WSUS

Recently I had to install and configure WSUS (Windows Server Update Services) on our company.

I feel this is a very handy way to distribute the software updates through out the company.

In configuring it the following articles was helpful to me so thought to share them with you.

This is the main Microsoft site for WSUS,

Editing NTFS Drive Contents on Mac OS

In Mac OS if you mount a disk formatted in NTFS file system, you will be able to view the contents and even to copy contents from that disk (Read) but you will not be able to save, delete or paste (Edit) anything.
To enable editing in the disk you will be needing to install the NTFS driver.
If you are searching for a driver, download NTFS-3G Stable Read/Write Driver from NTFS-3G.

Then it will show options, letting you proceed or cancel the reset. Remember hard resetting will wipe all the applications and data in your device, so remember to backup everything before performing a hard reset.

Distributing BlackBerry Applications Over Internet

BlackBerry applications that you develop can be distributed over the internet quite easily when you know what you need to do. In this method users need to browse to the web URL and click on it so the BlackBerry will download and install the file automatically.

Step 1 - Prepare the Files
When you compile the source code of the application you will be getting a .cod file.
Check the file size of it, if the cod file is less than 55KBs then you can use it without doing anything more.
If that is larger than you need to do the following trick to make the application distributable over the internet.

• Change the extension of the cod file to zip.
• Unzip the zip file.

You will now see a set of cod files with names like App-1.cod, App-2.cod, App-3.cod, etc.

Step 2 - Prepare the Server
To make BlackBerry devices correctly identify and download the files you need to add or update the Multipurpose Internet Mail Extension (MIME) types in your web server. The required MIME types are as follows.
File Name Extension - MIME Type
cod - application/vnd.rim.cod
jad - text/vnd.sun.j2me.app-descriptor
jar - application/java-archive

If you need more details on how to set MIME types in different web servers please contact me, I will try to provide you with more details.

Now place the cod files we prepared in Step1 in the server.

BlackBerry Network Diagnostic Tool

Latest BlackBerry smart phones are supporting many different network transports to enable reliable data communication between third-party applications and the Internet.

BlackBerry have provided a good tool named "Network Diagnostic Tool" which is essentially a role model that answers all these questions and is a functional diagnostic tool for testing a URL over various transports supported by the BlackBerry solutions, as well as for displaying the values of many network attributes during the test period.
You will be able to download it freely from BlackBerry knowledge base.
If you need to know more about the available transports and more in depth details on the network diagnostic tool, better visit the Article Number: DB-00684 at the BlackBerry knowledge base.

Setting APN Automatically

If you tried to create a BlackBerry application which uses internet through Direct TCP transport and needed to release it to a set of users who are using different mobile networks you may have had the problem of how you can release the application in a way that users don't have to make any setting changes to make your application get connected. The complexity here happens because different service providers (mobile networks) are using different settings (for example APN).
After some searching on the net I found one way to achieve this is by identifying the mobile network and then setting the connection properties appropriately.
The steps involved is as follows.

Step 1
Identify the network the phone is currently in.
If you need help on this go to this URL.

Step 2
Get the APN settings for your network.
The way here is to have a file with all the settings of different wireless service providers you intend to run your application on, and then compare the value returned from Step 1 and get to the particular APN.
I suggest you to keep a XML or text file with the following details of the service provider,

• Country Name
• MCC
• Carrier Name
• MNC
• TCPAPN
• TCPAPNUserName
• TCPAPNPassword
• WAPAPN
• WAPIP
• WAPPort
• WAPUserName
• WAPPassword
• WAPSourceIP
• WAPSourcePort
• IsEnableWTLS

Step 3
Add the APN to the connection.
If you need help on this go to this URL.

Determining the Network

In the BlackBerry project that I am in now we are having the requirement to detect the mobile network the phone is currently in.
Basically in BlackBerry mobile network is uniquely identified by the Mobile Country Code (MCC) and the Mobile Network Code (MNC).
To get these details from your code what you have to do is to call

RadioInfo.getMCC()
and
RadioInfo.getMNC()

These will return the codes in decimal.
You can find a full list of MNC codes of the mobile phone operators and a list of country codes by following the following URLSs to Wikipedia.
http://en.wikipedia.org/wiki/Mobile_Network_Code
http://en.wikipedia.org/wiki/Mobile_Country_Code
