ZGo

ZGo is a Java applet which displays SGF. Examples, and instructions for how to use it in your own web pages, are at the Go Vortex home page. Current version is 2.0

You can see ZGo working on several Go blogs, like Chiyodad, Alejo's Tenuki, Go shodan challenge...

I use it for my national archive - Ian

Supports for SGF4
Supports for multiple games & problem collections in a single SGF file.
The ZGo jar archive can be used as stand alone application.
