|
|
Ever try to write a J2EE application accessing EJBs across a firewall? It can be messy, and developers often must resort to all kinds of workarounds, none of them particularly "neat." Developers often write a servlet to intercept HTTP requests and delegate them to EJBs, which is kind of a kludge. Another approach that uses tunneling technologies-such as RMI over HTTP-can entail a big performance hit. But there is a better way. You can solve this problem elegantly by using Java Secure Socket Extension (JSSE).

In particular, any problem in an enterprise system must be resolved quickly. In this article, Enterprise Java programming veteran Srikanth Shenoy reveals his best practices in EJB exception handling for faster problem resolution.
