![]() ![]() Select JDK 1.4 and 1.4.2, and install it to default location via Pacifist's context menu (see screenshot).Yeah, it is still available, but Apple doesn't make live easy for Java developers these days: Do not install this package (as it will overwrite your existing Java versions)! See next step instead > cd /System/Library/Frameworks/amework/Versions/ ![]() E.g, in the terminal (with admin rights): ![]() Remove symbolic links in /System/Library/Frameworks/amework/Versions/ pointing from 1.4.* to 1.6 (otherwise, the 1.6 JDK will be overwritten). ![]() However, on OS X, you'll have to follow the hints explained at and repeated here for your convenience: So, I had to install JDK 1.4, which probably is no problem for Windows and Linux users. Strictly compatible with this environment.Simply making a selection on the 1.6 JVM in the list compatible JREs in Preferences / Java / Installed JREs / Execution Environment / J2SE-1.4 doesn't help (I tried to clean the projects, but 1.6 is not strictly compatible, thus clean doesn't help here). There are no JREs installed in the workspace that are Unfortunately, this JRE is not strictly compatible to J2SE-1.4, as I have learned from this error message:īuild path specifies execution environment J2SE-1.4. On OS X 10.6, JRE 1.4 is no longer installed, instead, version 1.4 points to 1.6. withīundle-RequiredExecutionEnvironment: J2SE-1.4specified in its manifest. The Control Panel will also enable you to manage more advanced options related to Application Installation, Secure Execution Environment, Java Console, Debugging and a host of Advanced Security Settings related to certificates and data transfer encryption.Īll things considered, Java for OS X is the thing that makes it possible for any application created using the Java framework to run on any Mac, with an interface that makes it look like a native app.Today I tried to compile a project requiring J2SE-1.4, i.e. Using the same panel, you can also check for newer versions of Java and view and manage the Java runtime versions installed on your Mac via the Java Runtime Environment Settings window. This panel enables you to adjust the runtime network settings, as well as manage the temporary internet files stored by Java on your Mac's hard drive. Java for OS X also comes with a Control Panel that can be opened via the System Preferences window, using the Java preferences pane. Thus, if the developer takes the time to make sure that the OS X look is set as the default for utilities distributed on the OS X platform, the end user will not be able to know if they are built using Java or not. On account of Java being the only framework with an embedded graphical toolkit, besides Cocoa, Java apps can be designed to provide Mac users with interfaces almost identical to those available in native OS X applications. Java for OS X follows the “Write once, run anywhere” tag line of the Java runtime and this means that developers do not need to make any type of adaptations or modifications to their Java apps in order for them to run on a Mac computer.īecause Java for OS X is so easy installable and the operating system will notify you to install it right away the first time you're trying to run a Java application on your Mac, developers that use it to create their applications can start distributing them on the Mac platform right away. įurthermore, it also brings an astounding amount of new applications to the Mac platform, all ready to use and compatible with all macOS releases, past and present. The newer Java packages are maintained by Oracle, therefore it is recommended to use Oracle's Java JRE. Java for OS X has been created to mix OS X's advanced technologies and Java's adaptability and omnipresence on almost all software platforms out there. Java for OS X is an Apple vetted Java environment, designed to be as highly integrated as possible within its own operating system. ![]()
