1. Check the documentation link on the left navigation bar. I recommend the yearly subscription model.
3. The driver provided by your DB vendor or any other XA aware third party driver for your DB
4. This is currently outside EJB CMP spec and app server/DB specific. There are some alternatives for couple of databases. Check the CMP forum for details.
I went going through that documentation and also Jboss 3.0 workbook by Bill Burke and Sacha.
Please note that I am trying a example whose SQL script is given below
create table bands (
primary key (name, founder));
create table recordings (
sales NUMBER(10, 2),
primary key (title, bandName, bandFounder),
foreign key (bandName, bandFounder) references bands(name, founder));
I am getting SQL Duplicate-Column Exception please suggest where I am wrong by going through the files,
Or at present Jboss does not support composite primary keys(hope this is not the case!)
with best regards
