NOTE: Before actually proceeding further, read the " Discussion" to this SDB for updates and contributions which may not yet have been accepted to be part of the main SDB. This way, one might even follow both procedures in a sequence, since the JDK and the JRE are installed in different directories, but only the latter is going to be used by your system (or whichever the symbolic link is pointing to).
jdk_Oracle, will be used for the symbolic link pointing to the folder where the Oracle Java Environment is located. With both the procedures given below, for JDK and for JRE installation, the same name, i.e. Installing both packages when they have the same version number is not (quite) useful. Differences with JRE installation should be clearer, should someone want to install just the Java Runtime Environment. The JRE installation is a shorter version of the JDK installation, therefore the procedure to install the JRE will be shown first. Java Development Kit (JDK): in addition to the Java Runtime Environment (JRE) above, it includes all the tools needed to develop, test and debug programs written with Java language.Java Runtime Environment (JRE): includes Java virtual machine), libraries, Java application launcher, web browser and in general everything should be needed to run programs written with Java language.On the Oracle Java website two versions are available for downloading: Here is a quick guide on how to install the newest and secure version. 5.4 Setting options specific for version of installed Java JRE (option)ĭue to Oracle (Sun) licensing policies, Java JRE cannot be included in the repositories of openSUSE anymore.5 Procedure with runtime environment only (JRE).4.4 Setting options specific for version of installed Java (option).4 Procedure with development kit included (JDK).3.2 Bash script to gzip manual pages and install update-alternative.3.1 Obtaining and installing the rpm package.3 Java Development Kit installation using Oracle's RPM.2 Java Runtime Environment Install using Oracle's RPM.
