I have installed the JDK on Mac OS X v10.8 (Mountain Lion). When I upgraded it to Mac OS X v10.9 (Mavericks) and ran java -version in the terminal, it showed:
No Java runtime present, requesting install.
Then I manually installed the JDK (1.7) on my Mac. It seems that the installation worked fine. When the installation was done, I opened the terminal and typed java -version as well. It also showed the same error:
No Java runtime present, requesting install.
How can I solve this problem?
