Hi ,
All these is from a site which i did not understand .
I understood this one
declaring an EJB component's method to be synchronized is a violation of the specification.
It's up to the container to take care of the object's life cycle and any concurrency issues.
But i could not able to understand this one :
Please let me know what is the meaning of the below line actually
The utility classes used within the EJB, such as the Collection classes, are allowed to use the synchronized keyword on its methods or blocks of code because these are all dealing with single instances.
