If you are not sure whether you have Oracle's JDK or JRE installed correctly, please confirm by doing the following: - Run a complete directory search (using the 'All File and Folders' option if available) on your drives for the occurrence of 'jdk' in the filename.
- To confirm correct JRE installation , run a complete directory search (using the 'All File and Folders' option if available) on your drives for the occurrence of 'jre' in the filename.
- If your results retrieve a folder with the name 'jdk' immediately followed by a series of version numbers (for example, jdk1.5.0_06), then your Sun JDK has been installed. You should double-check the contents of this folder to ensure that the installation files are intact. If you are unsure about this, proceed to step 3 to re-install the Sun JDK. Otherwise, proceed to step 3 to check that your JAVA_HOME environment variable has been set correctly.
- If your results retrieve a folder with the name 'jre' immediately followed by a version number (for example, jre6), then your Sun JRE has been installed. You should double-check the contents of this folder to ensure that the installation files are intact. If you are unsure about this, proceed to step 4 to re-install the Sun JRE. Otherwise, proceed to step 4 to check that your JRE_HOME environment variable has been set correctly.
- If you do not retrieve results as explained above, then it is highly likely that your Sun JDK or JRE has not been installed.
