg>
<ref bean="pmf"/>
</constructor-arg>
</bean>
where com.mypackage.jdo.PersistenceContextManager is:
import javax.jdo.PersistenceManager;
import javax.jdo.PersistenceManagerFactory;
public class PersistenceContextManager {
protected PersistenceManager pm;
public PersistenceManager getPm() {
return pm;
}
public PersistenceContextManager() {
super();
}
public PersistenceContextManager(PersistenceManagerFactory pmf) {
pm = pmf.getPersistenceManager();
}
}
then in a servlet I have:
@Resource(name="persistenceManager")
private PersistenceContextManager pmf;
public void init(ServletConfig config) throws ServletException {
super.init(config);
ServletContext servletContext = config.getServletContext();
WebApplicationContext webApplicationContext = WebApplicationContextUtils
.getWebApplicationContext(servletContext);
AutowireCapableBeanFactory autowireCapableBeanFactory =
webApplicationContext
.getAutowireCapableBeanFactory();
autowireCapableBeanFactory.configureBean(this, "persistenceManager");
}
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException {
...
...
if (pmf != null) {
log.warning("pmf not null");
}
else {
log.warning("pmf is null");
}
PersistenceManager pm = pmf.getPm();
Transaction tx = pm.currentTransaction();
try {
tx.begin();
pm.makePersistent(myObjectToPersist);
tx.commit();
}
finally {
if (tx.isActive())
{
tx.rollback();
}
...
}
