JDK 7 With Netbeans: FTP Problem With Windows Firewall

Yesterday I installed Netbeans to my Windows PC and tried to add a remote PHP project. I want to say that 1 day before, I installed same version of Netbeans to my Mac and added the remote project, there were no issues.

But yesterday, I was unable to add remote project, no matter what I tried, it was unable to add, giving the error that there is no file on the remote folder. The connection was tested and working too.

So I tried to disable Windows Firewall and ta-dah! It worked. What confused me is that first time I opened Netbeans, it warned me that there might be issues with Windows Firewall and prompted the classic Firewall pop-up to me to either allow or block the application, and I allowed. But it still was unable to get through.

Some searches guided me that that was a problem with JDK 7 and some people downgraded to JDK 6 were able to connect FTP folder.

But I didn’t want to downgrade because it was loooking too unnecessary to me. I mean, this is JDK and Netbeans, seriously, no solutions?

Anyway, I was too sleepy to fight with firewalls or libraries at that moment, I slept. This morning, with a fresh brain, I found out that “The only difference between JDK7 and older releases is that the JDK is using IPv6 sockets when IPv6 is enabled and so IPv4-mapped IPv6 addresses are used. it may be that Windows or the firewall is not configured to allow IPv6 sockets.”(1)

And there was a command that worked for some people(2). I tried, it worked for me, too.

What you have to do is open MS-DOS with administrator rights and paste this, hit enter. Probably, it will work for you, too. Hope so.

netsh advfirewall set global StatefulFTP disable

Add a Link Button to Navigate Previous Page

In my Asp.Net web page, I had a trouble with navigating to the previous URL. I guess possibly because of postback, my linkbutton was navigating to the current page when I use this method:


I was unable to give previous page’s URL as a link simply, because there were a lot of data so it always was taking a while when I “navigated to the last page” with this method.

Then I saw this great JavaScript method and it works perfectly so far. All you have to do is to insert a Asp:LinkButton then add this to your Page_Load event:

lnkBtnPreviousPage.Attributes.Add("onClick", "javascript:history.back(); return false;");

How to Find Installed Microsoft SQL Server 2008 Product Serial Key

Recently I had to find my original product key for MS SQL Management Studio 2008 in order to make a new installation, but I lost the key information I stored somewhere. So I tried to get the key from already installed product. First, I found the query for getting the key for Studio 2005, then following comments were including the key for 2008, but in 164-byte binary value… After more Googling, I found this great post at Branch Bits and it was sharing a program that converts this binary value to product key! Anyway so I used it and installed successfully.
Here’s the query that gets the serial number in binary format:

use master
exec xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\100\Tools\Setup','DigitalProductID'

And this is the source link.

And here is the link that you can get the project and use it for converting serial number:

P.S. For those who needs to find key of 2005 instance may use the free software named ProduKey. It works well for me.
