Let say we have an atomic function Compare-and-Swap:
CSW(a,b,c)<
if (a==c){
c = b; return 0;
}else { a = c; return 1;}>
How do we use this CSW(a,b,c) to develop a solution to the critical section problem for n threads?
Thank you
just got it today. Had no experience at all before. Studied in 1.5 month
Books to read: HFE, spec, some mock exam. The exam is quite close to the mock exam in HFE
Do we have transaction in entity. If we do, do we have to finish the transaction before the method ends?

-Thanks
so they should specify that in the spec then. Like:

content:
The enterprise bean home and component interfaces, for session and entity only.

but they didn't say that
If we see that kind of question in the exam, what should we do?
From the spec:
The ejb-jar file must contain, either by inclusion or by reference, the class files of each enterprise bean as follows:

The enterprise bean class.
The enterprise bean home and component interfaces.
The primary key class if the bean is an entity bean.
The ejb-jar file must also contain, either by inclusion or by reference, the class files for all the classes and interfaces that each enterprise bean class and the home and component interfaces depend on, except J2EE and J2SE classes.
The Application Assembler must not package the stubs of the EJBHome and EJBObject interfaces in the ejb-jar file.


but, in the case of Message Driven Bean, there is no home, no component, so how can we include those files into ejb-jar file?

I just downloaded the Eclipse, but I couldn't use the debug funtion, it says something like:
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=JVMTI_ERROR_INTERNAL(113)
ERROR: transport error 202: connect failed: Connection refused ["transport.c",L41]
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510) ["debugInit.c",L500]
JDWP exit error JVMTI_ERROR_INTERNAL(113): No transports initialized

does anyone know how to fix it? I use Java 5.0
Thank you
