Correction: Portals/Portlets are not new. Many people/companies use them. There are many experts on the subject. There isn't much activity in this forum because it's new to JavaRanch. But we're trying to change that!
Knowing the JSR spec like Jessica suggests is a good start, but the spec is new, and there are number of portals that don't conform to it, and are still worth knowing, so the situation isn't at all like it is with servlets.
It's still good advice, though: Get to know a portal (JetSpeed, Pluto, ...), use it, develop portlets with it, and you will get to understand the issues and problems that portals need to address. By the time you're done with that, maybe all important portals implement the spec, and you can take it from there.
