    @alfirus remove the look and feel iin the unicentaopos.properties and you should be sorted.

    main reasons for this error are;
    1 Same JRE version is used to compile and run the java program
    2 You are running java class from the classes directory and package is provided as directory.
    3Your java classpath is set properly to include all the dependency classes
    4You are using only file name without .class extension while running a java program
    5Java class main method syntax is correct
    As I asked above what java version are you using?
