Currently there is only a 64 bit java browserplugin in the blackdown
package, and this is unstable! If you want java support in for example
firefox, than you have to use the firefox-bin package (32bit).

To see the available java plugins:

	eselect java-nsplugin list

and here is the thread, why the 64bit java plugin is not in the obove list:
	http://forums.gentoo.org/viewtopic-t-552110.html

To use the unstable 64bit blackdown java plugin, you have to link the
libjavaplugin_oji.so manually.
