The Oracle implementation is packaged into two different distributions: The Java Runtime Environment (JRE) which contains the parts of the Java SE platform required to run Java programs and is intended for end-users, and the Java Development Kit (JDK), which is intended for software developers and includes development tools such as the Java compiler, Javadoc, Jar, and a debugger.
I don't use java, but the above might be a clue, you may need to download & install the JDK for your distro.
(To run a program, I think it is, java <progname>.jar.)

yum install javacc

# yum search java
.. And if you think you can use openjdk :
# yum install java-1.6.0-openjdk-devel
Or version 1.7 : # yum install java-1.7.0-openjdk-devel

The Sun java6jdk : jdk-1.6.0_37-fcs


Setting up java : Post # 4 here ..
