If an app or webpage you want to use asks you to install Java software, you can download the current version of Java for OS X directly from Oracle's website. Note: You can also download legacy Java SE 6 from Apple if you’re using an app that specifically requires this unsupported, out-of-date version. This may be tough as Java 6 on the Mac was only provided by Apple. Oracle/Open JDK didn't take over to providing binaries until Java 7. Do you specifically need Java 6 or can you run it with a later version of Java?
While launching, Dreamweaver (13.2 and earlier versions) prompts you to install Java SE 6 Runtime.
Java SE 6/SE 7 Runtime is installed on the computer.
In Dreamweaver 2014, the prompt does not appear when you launch Dreamweaver. However, you are prompted to install Java SE 6 runtime while logging in to PhoneGap Build service (Site > PhoneGap Build Service > PhoneGap Build Service).
In the pop-up window that appears, click Install and follow the onscreen instructions to install Java SE 6 Runtime.
In Dreamweaver 2014, you can't log in to PhoneGap Build service without installing Java SE 6 Runtime.
Important: Ensure that you install Java SE 6 Runtime only by clicking Install in the pop-up window. If you install Java SE 6 or 7 Runtime through any other means (for example, by directly accessing Java.com), Dreamweaver could still display the prompt.
Even if you have installed Java SE 7 Runtime, you still need to install Java SE 6 Runtime as described above.
If you continue to see the prompt even after installing Java SE 6 Runtime as described above, perform the following steps:
Dreamweaver displays such a prompt because, when you update to Mac OS 10.9, Java SE 6 Runtime on your computer gets uninstalled.
