Running a UDPServer on cmd window

I have tried to make a UDPServer and complied it. Howver, it doesn't run while another file, DisplayIP.class works.
It casts the error like the picture below. So i thought, it might be a problem with my pahtes, yet, it still doesn't work.
How can i fix this?

JAVA_HOME:
C:\Program Files\Java\jdk1.7.0_03
CLASSPATH:
.;%JAVA_HOME%\lib\tools.jar
path:
;%JAVA_HOME%\bin

Is the class in a package? Remove the package statement for easier testing. Otherwise position the class file to reflect the package and include the package name with the class name with the java command.

command? ex)java UDP.UDPServer

You need to be in the folder that contains the UDP folder. The java command will follow the package path to find the class file.

Um.. I opened the command window in UDP folder which is package. and I typed like following:
---------------------------------------------------
C:\Users\Hongyun\workspace\MyDemo5\src\UDP>java UDP.UDPServer 1234
Error: Could not find or load main class UDP.UDPServer

C:\Users\Hongyun\workspace\MyDemo5\src\UDP>
-------------------------------------------------------
FYI, 1234 stands for the port number setting.
Of course my source starts with "package UDP;"

Oh.. I was stupid. I should have opened it outside of the package folder.
Thank you!! It was very helpful.!!
