I have tried this CyclicBarrier example and looks like Second Thread is not working completing after barrier.await() call ?

Is there something else happening, because I can see that JVM is still running but the last sysout statement in run() of the SeriveTwo class is not displayed in the console ?

Hi All,

I am new in Hibernate and i am doing these examples locally , but getting below error for many-to-many mapping:



Below are my code files

Student.java



Course.java



Here are the hbm files for both the above java classes

Student.hbm.xml



Course.hbm.xml



And finally my Testing class



Am i missing something or have i added something extra in hbm files ?
I was able to explain similar things , but i was thinking if there is any other disadvantage of it.

One of the interviewer asked me this question about Generics that Why they are made compile time validations ?

Any thought on this ? I have discussed with my friend that possible reason can be "It is runtime(which will be then part of JRE validations) then legacy code has to be changed".

Are you sure that you will let user upload the file based on the Pages ? Or you have some some size limit for uploaded file ? If that is Size which matters then you look for javascript code , what Ulf suggested is good .

Can you elaborate what all you tried and how exactly you are trying so that we can understand your requirement ?

Is it simply to fetch total Count / Per Page records = total pages (Can be done by Ajax call to get DB call and return final total number of pages ) .
