I will pay for who can help me with this applet

Applet probably needs to be signed

Which he says it is :o)

It sounds vaguely like a "running lengthy operations on the event dispatch thread" kind of thing. Where are you making your server calls? Does the applet actually crash or does it just lock up until the server calls have completed? Does it use network connections when running successfully in application mode, or is it only using the local machine in application mode?

The answers to the above might provide the answer. Failing that it's a case of digging into your code.

thaks for yours anwswers..

harmmeijer: the applet is signed ok, I dont think that is the problem...

itchyscratchy: the server calls are made from start() method. The applet is crashed during its sending files to FTP server, when finish, the applet look ok.

The class I use is FtpBean: http://www.geocities.com/SiliconValley/Code/9129/javabean/ftpbean/

(I test too with apache commons-net, and the same effect...)

The ftp is Filezilla in localhost.

This is the code, I explain a little:

The start() method calls iniciar() method where its is defined the array of files to upload, and connect to ftp server. The for loop on every element of array and uploads a file on subirFichero() method.

Basicaly its this.

The HTML code is:

<applet

codebase = "."

code= "revelado.Upload.class"

archive = "revelado.jar"

name= "Revelado"

width= "750"

height= "415"

hspace= "0"

vspace= "0"

align= "middle"

>

<PARAM NAME="usern" VALUE="username">

A couple of things in your test program:

Firstly,

while(fi.read(b)>-1){

You are not saving the number of bytes actually read in, hence when you write the buffer out you're writing the entire byte buffer each time, even though potentially only a single byte has been read in.

Secondly, you are updating GUI in non event thread in the code:

test.this.setVal(i);

setVal should ensure that the GUI update is done in the event thread using SwingUtilities.invokeLater - this could easily be causing your crashing.
