I have a class FtpExample that calls a bean.
However for some reason when I package this class
as part of the "ftp" folder and I run the program it always gives me errors. Please note in the example FtpExample is inside a folder called "ftp".
Below is error:
C:\java-coding\ftpbean\FTP>java FtpExample
Exception in thread "main" java.lang.NoClassDefFoundError: FtpExample (wrong nam
e: ftp/FtpExample)

C:\java-coding\ftpbean-package-Example-inside\FTP>

It is strange the error is not given when I run the FtpExample class outside of the "ftp" package.
and thus instead of
package ftp;
I have statement
import ftp.*;
I want to use the "FtpExample.java" class inside the ftp package.

When you said this:
java FtpExample
you asked java to run a class named FtpExample.
So it looked thru its classpath and found a file named FtpExample.class. But when it loaded that file, it found a class named "ftp.FtpExample" instead.
I assume that you have the C:\java-coding\ftpbean\FTP directory (or ".") in your classpath.
The pakage name is part of the classname, and must be specified on the command line, as:
java ftp.FtpExample
You will also need to arrange your CLASSPATH to include the C:\java-coding\ftpbean directory. It probably is there since it seems to be able to find other things in that package when you run the version of FtpExample with no package.
 
I agree. Here's the link: http://aspose.com/file-tools
