can you share your code please?
well, even without looking at your code, it seems that you're just trying to access package that's not there.. so i guess you need to either create that package.. or... delete that line (in the beginning of the codes)

Here is the code. It works within netBeans. If I run it in the command window with javac, I get message "package org.jdesktop.layout does not exist"

/** Creates new form report2 */
public report2() {
initComponents();
}

/** This method is called from within the constructor to
* initialize the form.

dajiebuda do not do double posting! Stick to the original post and do not spread chaos over forum. I told you where you can find information to setup CLASSPATH and you should follow them. Why? Because if the not let you have NetBeans you would not know how to run simple Hello.java program from command line...
