Have you signed up with a payment processing provider yet? There is no standard Java API for that, so the proprietary API of whichever one you work with determines some of this.

Other than that, I wouldn't think that the decision between Tomcat and JBoss, and whether or not to use EJB, depends in any meaningful way on the choice of payment processing company.

hi,
is it necessary and safer to use EJB's for online money transactions or a servlet page is sufficient to direct the data from server to payment processor.what do you suggest .is jboss a stable server than tomcat.

thanks in advance.

Isn't that exactly what we talked about here?

Laks,

There really isn't a clear-cut answer to the questions you are posing. Ultimately, a lot of it comes down to personal taste.

I find that using a commercial/open source Java EE 5 application server like JBoss, GlassFish or WebLogic with EJB 3 is a lot easier in terms of a learning curve and configuration (perhaps also using Seam). The customers who choose Tomcat (perhaps with Spring) often have a very strong open source bend, create their own frameworks/APIs, want flexibilty and create their own solution stack (perhaps with iBATIS, Quartz, Spring JDBC, AspectJ etc). I also have customers that integrate EJB 3 with Spring on a full-scale Java EE application server where they need Spring features while leveraging container features/simpler application configuration. As mentioned, it is also possible to use EJB 3 with Tomcat utilizing OpenEJB (this is also surprisingly popular).

Hope it helps,
Reza
