I read the descriptions and reviews of the book on amazon.com. The questions that I have are about some acronyms that I have not seen before and what they mean. I know EJB stands for Enterprise Java Beans but in the text description the is a reference to �EJB QL� What does the �QL� stand for? The other two that I have not seen before is �SwA� and �WSDL�. Could you give a brief explanation of each of the three?

not sure about EJB QL - probably stands for Query Language?if I had to guess I would say its a way to query data beans for their data in a way that resembles database access with SQL
WSDL stands for Web Services Definition Language - its an XML format and specification for describing units of processing that can be accessed using SOAP, the simple object access protocol - SOAP is an XML format for swapping data and making RPC calls (remote procedure calls) - RPC is a way to call methods or procedures across the network so that you can create distributed applications. RMI is a kind of RPC i guess.
anyway, in WSDL you describe where the object is (like looking up the object in the RMI registry) what it is called, and what the methods are called and what parameters they take.
not sure what SwA is

EJB QL is a query language for portable EJB finder methods - new for EJB 2.0.

Does anyone know how well the book covers using calling database functions from CMP beans? I know that's supported in EJB 2.0 but I haven't seen a lot of discussion.

I am constantly struggling with acronyms also . They really get out of hand at times.
 
It is sorta covered in the JavaRanch Style Guide.
