problem with finding imported classes

Hi all, I have my class that uses the library org.apache.commons.net.ftp.FTP;
so when I compile my class I use this command
javac MyClass.java -cp commons-net-2.2.jar
(the folder contains MyClass.java, commons-net-2.2.jar, index.html)
So I compile without errors..
but when I put the applet in index.html (<applet code="MyClass.class"></applet>)

and I try to run the applet I get this console error:

Code:

---

java.lang.RuntimeException: java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClient
        at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
        at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
        at java.lang.Thread.run(Unknown Source)

---

why, I can I solve it?

Hi.
You need read this topic
How to Make Applets (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components).
You need to set all library, which you use in applet.
For example:
[code]
<applet code="TumbleItem.class"
codebase="examples/"
archive="tumbleClasses.jar, tumbleImages.jar"
width="600" height="95">
[code]
