Signed Java Applet

Question

0 down vote favorite
I have written an applet with Netbeans. When I click on Clean and Build then Netbean create a jar file "Test.jar" and also another folder called lib in the same directory. I've signed the Test.jar. Basically this applet upload files to server with FTP. So when Applet loads into browser then I am able to select files but when I click on upload then it stops. So my question is:
1. Have I also need to sign all dependent jar files?
2. My directory structure is as follow:
C:\AppletPage.html C:\Test.jar C:\lib
and code in html file is as follow
<applet code="UploadGUI.class"
archive="test.jar"
width=400 height=400></applet>Please advice me where am I wrong?
Thanks in Advance

..lWhen I click on Clean and Build then Netbean create a jar file "Test.jar" and also another folder called lib in the same directory. I've signed the Test.jar. Basically this applet upload files to server with FTP. ..If you deploy the applet in a Plug-In 2 architecture JRE and launch it using Java Web Start - it can be sand-boxed.
..So when Applet loads into browser then I am able to select files but when I click on upload then it stops. .. What messages appear in the Java Console? Does the code of the applet [swallow exceptions|http://pscode.org/javafaq.html#stacktrace] (<- link)?
..So my question is:
1. Have I also need to sign all dependent jar files?What dependent Jars? The applet element shown lists only one Jar in the archive attribute.
2. My directory structure is as follow:
C:\AppletPage.html C:\Test.jar C:\libWhat (if anything) is in 'lib'?
