Interview Question: What is re-entrant. Is session beans reentrant. Is entity beans reentrant?
By: Ash Printer Friendly Format
Answer:
If we define the entity bean as being reentrant, multiple clients can connect to the Entity bean & execute methods within the entity bean concurrently. Container takes care of synchronization. If we define the entity bean as non-reentrant and many clients connect to it concurrently to execute a method, exception is thrown .
