The new abbreviation that sticks to the version 12c (is c for Cloud),and it means that the JDeveloper is an enabled Cloud development IDE.
One of the most interesting features of the JDeveloper 12c that worthwhile is its installer, it is very easy to install and runs on mac OS X operating system rather than its previous 11g versions series, avoiding much of boilerplate system configurations to just install it.
So let's see how we can install it on Mac OS, but first let us get the required software to complete the installation process successfully.
- Java Development kit 7 update 25+ or less, it is a critical piece of software that allows the installer to pass the prerequisites successfully. It could be downloaded from here.
- Download the JDeveloper 12c Generic installer the works on all platforms (it is a jar package).
That's all; let's now go through the installation process.
- First open your terminal, and type the following command:
You should make sure that your java version is version 7 pointed out in your system class path, if version is different, you should make your system class path includes the java 7 version.
If everything is okay then you will see output like the following:
- From the same terminal, change your directory to your JDeveloper downloaded jar file, for example I have downloaded the jar file inside a folder named “Oracle JDeveloper 12c (188.8.131.52.0) (Build 6668)” on my mac desktop. To begin installing the JDeveloper issue the following commands:
Then followed by:
If everything is going okay then you should see the following output:
Then the following screen will popped up, and the installation process begins. Choose your inventory, which will, includes your JDeveloper system preferences folder, and OS group permission. I have changed it from stuff to be everyone, and clicked Ok button.(This screen will appear only on mac OS, but if you are using windows OS, the wizard will pop up for the installation and the process will begin from the next step):
- On the next screens “Oracle JDeveloper studio installer”, it includes five wizard steps, click next on each of them till finishing the installation, and seeing the following screen:
- Click next and the summary page comes with all installation log, including three options as in the following figure, for me I have choose the first option.
- Click finish and JDeveloper will start with new splash screen as the following:
- After splash screen finished preparing JDeveloper components, the main IDE should open with a new and neat look and feel:
- From Tools menu item, click check for update menu, you can make your new JDeveloper 12c, most updated with required components, one of recommended components is jUnit component.
- After finished the updates, we need to create a default domain of Weblogic 12.1.2 bundled server, from run menu click "Start server instance":
- The Weblogic configuration dialog will appears to provide password, and other configurations:
- Click Ok button and the JDeveloper log, will contains all creation and running conversation entries, wait till you find your log ends with the following entries:
