Thread: Error installing Spoon on FreeBSD

    Default Error installing Spoon on FreeBSD


    I'm installing Kettle 2.4.0 on FreeBSD v6.1-i386, with JRE 1.4.2.

    java version "1.4.2-p8"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-p8-root_12_mar_2007_13_09)
    Java HotSpot(TM) Client VM (build 1.4.2-p8-root_12_mar_2007_13_09, mixed mode)

    We installed swt and firefox software on our FreeBSD machine because it was in some postings.

    I get the following exception. Any suggestions on this?

    Regards Rob

    Exception in thread "main" java.lang.UnsupportedClassVersionError: org/eclipse/swt/widgets/Composite (Unsupported major.minor version 49.0)

    It seems the swt library you use was compiled with a java 1.5 version. That gives your specific error message (you can look ik up via any search engine).
    I'm pretty sure the swt version in the kettle distribution is a 1.4 version or I and a few other people would also get it.

    So can you check whether you're not overriding the swt libraries somewhere with other versions.
    Another solution would be to run using a JDK1.5 (1.5 can read 1.4 class formats, but not the other way around).
