    Default Package x does not exist????

    Hi

    I'm new to Java but not new to coding in general - I have a background in C programming. However, this error is driving me nuts! I have my environment variable CLASSPATH set to my NetBeans projects folder, and I've set the classpath in NetBeans to the same folder. I've built a test lib there called MyLib, but when I try and import that lib from another package with 'import com.domain.mylib.*;', I get the error saying the package doesn't exist! I'm probably making a rookie error here, but any help most welcome.

    The java programs use the CLASSPATH variable to find class definitions. The CLASSPATH should be the location of the class files like a folder or a jar file. It won't look for jar files to search. The path to the jar file must be in the classpath. For example:
    java.exe -cp .;acm.jar ClassName


    I don't know how to configure your IDE.

    So, does CLASSPATH need to be set to the exact folder holding the .class files? The book I'm working through seems to suggest I just need to set CLASSPATH to the folder holding all my packages.

    If the class files are not in a jar file, then the CLASSPATH needs to point to the folder containing the folder that is the head of the package name. Given package= com.mystuff, the CLASSPATH should reference the folder that contains the com folder. CLASSPATH + package name = full path to the class file.
