The system cannot find the path specified - Problems

Question

I am having an issue that I am hoping someone can help figure out for me.
I am currently learning Java, and am working with the Beginning Programming with Java for Dummies book second edition. I have downloaded and am running the Java 6 program and am using the JCreator 3.5Pro that was recommended to run the Practice files for the Dummies book.
I have the practice files here:
C/Program Files/Xinox Software/JCreatorV3/My Projects
While trying to compile one of the practice files, I get this error message:
--------------------Configuration: MyNewProject - JDK version 1.6.0_21 <Default> - <Default>--------------------
javac: file not found: src_mynewproject.txt (The system cannot find the path specified)
Process completed.
**When I try to execute, I get this error message:**
--------------------Configuration: MyNewProject - JDK version 1.6.0_21 <Default> - <Default>--------------------
java.lang.NoClassDefFoundError: EchoLine
Caused by: java.lang.ClassNotFoundException: EchoLine

at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: EchoLine. Program will exit.
Exception in thread "main"
Process completed.
When I set up the new file, and the new class, I confirmed the file path.
I know most people will ask if I am absolutely certain I put in the code in properly, and yes I did. It was a matter of copying word for word, and punctuation. I did it 100% correctly. About 12 times. I have NO idea what this means, but I would REALLY REALLY appreciate any help on this.
Please keep in mind, I am slightly clueless, and really need to have any help dumbed down a bit. Lol.
As a side note, this isn't my first project, and I haven't had this problem before now.
thanks in advance. =)

Answer 1

So I wanted to clarify what I've done a bit more since I decided to redownload the dummies programs for the program and try again.
I will try to list my steps in order of what I did and see if I've gone wrong somewhere along the line.
I downloaded my project files from here: http://ca.dummies.com/store/product/Beginning-Programming-with-Java-For-Dummies-2nd-Edition.productCd-0764588745,navId-322469,descCd-DOWNLOAD.html
I unzipped them this time here: C:\Program Files\Java\jdk1.6.0_21\MyProjects\
I opened JCreator 3.5 and starting fresh, with all previous projects deleted and clicked on "Open Workspace". I chose "MyWorkspace.jcw". Right clicked MyWorkspace and chose "Add new Project" and then chose "Empty Project". As per the books instruction for the first project, I named it "MyFirstProject". My file path was: C:\Program Files\Java\jdk1.6.0_21\MyProjects\MyFirstProject. Which is where I upzipped the files. I added it to current workspace and clicked finish.
I then added a new class. As per the books instructions, I right clicked "MyFirstProject" and selected Add New Class. For the name, I used MyFirstJavaClass, which is what the book told me to do. My locations are the exact same as above. and I clicked on Generate new Method, as it told me to. Which it doesn't in the next few lessons, so I know this has nothing to do with it. For that and a few other reasons. Lol.
I clicked on Finish.
All I had to do was replace a single line of code. Not type it all in this time.
Here is what shows up on the screen:
class MyFirstJavaClass {
     * Method main
     * @param args
     public static void main(String[] args) {
          // TODO: Add your code here
I need to change the : // TODO: Add your code here
with the line:
System.out.println.("Chocolate, royalties, sleep");
When I do this, and compile project, I get this:
--------------------Configuration: MyFirstProject - JDK version 1.6.0_21 <Default> - <Default>--------------------
javac: file not found: src_myfirstproject.txt (The system cannot find the path specified)
Process completed.
AGAIN! But it worked a few days ago.
And when I execute, I get this:
--------------------Configuration: MyFirstProject - JDK version 1.6.0_21 <Default> - <Default>--------------------
java.lang.NoClassDefFoundError: MyFirstJavaClass
Caused by: java.lang.ClassNotFoundException: MyFirstJavaClass

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: MyFirstJavaClass. Program will exit.
Exception in thread "main"
Process completed.
I really hope the extra info helps someone help me!
thank you!
