Web Services Standards
It's getting close.
(I saw this on Panic From Fuzzy.)

I have a couple of these posters on my cube wall. This one looks somewhat complete. There are 62 little boxes that cover roughly what J2EE or CORBA covers. That sounds like a lot of stuff to learn. However, most of these stuff have a counterpart in previous generation, mature, technologies like CORBA:
| WS-* | CORBA | J2EE |
|---|---|---|
| XML | CDR | HTML |
| Schemas | IDL structs | Java type system |
| SOAP | GIOP | HTTP, JMS |
| WSDL | IDL | Java interfaces |
| WS-Transaction | OTS | JTA |
| UDDI | Naming, Trading Services | JNDI |
| WS-MS | ? | JMX |
| WS-BEPL | UML 2.0 | JBI |
| WS-Security | CORBA Security | J2EE Security |
| WS-Transfer | DDS | java.lang.Void |
| WS-Notification | Notification Service | JMS |
