javac is the java compiler. You don't "run" programs with javac, you'd run them with java, so what are you actually trying to accomplish?

so javac isn't on your PATH then, or it's been uninstalled. What JDK were you using, and how was it installed?

Try "rpm -qa | grep -i jdk" and see if that gives you a package

right so presumably "rpm -qf jdk-1.7.0_07-fcs.x86_64" will list all the files including the location of javac, which woul dneed to be put onto your path

Setting up jdk-1.7.0_07-fcs :

1) su

2)
/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_07/jre/bin/java 2

3) /sbin/alternatives --config java
... And then select "jdk7".

There are 2 programs which provide 'java'.

Selection Command
-----------------------------------------------
* 1 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
+ 2 /usr/java/jdk1.7.0_07/jre/bin/java

Enter to keep the current selection[+], or type selection number: 2

is my path set??still i am able to compile programs

Well, usually the shown "/sbin/alternatives --install "
will take care of the javac command too.

Please try :
/sbin/alternatives --install /usr/bin/javac javac /usr/java/jdk1.7.0_07/bin/javac 2
