Hello!
I am using a Service A, which is using the services from another service B,
but the Service B is null if i am calling a method from my Service B within
the class of Service A.
public class ServiceA {
@Inject
ServiceB serviceB;
public void someMethod(){
serviceB.doSomething();
}
}
but tapestry reports a nullPointer exception. the debugger shows me, that
serviceB is null. But if I am using serviceB from a normal page class,
serviceB is not null / and useable.
in my case, service A is the groupService, and service B the featureService.
I am declaring both Services in my ApplicationContext.xml
<bean name="featureService"
class="com.airwriting.service.data.FeatureService">
<property name="baseFeatureItemDAO" ref="BaseFeatureItemDAO" />
<property name="baseFeatureDAO" ref="BaseFeatureDAO" />
</bean>
<bean name="groupService"
class="com.airwriting.service.data.GroupService">
<property name="groupDAO" ref="GroupDAO" />
<property name="groupUserDAO" ref="GroupUserDAO" />
<property name="userDAO" ref="UserDAO" />
</bean>
hm...
