spring data jpa and cxf dynamic proxy
i have the following setup for aip-persistence-context file:
Code:
<?xml version="1.0" encoding="UTF-8"?>

where the S2ServiceLocatorBean is a spring bean that uses an annotation (managed by a cxf dynamic proxy called jaxwsclientproxy) to call a service to return a datasource. code fragment below:
Code:
public class S2ServiceLocatorBean
{
// this is the jaxws client proxy created to call the service
// the annotation is processed using a BeanAnnotationPostProcessor and
// we use afterPropertiesSet and use Spring's ReflectionServiceFactoryBean to get the
// SEI (service endpoint interface ) to make a SOAP call to get the DB Info
@ServiceProxy(channel="locator")
LocatorDBInfoSvc locatorService;
public DBInfo getLocatorInfo()
{
LocatorGetDbInfoResponseT response = locatorService.submitLocatorGetDbInfo(input);
return new DBInfo(response);
}
}
the problem is when i use jpa:repositories along with EMF (entity manager factory) the line locatorService.submitLocatorGetDbInfo always throws NPE (Null Pointer Exception).
it's as if once spring-data-jpa is done with making proxy objects it won't allow the ServiceProxy beanannotationpost processor to do it's job.
any clues to why this happens as i find it quite interesting.
note : i also implemented the SmartLifeCycle on S2ServiceLocatorBean so it would be the first bean that's instatiated or destroyed....this also doesn't help.
