Hi

JMS is a specification and an API. There are several companies and organizations that have implemented JMS. This means that there are very different implementations around. Some allow e.g., a maximum message size of 100 KByte, some of 2 GByte, some are fast and some are reliable. Some store the messages in a file (or multiple files), some in a full fledged database, some allow to connect the DB of your choice with JDBC.

So if you are looking for a JMS, try to find out what your requirements are and then pick the product.

The best solution is to code to the spec (JMS API) and "plug-in" an implementation (e.g. trial-versions) and test or benchmark your solution.

Yes.



(your questions will get widely different answers, depending on the implementation)
