Thread: java.lang.NoClassDefFoundError Help

Hello Everyone !
I want to run a java program on a server...
if i create a HelloWorld.java
it is comipled and run without problems

javac HelloWorld.java
java HelloWorld

But if i want ro run my programm that has 2 classes and a jar file (created in Eclipse from a dosen of packages)
the compilation doesn't throw anything but when i try to run it its throwing java.lang.NoClassDefFoundError
the way i compile and run is as follows:

javac  -classpath ffann.jar  *.java
java    -classpath ffann.jar  MyClass

Any Help is appreciated...!!!

you "shorten" the way too fast....
1) javac *.class
2) jar cvfe myjar.jar myEntry *.class
3) java -jar myjar.ja

..sorry for the missing r in 3) due to my keyboard-troubles. The r always needs a hefty press
3) java -jar myjar.jar

Thank you!
I will try it tonight and post the results....
However, i thought that javac creates the classes..
at the begining I have 2 java files(one of them has the main function) and one jar file (as external library)
so, first of all i have to compile the source code from File1.java File2.java with ffann.jar library
