Examples with Singleton javax.ejb.Singleton used on opensource projects

Example 1 with Singleton

use of javax.ejb.Singleton in project Payara by payara.

the class SingletonHandler method setEjbDescriptorInfo.

/**
 * Set Annotation information to Descriptor.
 * This method will also be invoked for an existing descriptor with
 * annotation as user may not specific a complete xml.
 * @param ejbDesc
 * @param ainfo
 * @return HandlerProcessingResult
 */
protected HandlerProcessingResult setEjbDescriptorInfo(EjbDescriptor ejbDesc, AnnotationInfo ainfo) throws AnnotationProcessorException {
    EjbSessionDescriptor ejbSingletonDescriptor = (EjbSessionDescriptor) ejbDesc;
    Class ejbClass = (Class) ainfo.getAnnotatedElement();
    Singleton singleton = (Singleton) ainfo.getAnnotation();
    // set session bean type in case it wasn't set in a sparse ejb-jar.xml.
    if (!ejbSingletonDescriptor.isSessionTypeSet()) {
        ejbSingletonDescriptor.setSessionType(EjbSessionDescriptor.SINGLETON);
    }
    doDescriptionProcessing(singleton.description(), ejbDesc);
    doMappedNameProcessing(singleton.mappedName(), ejbDesc);
    doSingletonSpecificProcessing(ejbSingletonDescriptor, ejbClass);
    return setBusinessAndHomeInterfaces(ejbDesc, ainfo);
}
