Help using AbstractStatelessSessionBean
Can someone explain how to use the AbstractStatelessSessionBean class. In particular what does the setBeanFactoryLocatorKey do and what is it for? I keep getting the below exception when I try to access it.
CODE
public class SearchServiceEJB extends AbstractStatelessSessionBean implements com.invest.common.business.ISearch
{
private ISearch searchService;
/* (non-Javadoc)
* @see org.springframework.ejb.support.AbstractStatelessS essionBean#onEjbCreate()
*/
protected void onEjbCreate() throws CreateException {
//Get a reference to the bean factory and to the POJO service implementation
searchService = (ISearch) getBeanFactory().getBean(
Constants.SEARCH_SERVICE);
}
public List searchAssets(Map searchCriteria){
return searchService.searchAssets(searchCriteria);
}
/**
* Override default BeanFactoryLocator implementation
*
* @see javax.ejb.SessionBean#setSessionContext(javax.ejb. SessionContext)
*/
public void setSessionContext(SessionContext sessionContext) {
super.setSessionContext(sessionContext);
setBeanFactoryLocator(ContextSingletonBeanFactoryL ocator.getInstance("serverContext.xml"));
setBeanFactoryLocatorKey("serverContext");
}
}
