RE: Liferay 6.1 Beta4 on Mac OS

[Milan Palian, modificado hace 12 años.]

I just downloaded the community version 6.1 Beta4 Tomcat bundle. On startup on MacOS 10.5.8, all it says is:

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
	at java.lang.ClassLoader.defineClass1(Native Method)
	at java.lang.ClassLoader.defineClass(ClassLoader.java:676)

Anyone else run into this?

What JVM version do you have?

Juan Gonzalez P:

What JVM version do you have?

Apple only supports Java 1.5 on my notebook (Mac OS 10.5.8 with 32-bit Intel). Until I figure out what to do about it, I am using Linux with Java 1.6, where Liferay 6.1 works.

[Arno Broekhof, modificado hace 12 años.]

Working like a charm here.
( MacOSX 10.7.2, java 1.6.0_29 )

What version of MacOSX are you running? Leopard, Snow Leopard or Lion,
What version of java is installed? ( on a terminal window can you type: java -version )

If i am not mistaking java v1.5 was last shipped with macosx when the macs where still powerPC based,

you can also use the macports of Oracle for the java 1.7 preview edition.

I suppose that means I need Java 1.6 to run Liferay 6.1 ...

You could try downloading sources and compiling with JDK 1.5

In fact, latest sources have many solved issues since B4
