Well, it would be quite nice to get some more information. Of course anyone who wants to help you could search for this .jar file and maybe someone will guess that it is related to some O'Reilly book, but this could (way easier) be mentioned by you.

While I don't have this book (and therefore no access to the .jar file), I can't really help you without further infos. I found some example code that I could download, but the archive contains only .java files. So have you created the package by yourself?

The exception that is thrown is allready telling you what's going on. You trigger some event that refers to some function of the SMTPClient class, which is not known. This might be caused by some missing library. Just try to unpack the .jar file (if it doesn't work directly rename it to a .zip archive). You will find some folder META-INF which should contain the manifest.MF file. This file should contain some information, like the class to run as the main. Is there some line starting by "Class-Path:"? If so, you have to ensure that these files or (relative) pathes are accessible.

Best regards,
Herr K.

Where did you get the jar file? It appears to be missing a class definition file.

[lse123]

Manifest-Version: 1.0
Class-Path: lib/mail.jar
Created-By: 1.6.0_15 (Sun Microsystems Inc.)
Main-Class: SMTPClient

this reads is it correct? book [ch 19 / file name same] oreilly:
Java Network Programming, 3rd Edition
but modified code myself.

may zip file/folders and attach it to try it you?


in shortcut
target:"C:\Users\User\Documents\TextBooksDataFiles \Java Network Programming, 3rd Edition\jnp3examples\examples\19\SMTPClient.jar"
startin:"C:\Users\User\Documents\TextBooksDataFile s\Java Network Programming, 3rd Edition\jnp3examples\examples\19"
the jar is in the
C:\Users\User\Documents\TextBooksDataFiles\Java Network Programming, 3rd Edition\jnp3examples\examples\19\lib\mail.jar

only from running [CLI] the- java SMTPClient .class -email delivered

[lse123]

I attach without mail.jar in .../lib/ , well?

[Norm]

Yes, the manifest looks ok. Without the correct Main-Class: line, the JVM wouldn't be able to start the program.
When you look in the jar file, do you see the file: SMTPClient$SendAction$1.class

modified code myself

Did you create an anonymous class in SendAction?

Just downloaded your zip file. I searched the .jar file with a tool I have and got this report:

#Searching C:\Documents and Settings\Owner\My Documents\Downloads\SMTPClient\SMTPClient.jar for SMTPClient
SMTPClient
SMTPClient$1
SMTPClient
SMTPClient$2
SMTPClient
SMTPClient$3
SMTPClient
SMTPClient$4
SMTPClient
SMTPClient$SendAction
SMTPClient
SMTPClient$SendAction$1 >>>> class NOT found! <<<<
SMTPClient$UpdateListener
SMTPClient

# Found 8 classes. 1 NOT found.

How are you generating the .jar file? You need to add the missing class

I run
java -jar SMTPClient.jar // run from CLI
simple send email APP[GUI], but when press send button appeared:

  C:\Users\User\Documents\TextBooksDataFiles\Java Network Programming, 3rd Edition\jnp3examples\examples\19>java -jar SMTPClient.jar
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: SMTPClient$SendAction$1

Your SMTPClient class has a nested class named SendAction which has an anonymous inner class (I guess it's an implementation of the ActionListener interface, but that's just a guess). That class is not stored in your .jar file.

kind regards,

Jos

I added SMTPClient$SendAction$1 and now works, thks!

in the above class name "$" show inner classes? may included in any order in->...?

jar cmf SMTPClient.mf SMTPClient.jar SMTPClient.class SMTPClient$SendAction.class SMTPClient$SendAction$1.class SMTPClient$UpdateListener.class SMTPClient$1.class SMTPClient$2.class SMTPClient$3.class SMTPClient$4.class SMTPClient.java

[Norm]

You can use a wild card (*) in the jar statement: SMTPClient*.class vs the explicit list which can change if you add another anonymous class.

[lse123]

What you mean "which can change if you add another anonymous class. ", are you mean use same statement to recreate jar, in case modify file.java?

[Norm]

The compile names the anonymous classes it generates. It's possible for it to create one that is not listed in the list of class files you are loading into the jar file. If you use a wild card char to select the files to add, you will pickup all classes, not missing any.
