Build .air behind HTTP proxy with login/password

Hello,

I'made an air application with aptana, bu I can't build my app in a air file.

I'm behind a proxy with authentication. I'got error during timestamp.

I try many options, I can't do this air file.

In another post a find :

"You need to have a network connection for timestamping to work. If that network connection uses a proxy server, you may also need to set up the JRE to use that proxy (Seehttp://www.java.com/en/download/help/5000020600.xml). "

But in the JRE option, I can't set a login or passorwd for proxy.

If I understand my compnany can't build air application ? or there is another soution ?

Thanks.
