before going into technical, when things come to politics they can do what ever they want to do with iran regardless of the laws! we have to face this, most of them(americans) hate us, and consider us their number enemy, the rest work for the companies owned by jewish community which hate us.
even before thte open  source annuncement sun  has no legal reason to block iran from downloading  java, other than considering java  very high tech, since JAAS is under export control restriction, but you could download .Net, Oracle, Novel Mono, and different linux and BSD's, which each included some more high tech products falling into same export control laws. I think thats just political.

going back to technical issues,

not ALL of jdk is open sourced at this time now.
they are moving into open sourcing all portions of JDK and JVM but tht process is not finished.
they mosy get ride of commercial codes and some legal issues to finish the process.
take a look at this URL:
https://jdk.dev.java.net/
this colored tree shows which parts are open sourced and which parts not.
you may refer to this url to get better information:
www.sun.com/software/opensource/java/faq.jsp


you can download JDK from java.net but not from sun because JDK is dual licenced the one in sun can be considered the commercial one.

1) After sending previous e-mail, I read the GPL and I saw that
unfortunately GPL allows them to restrict access  to program  to
some countries, take a look at this snippet:

"8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces,
the original copyright holder who places the Program under this
License may add an explicit geographical distribution limitation
excluding those countries, so that distribution is permitted only
in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of
this License."

I am not an open  Source and free software  fan, but I think this
article is totally against the spirit of openness. What do you think?

2) If downloading  and using Java is not allowed in Iran, can we use
Java and Java EE to make commercial softwares? Is it allowed?

I know that sun  announced java  Open source  Program and
finally java got open  sourced. But downloading  java is still forbidden
for Iran residents. It is against the spirit of open source to limit
access to a Open Source Software And I think it is also against
GPL (Open source Java is licensed under GPL).

Any comments?

You can download JDK-6 from emule:

JDK-6 for 32bit Windows: ed2k://|file|jdk-6-windows-i586.exe|55740040|EC7F735B6BF93834D598BBAB070EA8BB|/
JDK-6 Docs: ed2k://|file|jdk-6-doc.zip|54897973|989199C26B8DE94BBAF853461055B79E|/

Simply put, these restrictions are all the result of Sun's stupid policies. Oracle, BEA, and a bunch of other Sun fellows do not seem to be any wiser as well.

Besides that, if you want something to happen, you have to make your voice heard by Sun executives, not us -- your Iranian fellow Java developers.
