[Solved] Java 7 on Mac?

[kdean]

JD2 will use Java 7 if I double-click the JDownloader.jar, but doesn't see Java 7 at all if I launch from the application Icon. Java 7 is set to take priority in the Java Preferences. If Java 6 is disabled, JD reports no compatible version of Java is found.

Maybe it can help: http://board.jdownloader.org/showthread.php?t=41354

Java 7 is 64-bit only on Mac so the linked article doesn't apply. It looks like the application bundle needs to be recompiled to recognize the new oracle releases of Java.

JD installer brings its own java if not found! because apple no longer pre installs java!
If a java is installed, then JD will use that.
worked fine here. Please provide screenshots what you do?

[kdean]

Screenshots of what? I launch it, it uses Java 6 and not 7.

Does one need to reinstall after Java 7 is installed to have it work?

Also JD really needs to start storing preferences outside of the application bundle like a proper app such as in the Application Support folder in the Library so settings can be more easily preserved if one has to reinstall.

[Jiaz]

JD does still save all its information in JD folder because its not multiuser capable. Imagine you have 2 users on computer and user A updates jd , then you start with user B and it may no longer be compatible (the config files), because A updated its files, but not B

you can save the app/dmg and put it back after os reinstall. all needed info is saved in its app/dmg/folder
at the moment there are no plans /even no time..to change this.

The used java version is described in the app/dmg , the plist.info file.
maybe its not correct ( can't check without a mac). it should say java 1.6+
and then it's important what java you moved to top in java preferences

[kdean]

plist says 1.6+ and Java 7 is moved to top in java preferences.

I can confirm that JD is having problems with the (Oracle) Java versions on OS X (10.8.1). I have Java SE 7u7 JDK installed. There is no other active JDK/JRE installation in Java preferences:

$ java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)

Info.plist says:

<key>JVMVersion</key>
<string>1.6+</string>

When I launch JD a warning about an old version of Java is shown (17005000) and a browser window with the URL http://jdownloader.org/download/index?updatejava=1 is opened.

Looks like JD uses its own JRE from /Contents/PlugIns/jre.bundle. When I delete jre.bundle the warning is gone.

i double kdean's observation, JD prompts at every startup about outdated java version. here's a screenshot: **External links are only visible to Support Staff****External links are only visible to Support Staff**
on os x 10.6.8 only java 6 exists yet, but JD should use his own, isn't it?

[Jiaz]

Yes, I've already wrote email to my collegue to update the starter wrapper to use existing java if it exists. with upcomming update the warning will be temporarily disabled

wait for update

[kdean]

Should we be waiting for a "soon" update or "some time off in the future" update?

[Jiaz]

the message should no longer appear
for updated wrapper..I don't know...have to ask my collegue but hes currently on vacation, will be back next week

[roundsquare]

cool, it's gone, thanks a lot!

danke, es hatte wirklich genervt.

Hoffentlich wird dieses Jahr noch Java 7 für Mac OS erscheinen.

Java 7 ist schon veröffentlicht und steht zum Download bereit. Die Verantwortung für Java auf OS X ist von Apple auf Oracle übergegangen. Dort findest du aktuell Java SE 7u7.

[roundsquare]

ja, aber nicht für snow leopard.

[kdean]

With Apple more actively pushing people toward Java 7, is there any update on the application bundle detecting and using Java ?

While this doesn't affect Applications yet, it could be confusing if people install Java 7 and wonder why their app does not work.
