I really don't know what the problem is. I followed several web postings about installing and settings of JDK/ JRE and also completed clearly on environment variables :Path & CLASS PATH I'm sure about that since i checked the cmd and it worked well. the same problem occured over and over again. I corrected on Library tab I add the Library list like this, But, I still have the same problem. Did I make a severe mistake? what should I do about this problem? still have JAVA problems
Please check the Java source directory configuration under Java Build Path, Source tab and Java Compiler version settings.
