Missing plugin directory in jdk and jre downloads - linux

I just downloaded and installed the jdk1.5.0_12 update and the jre1.5.0_12 64bit on my linux(FC6 x86_64) machine and there is no plugin directory under jdk1.5.0_12/jre or under jre1.5.0_12/. What gives ? I want to install the java plugin on my firefox browser and it's not included in the download - please help.
