Is there a way to get a JDK or JRE as a regular package/archive? Like, I want to download a ZIP file and extract it into an arbitrary location and not have it make any system changes (e.g. updating the java.exe in the system32 folder, modifying registry settings, modifying what plugin is used when executing applets, etc.). Our computers at work are tightly controlled and maintained, but developers are permitted to install software (at their own peril). Accordingly, JREs are automatically installed/updated for us. Sooooo, in order to decrease the potential of conflicting with those installs, I wanted a non-install version of the JDK/JRE.
