Hi,

after download of mediaplayer.zip from https://github.com/PeteManchester/MediaPlayer/releases to a Pi3 and unpacking the zip:

~/mediaplayer $ sudo ~/mediaplayer/run.sh Exception in thread "main" java.lang.UnsupportedClassVersionError: org/rpi/main/StartMe : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482)

is what I get.

Any ideas?

Thanks in advance

Hi,

Can you check the version of Java that you are using 'java -version'.

Looks like you don't have the required version of Java installed.

Thanks,

Hi,

thanks for the quick reply. I‘d given the Java version in the Subj. line. It‘s the Oracle JDK giving java -version 1.7.0_60 (instead of the _40 in your guide).

Best regards,

PS: That‘s the default Oracle Java JDK currently installed on an up-to-date Raspbian stretch.

Sorry I missed that, it was early in the morning. The documentation is out of date now, the MediaPlayer requires at least Java 8, I will update the docs.

Let me know how it goes.

Thanks,

Pete.

Thanks, I‘ll try later this evening and report, but guess that‘s a downhill battle.

Hi Pete,

thanks a lot, MediaPlayer is running fine! Is there a channel we could discuss feature questions?

Best regards,

Robert
