RE: [Wrapper-user] Sockets and desktop

[ender w. <end...@ya...>]

In short:
I wrote a java program that listens to a Server Socket
and when receives a message on the socket
it prints it on the screen in a Frame.
The program works fine when I test it in the Wrapper 
console. 

Next, I tried adding a shortcut of the .bat file
frok the bin dir to the my startup folder.
When I log on the wrapper console appears, and it
says: 
//////////////////////////////////////////
wrapper  | --> Wrapper Started as Console
wrapper  | Launching a JVM...
jvm 1    | Wrapper (Version 3.0.5)
jvm 1    |
////////////////////////////////////////

but my program does not start.
If I look at the log I actually see that there is no
entry for the current time, ie for the user logon
time.

Basically I would like to know if I am using the
wrapper improperly, and if I am, how do I make my
program start automatically short of making an exe and
placing it in the startup?
