Java JDK - Found in Eclipse but not CMD

When opening Eclipse I can write and run programs in Java, but when I enter javac programname.java, it says the file can not be found.

In short: eclipse is finding the jre7 but cmd (even after making sure file was in the path cmd was looking in), cmd wont execute the programs.

How can I fix this?

Seems to be your java installation is corrupted. I think you should reinstall java. also You should ensure that you're installing the right jre for your architecture.

I believe your environment variable is not set properly.

If you are using windows then create a System Variable JAVA_HOME with the path of the jdk

JAVA_HOME = C:\Program Files\Java\jdk1.7.0_45

Then add this in the Path variable %JAVA_HOME%\bin

If you are using Linux then do the following :

  1. Open the bash profile

$vim /etc/profile

And at the end of the file include the following lines. Wherever you have unzipped the java directory add that path only.

  1. export JAVA_HOME=/usr/java/jdk1.7.0_45

  2. export PATH=$PATH:/usr/java/jdk1.7.0_45/bin

For other shell's in Unix , Have a look at the JDK Doc.

Eclipse does not require "javac" to compile Java source files since its JDT project supplies a compiler of its own. It's entirely possible that you do not have javac--it requires installing the JDK, not just the JRE that Eclipse itself requires--and that it would not be on your path as a result.
