JavaMail applet problem

Hello
I try to send email by applet and I have a ploblem.
First of all, I pack JavaMail and JAF into my Cabinet file (.cab). Compile
java code, build and sign cab file are fine.
When applet run, It stuck at Transport.send() function without any exceptions
occure on java console.
This is print out from java console.

Thank you.

PS. I am apologize for my english.
My environment:
- Win98se
- IE 5.0
- Microsoft SDK for Java 4.0
- JavaMail(tm) API 1.2 release
- Javabeans(tm) Activation Framework 1.0.1

My 3 source files:
1. msgsendsample.java (applet version -- modify from javamail1.2\demo\msgsendsample.java)
2. smtpie.html (just applet tag)
3. smtpie.bat (for compile, build cab and sign applet)
